The Sixties and Earlier

In the early days design numbers in the UK seem to have been kept in step. For instance so the only recorded Jeffries design is the Jeffries 5, a Greg 5 development. U.K. development was not really influenced by the Antipodes until the Spencer 7 was introduced.

This is a list of U.K. Cherub designs compiled by various people over the years. It is believed to comprise all designs built in any numbers, and the vast majority of one-offs. The line drawings should be helpful in gaining a feel for the shapes of the designs involved, but are definitely not warranted accurate.

Spencer (modified) mk2 (NZ)

Adopted as a one-design when the class was introduced to the UK. Many different deck layouts. These early boats are typically fairly narrow with small transoms and plenty of rocker, especially forward of the mast. A boat of this era looks something like a small Scorpion.

Spencer 2a

No built in buoyancy, bags under decking. e.g. 151, 258.

Spencer 2b

Conventional built in bow and side tanks and also a stern tank. e.g. 154, 645.

Spencer 2c

Double-bottom self draining. e.g. 155.

Spencer 2d

Fully rolled side tanks, with or without stern tanks or semi-length false floor. e.g. 157, 634, 650.

Spencer 2e

Conventional bow and side tanks with hinged plate instead of dagger board. e.g. 695.

Casson 2

Full main bulkhead, minimum width side tanks, daggerboard. e.g. 629.

Gregory 2

As Spencer 2d, but with full length hinged plate. e.g. 660.

Gregory 3

The first real UK design after the NZ restrictions adopted. Wider chines at transom, full length centrecase, low bow tank, double skin floor. Early versions 703, 704. Later versions had side tanks widened aft. e.g. 717,738,918.

McCutcheon 2

Similar to Mk 2e but with wider transom and half height bow tank. e.g. 709, 735.

Casson 4

Similar to Mk 3, but with shorter plate, single skin floor and full main bulkhead. e.g. 727, 1006.

Hawkesworth 2

Similar to Mk 2d, no stern tank, wider transom, bulge in bow sections. e.g. 698.

Gregory 3a

Similar to Mk 3, but with integral spray chine forward. e.g. 921, 923, 1002.

Gregory 4/4a

Somewhat wider than Mk 3. Again the a denotes the presence of the spray chine. E.g. 1010.

Gregory 5

More beam but narrower transom. Fuller bow with integral spray chine. Max. rise of floor at mid-length. e.g. 920 1005.

Gregory/Howard 5

Extra beamy version of Mk 5. e.g. 1012.

Jeffries 5

Basically a simplified dagger plate version. e.g. 1008.

Gregory 6a

Max chine beam further aft, spray chine, narrow side tanks, very wide. e.g. 1017.

Gregory 6

As above but no spray chine. e.g. 1018.

Gregory 6p

As above but hull in glass fibre and slight reverse camber in topsides at transom. e.g. 1019, 1020.

Forman 1

Extreme Mk 5 development, 6' ,3“ beam, no spray chine, plate retracts under foredeck, semi-rolled decks. e.g. 1025.

Spencer Mk 7 (NZ)

John Spencer's Mk 7 design was built in considerable numbers both in the UK and New Zealand. Orthodox dagger plate NZ design. Shallow foredeck rise, sidedecks slope down outboard and merge with foredeck. e.g. 1361, 1363, 1372

McCutcheon 8

Modified Mk 7, with fuller bow sections, hinged plate, inward sloping sidedecks. e.g. 1015, 1369.

Barton/Spencer 7

Mk 7 with forward retracting plate. e.g. 1377, 1510.

Forman 2

Narrower development of Mk 1, 5' 8” beam, cambered topsides, convex fwd, concave aft. Sliding plate. e.g. 1496.

Forman 3

6' 3“ beam, extremely narrow bow, chine angle disappears at transom, sections more rounded, less veed. e.g. 1652.

Spencer 8 (NZ)

Design for heavier crew weight. Wider chines than Mk 7.

Spencer 7b

GRP version produced by Peter Caisley.

Caisley/Steele 1

Mk 7 with swinging plate.

Jennifer Julian (Bowler) (NZ)

Narrow beam, deep veed, low keel rocker. Versions exist in ply, GRP and GRP/foam sandwich. e.g. 1717. Russell Bowler won the first (1970) World Championships, held on the Swan River, Perth, Australia. Russ' Bowler is now a partner in Farr Yacht Design

Thanks to Russell Bowler of Farr Associates for making original drawings available to assist in preparing this sketch. Plans would be available from Farr Yacht Design by arrangement. Foam Sandwich construction seems to have started in NZ with 12ft Skiffs. According to Richard Gladwell of Sailing NZ:-
“The foam skiff saga began in 1968 with the construction of Query by Don Lidgard and Tony Bouzaid - it was a 12ft skiff and went on to win the Interdominion in 68/69. Query was the second 12ft to be built in foam - the first was Miss Hycel, which was shaped from a solid block of foam in 1967. But Query was the first planked boat. Then followed two 18ft skiffs - Miss IGA for Dave Kean, later - Theory for Lidgard and Bouzaid. Jennifer Julian, the 12ft skiff, was the first round bilge foam skiff, and was built by Russell Bowler and Dave McGlashan, who were the current National Cherub Champions. In the 1968 season there were five foam boats launched.” Jennifer Julian, the Cherub, was actually built in Perth. Russell and Peter Walker were living om actually didn't qualify for the NZ team for the first Worlds, so they moved to Perth and built the foam & glass Cherub there, and subsequently won the Worlds in it, presumably sailing for Australia! Russ then went on to England, and helped to build at least one foam sandwich boat in the U.K. with David Steele. It seems likely that this was the first foam sandwich racing dinghy built in the U.K.

Banshee

anonymous@undisclosed.example.com (Anonymous) — Wed, 09 Dec 2020 19:21:55 +0000

Banshee

In a nut shell the aim of the Banshee design was to develop an competitive hull shape with easy handling. Speed weighted toward the lower summer championship wind range but with the easy of handling making up to any loss of top end when the dogs were off their chains.

New Zealand designer David Lee was commissioned by Daryl Wilkinson to develop lines based around this concept from his highly successful 12-foot skiff , Nuplex, multiple 12-ft skiff Inter-dominion winning boat. With regular conversations and observational input from Daryl the 'Banshee' was penned.

Daryl designed the rest of Banshee Ambulance to be a multi mode boat, allowing for several different ways of sailing.

All hulls have been built by Mike Cooke at Aardvark Technologies Aardvark.

Due to Daryl being the slowest of slow when it comes to finishing his boat the sail registration got out of sequence with the hull build dates.

This is what David Lee has to say about the new design...

This design is an evolution of my Nuplex 12 foot skiff design I did with Alex Vallings. Nuplex, for those who don't know, was a very skinny 12 to start with at around 700mm maximum between the chines and a nice fine bow. Alex found the design to be safe and fast in a straight line, but didn't carry speed through the tacks and it didn't perform as well as the woof design when he wanted/needed to sail deep downwind in marginal planning conditions. This was due to the lack of volume in the aft of the hull. The solution was to widen the design in the aft. So I redesigned the aft of Nuplex in 2004 making the maximum width between the chines around 850mm and Alex rebuilt Nuplex in 2007. I realised and so did Daryl that the modified Nuplex design was very close to meeting the UK Cherub rules. The changes necessary to make the design meet the rules were to make it a little wider and raise the forward chine slightly so the integrated topside/snout was possible. I also made a few changes to the shape to reduce drag at slow speeds as a Cherub is not as powered up as a 12 and hence will spend more time at displacement and transition speeds during a race.

Comparisons of drag prediction estimates of the Banshee design to other 12 foot skiff designs is shown in the graph below with the well proven Woof design used as the benchmark. Please note that these estimates are averages over a number of different drag estimation methods taking into account different speed ranges and other limitations. None of these methods take into account the crews’ ability to optimize the hull trim for the speed and only partially take into account the effect of dynamic lift and the associated reduction in wetted surface area. So taking the limitations into account what does the graph show; The Banshee and the modified Nuplex both have more wetted surface area than either the original Nuplex or Woof, which is shown by higher drag below 5 knots.

The Woof design has more of a hump in drag around hull speed in comparison to the other designs. From real life experience the drag of the original Nuplex at early planing speeds is under estimated in comparison to Woof due to the under estimation of the effects of dynamic lift on drag. Considering the changes required to meet the UK Cherub rules the Banshee performance should be similar to that of the modified Nuplex design.

So, how does the Banshee design compare to other UK Cherub designs as seen from a far? It should have a finer bow and most likely more rocker on the mid-forward keel line. It should be faster upwind in almost all conditions and faster downwind in light conditions and hold its own in planning conditions. The design should be safe (relatively) due to the fine bow and progressive increase in volume in the bow, meaning you don't slow down as quickly when you run into the back of wave giving you more time to react. The design is a compromise aimed at winning races, not winning the blast to/from the race track.

Big Issue

Pill Morrison National 12 hull shape modified to UK Cherub rules.

Original design ethos

Taken from the National 12 website:

Designed by Phil Morrison in 1997/98 with high speed off wind performance in mind. The hull design was influenced by Phil's design work on International 14s. Big Issue has a double bottom with a raised shear line.

The boat has at times shown bursts of phenomenal speed both upwind and downwind and has proven to be a good all rounder with good tacking ability in light winds

Italian Bistro

anonymous@undisclosed.example.com (Anonymous) — Wed, 09 Dec 2020 19:21:55 +0000

Italian Bistro

Dave Roe design with input from Kevin Ellway. Name sourced from “BistroMathics” in “Hitchhikers Guide to the Galaxy” by Douglas Adams. The first Bistro was Dave’s own Norwegian Blue, and was an immediate success. A female mould was flopped of Norwegian Blue by Wiz Deas. He built 2641 and 2642 out of this mould. Biffa Baker built 2647 out of the mould for Graham Dickenson. Many other Bistros were built off Dave’s original building jig. The mould was also used for several amateur boats and destroyed in the building of the last of these by inadequate release agent.

Very influential flat low rocker design. quite fine V bows, moderate beam, low rocker and rise of floor. A breakthrough design and faster than anything before in almost all conditions. The first Bistro, Norwegian Blue, won several successive National Championships, numerous major UK handicap events, and was the top UK boat in the 1996 World Championships.

Cardinal Sin

anonymous@undisclosed.example.com (Anonymous) — Mon, 31 Jul 2023 18:42:06 +0000

Cardinal Sin

This design came about when Richard Taylor was thinking about a new boat in June 2006.

He sold his Pasta Frenzy The Spanish Inquisition and set to work. What he wanted was something very Slug-like, but with a little more buoyancy at the back end to help reduce low-speed tail-sinking, especially with the larger helm.

The Cardinal Sins are built by Aardvark Technologies, the builders of successful Cherub Loco Perro.

Here are all the pictures of Cardinal Sin in production we have, automatically pulled from the archive.

Cardinal Sin News

Cardinal Sin

Richard Taylor, former owner of Italian Bistro 2655 “It's Me Too!” (now Monkey Magic) and Pasta Frenzy The Spanish Inquisition has collaborated widely with the class to create his first design, called Cardinal Sin. This Slug-inspired vessel has been in build at Aardvark Technologies, and everything is being built from female moulds to facilitate production of Cardinal Sins.

The plug nearing completion.

“To the Bat-Skiff, Robin!” (said Batman)

Aardvark Technologies are taking orders for Cardinal Sins now, but they are incredibly busy so if you want one, don't be shy!

Cardinal Sin Update

Cardinal Sin is nearing the completion of the tool set at a rapid pace. Team Aardvark have done a fantastic job in moving this project along so quickly. The Hull tool will have come off the pattern by the time this update hits the web and Charles England at Sea Solutions is well on the way with the foils from the class mould. The most superb C-Tech rig arrived by air freight last Friday complete with bowsprit and oval boom.

Mike Cooke at Aardvark estimates 4 weeks before the first Cherub from a complete production tool set comes out of the workshop.

This weekend sees some long hours with SolidWorks CAD package to finalise the Bill of Materials and final design layouts. It will also see the first serious production parts drawing for “T” foil components that use lightly modified windsurfer skegs with some CNC manufactured parts. There is also a really cute solution for quickfit rudder attachment too.

If you're interested in a new boat don't hang around. I'll be machining parts in the next week so please get in touch as there are economies of scale to share in making multiple CNC parts. richard_taylor me to find out more.

The Cardinal Sin Project gallops towards completion by the day. This is a moderate development of the successful Slug design, with some extra attention paid the static fore-and-aft stability and to in-boat ergonomics too. Today's news is that the specifications for the fittings of the whole boat is now done, and the hull mould is going off, due to come off the plug tomorrow. In the mean time here is a CAD image to keep you happy.

Two Cherubbists Tie The Knot

On Saturday 14th October 2006, the keepers of Primal Scream Phil Alderson and Carol Low were married.

Congratulations from all Cherub sailors - past and present - and best wishes for your future together.

Special Note 1: The most hydrodynamic flower pot in the world - Beside the happy couple is a beautiful model of Primal which was a surprise addition to the proceedings provided by Carol's brother David.

Special Note 2: Malcolm Garrington the best man sailed with Phil in his previous boat AquaMarina in 2004.

Special Note 3: The venue of Largs sailing club was fabulous - you can see Great Cumbrae Island in the background.

Special Note 4: The hymns were sung accompanied by North Tyneside Steel Band who also provided exceptionally appropriate music at every stage of the evening. Highly recommended, especially 'Dancing Queen'!

A really splendid event to mark a very special occasion. Also amazing fireworks over the water - fabulous!

Daemon

anonymous@undisclosed.example.com (Anonymous) — Wed, 01 Mar 2023 18:40:16 +0000

Daemon

So here it is! The Cherub Dæmon, a stripped down and pumped up production skiff designed specifically to target ALL the ISAF requirements for the proposed Women’s Olympic Skiff.

rich_taylor us to show your support for the project.

You are probably asking yourself why?

Well the short answer to this is necessity. Quite simply, there are production skiffs on the market and they do fit the ISAF requirement to a degree. However, some of these classes are restrictive and boats depreciate rapidly as there is no alternitive class to sail them competitively in.

For this reason a few like-minded members decided to galvanise and execute a project that would bring a viable alternative for the ISAF committees to consider.

The Daemon is our proposal, it is a strict Olympic One-Design and conforms to the Cherub class rules, this will automatically give all Daemon equipment a second lease of life inside the Cherub Development class rules and an alternitive fleet for owners to sail or “cut their teeth” in . Our proposal and design has a solid commercial plan and financial backing in the form of Hartley Laminates who have worked closely with the class and ISAF to ensure all product & commercial targets are met.

Now you are asking yourself how?

Creating the theoretical plan is relatively easy; executing and delivering it to market as a production boat is the hard part. Turning the Daemon into reality has been achieved by a hardcore of dedicated Cherub sailors with the collaboration of an exceptional production builder, Hartley Laminates.

In early 2006 the Dæmon project was conceived, by August the plans & tooling forms had been constructed on CAD with the help of Simon Roberts. Early September saw the creation of tooling patterns and in October the first complete hull emerged form the Aardvark workshop.

Gradually, as the ISAF specification became more detailed, we realised that the Cherub design & ethos fitted the criteria exceptionally well and we learned that a serious submission would be welcomed by ISAF.

In February we made our submission with supporting documentation at the ISAF office in Southampton. It was a truly important day as the previous year’s activities had successfully be kept secret but in a few short days time the applications would be made public and our commitment known.

Testing the water

The first Dæmon “The Subtle Knife” was already public, it had been pictured on Cherub web site and also the ISAF release. What the competition did not know was that there was a second boat and a production builder that were waiting to launch.

Hartley Laminates unveiled their Cherub Dæmon to an unsuspecting audience at the RYA Dinghy Show at Alexandra Palace. The boat created a real buzz and many serious enquiries.

It was now clear to all, the Cherub entrant for the Women’s Olympic Skiff was a very serious proposal with the backing of a large production manufacturer as well as widespread support of the public. <html><center>

Where to now?

The Hyeres trials in April are the next step in the ISAF process. Two Cherub Dæmons will be there together with crews and support team. We are there to present a serious alternative to the currently prevalent single-manufacturer system as we believe that it is important to support regional sailing industries around the world to broaden the appeal of sailing and to bring women's Olympic sailing into the 21st century.

ISAF Women's Olympic Skiff Trials Day 1:

16th April 2007

Today was the first day of the ISAF Women's Olympic Skiff Trials in Hyeres, France. The two Cherub-Daemons were joined by four other teams, The RS800, the International 14, the 29er and 29erXX and the GT60.

The 0930 briefing gave us the opportunity to meet the evaluators and the for the teams to introduce themselves. The Cherub Daemon Team is being represented by Richard Taylor, Tim Coventry, Derek Clarke, Tim Noyce, Matt Albiston, William Lee, Lucy Lee, Tom Kiddle, Stuart Hopson and Ant Chapman.

The briefing was followed by an inspection of the rigged boats by the ISAF committee, ISAF designated evaluation sailors and the other teams. This allowed the teams to compare the boats and the evaluators to see what they would be sailing.

The Cherub Daemon was able to demonstrate its unique T-foil system with a mechanism within the tiller controlled by twisting the tiller extensions.

Following the formal inspection of the boats, there was a period of hours while the breeze filled in, where there was much informal discussion and demonstration.

The format of the event over the next few days will be that five pairs of ISAF evaluation sailors will sail each boat and report their impressions. These are drawn from the very best female sailors.

Today, the sailors in the Cherub Daemon were International 470 sailors Rachel and Rebecca from the UK.

The Cherub Daemons were the first boats to launch with one evaluation sailor in each boat, paired with Tom Kiddle and Stu Hopson. The wind was initially light and patchy, so the crews were able to become familiar with the layout before the breeze filled in a little. After a short while Rebecca and Rachel swapped to sail together, getting to grips with the new techniques required in a twin-trapeze asymmetric with T-foil.

Most of the afternoon was spent sailing around a small course in company with the other trial boats.

There was no formal racing, but there was some friendly rivalry between the Cherub Daemons which kept it lively. As you can see from the GPS-track, courtesy of our Nationals Title Sponsors Velocitek, the Cherub Daemons did not hang around offwind, even in the light conditions, hitting 12 knots at times. Both Cherub Daemon crews were very pleased with the performance compared to the other boats in light airs with the T-foil rudder providing a clear performance enhancment in these conditions.

“Today was a chance to show really excellent female sailors this terrific boat.” says Lucy Lee, Cherub Class President, “I am thrilled that they found it such an enjoyable and challenging experience, and were able to see for themselves just how well it fulfills the ISAF's criteria for the proposed Women's Olympic Skiff. ”

Richard Taylor, Daemon Project Manager, added “Hartley Laminates have really pulled this off. The boats look excellent and have drawn admiring glances from everyone, including teams preparing for the regatta here next week.”

The evaluation continues tomorrow.

ISAF Women's Olympic Skiff Trials Day 2

17th April 2007

The second day of the ISAF Women's Olympic Skiff Trials was characterised by moderate breeze in the morning in beautiful sunshine, and less breeze resulting in tow-ins for many in the afternoon.

The allotted trial crew for the Cherub Daemon were Maki and Mitsui, the nominated team from Japan. These two rigged one of the Daemons themselves under the guidance of the Cherub Daemon team. They then assisted with the short and easy lift to the water right around the other boats waiting patiently to use the slipway.

Maki sailed as crew in one Daemon and Mitsui sailed as helm in the other with Cherub Daemon team members filling in. Once out of the harbour the next half an hour was spent showing them the ropes and demonstrating the T-foil system, both upwind and down. Before long these two 470 sailors took a Daemon between them and reported thoroughly enjoying twinning upwind and down in the building breeze, and experimenting with the unique twist-grip T-foil control, allowing them to push this ultra-light skiff hard in the lumpy water. Soon our new friends were whisked away to their next assignment by an official ISAF RIB and then the process started again with another pair of nominated sailors. Who could ask for more than bright sun, blue sea, fabulous breeze and a Cherub or two to burn about in? (with a RIB to carry the drinks)

After lunch (taken serially in the Hartley Laminates sponsored RIB), one of the US nominated sailors named Elizabeth enjoyed a marathon tacking and gybing session with a Cherub Daemon team member and the other boat was snatched for joyrides by the liveried members of some of the other teams - Naughty!

All too soon the breeze switched off and little tow from the RIB got the sailors home ahead of the rush to pack up in good time to go back to the hotel and look at the pictures, video clips, and, of course, our Velocitek sponsored GPS tracks.

More breeze is forecast for tomorrow, the third day of these four day trials.

PS Max speed recorded today was 14.7 knots (See the GPS track at: http://www.sailingsource.com/cherub/appletGPSAR/gpsar.html)

ISAF Women's Olympic Skiff Trials Day 3

18th April 2007

Today began with more light southeasterly winds and sunshine. There was a full house of ISAF nominated sailors in the Cherub Daemons to begin with: Hela and Marie from Denmark in one and Elizabeth and Caroline from the USA in the other. These two evenly matched pairs match raced as they put the boats through their paces. The Hartley Laminates RIB followed at a safe distance, taking photos and videos, answering occasional questions about T-foil use, but mostly looking at the incredibly high quality sailors and picking up tips on how to improve our own sailing.

The course was set as a windward-leeward with a leeward gate just to keep everyone together in the same place as the ISAF raters visited each boat to watch. The building breeze allowed for the boats to be used in every 'gear' by the teams. Hela asked for a Cherub-Daemon team member to swap in to demonstrate T-foil use, so she and Lucy Lee did a couple of laps, visited for a time by Team GBR Tornado Coach (and friend of the Cherub Daemon project) Derek Clarke in his RIB. He came to see how his rig alterations were getting on before going to continue with his team preparing for the Hyeres Regatta next week.

The Austrian team Sylvie and Sonia asked for a second shot in the Cherub Daemon and swapped to replace the Americans. They really enjoyed the extra speed available offwind when using the T-foil - especially as they had made full use of an of-the-water masterclass the previous evening in the boatpark, turning the extension and watching the foil change angle in a fully controlled environment.

After a lunch spent basking in fabulous sunshine and chatting with members of other teams, it was back on the water with the Swedish ISAF nominees, this time divided between the two boats with Cherub Daemon team members Ant Chapman and Lucy Lee filling in. These two Swedes soon asked to be together and spent the rest of the afternoon showing off the Cherub Daemons absurd pace upwind and down, with many spectacular gybes, hoists and drops thrown in.

The Japanese team of Mitsui and Maki also asked for another turn in a Cherub Daemon so it was a full house of nominees again.

All of a sudden at half past four, nearly at the end of the afternoon, an unsettling bank of sea fog rolled in from the southeast on the breeze. As the landmarks, yachts, RIBs, and other close-by boats disappeared around, the Japanese team were just swapping into the RIB for a Cherub Deamon team pair. This was enough time for the Swedish team to be out of sight - and this was the boat without a full featured GPS aboard. The wind stayed up while the fog was in, and everyone headed for shore. The RIB arrived at the harbour with the Swedish pair, who still had their kite up and flashly sailed right to the slip before a smart drop and jumping out. The GPS equipped Cherub Daemon appeared shortly afterwards, having followed the GPS track back in.

After the boats were packed up the Cherub-Daemon team made their presentation to the ISAF evaluation committee. This outlined the details of the boat and the wider proposal. This was well received.

Tomorrow is the last day of the trials, and with the presentations out of the way, the team can relax a bit and concentrate on helping the crowd of elite female sailors who want to try out the talk of Hyeres: The Cherub-Daemon.

ISAF Women's Olympic Skiff Trials Day 4:

Thursday 19th April 2007

There was much talk of more wind for this, the last day of these interesting and enjoyable equipment trials. All of the 'main business' of each of the nominated sailors having a sail in all of the boats and later filling in a questionnaire had been completed, so people chose which boat to sail.

Finding some rational method to choose a pair of teams to sail the Cherub Daemons from the moderately orderly queue of keen elite female sailors was a challenge, and in the end it was decided to offer sails to those who asked the earliest: This meant it was Lina Stroemquist and Tina Nilsson, two 470 sailors from Norway who had asked to have a go before the event even started in Badgers, and the Danish nominees Helle Orum-Nielsen and Maria Gade in Subtle Knife.

The wind was slightly fresher: It may have even had exceeded ten knots at times, and it was cloudy which gave the day a very different feel. After some sailing around a gate-start was arranged and the boats headed upwind on a short beat to a buoy. The RS800s and to a lesser extent the i14s got clean away, the extra rag, weight and length keeping them moving through the chop. Once the Cherub Dameon 'Subtle Knife' was clear to tack, that's just what the Danes did, and then they were able to put the nose down, get back and use the T-foil properly. Watching from the RIB the speed difference was immediately apparent and at the windward mark the Cherub Daemon was comfortably ahead of both RS800s, which were followed by both i14's. There followed a neat hoist and then they were away: Locked in on their way downhill: Unstoppable! They were persued by the evaluators RIBs: All eyes were on the Cherub Daemon! (See the pics taken by pro photographer Andrew Filipinski on www.digigraphics.co.uk - page 6 of the album has the sequence. Videos and GPS track coming soon.)

After this the breeze went down and there were some boat-on-boat rabbit-start exercises. Then, all too soon, it was all over. People were getting on planes, boats were having their masts taken down and being lifted onto trailers. It was sad to see that our experiences in Hyeres were coming to an end so suddenly: The chance to show elite female sailors, and the administrators of our great sport, what we have to offer - and for them to all absolutely love it - was really special.

The Cherub Daemon team at Hyeres was Richard Taylor, Tim Coventry, Derek Clarke, Matt Albiston, Tim Noyce, Ant Chapman, Will Lee, Lucy Lee, Tom Kiddle, Stuart Hopson.

The Ellway 6 EVO was spawned from the Arup Skiff project. This was an attempt to achieve selection for a Cherub derivative as the ISAF Women’s Skiff, selection was won by the 49er FX.

The Ellway 6 EVO is identical below the waterline to an Ellway E6, with key differences being the monocot wing support, a 100mm radius at the shear line, increased flair at the bow, a deeper crew deck and slightly raised wing bars at the stern.

Kevin Ellway's paper on the design considerations behind the E5 and the following E6 are detailed here

Note: Rough moulds for the first Ellway 6 EVO were fabricated in a hurry to prove the Arup Skiff concept could be moulded and more importantly released! The initial Ellway 6 EVO plug utilised a bottom panel derived from the Aardvark E6 tooling. Any further boats will be made from a fresh tooling set.

Kevin Ellway's latest design, the E6 Cherub, has started it's progress from CAD to the water. There is along way to go, but in the safe hands of Master Craftsman Paul Croote and Aarvaark we should be seeing a floating object before too long!

New Ellway 5 Design

Kevin Ellway has sent in a preview of a design he has been working on for Patrick Cunningham, which he though my be of interest.

Here is what he has to say about it:

The Ellway 5 design combines what I've learned from the SK4 design process, 4 years of sailing Beans (a Slug) with an 05 rig, and 32 years (yes really) of sailing cherubs into the design of an all round boat.

I have moved to slightly more rounded fore and mid sections than the SK4 due to the lower upwind speeds of the Cherub. The drag predictions are around 9-10% less than a P7 at speeds up to 8 kts. At planing speeds 10kts up, the drag is similar to a Slug, although drag predictions for non prismatic forms are a bit dubious using Stavitsky.

I will do an overlay with the slug, but basically the E5 is a lot finer in the bow and shoulder sections which reduces considerably the wave drag at high displacement/ semi planing speeds.

The design is still a lot more cherub like than the Bieker. This has a huge amount of chine rise throughout its entire length.

If anyone would like this design, it is free as long as the designer is acknowledged, but I would suggest paying the CCOAUK a donation of say £10.

I hope it is of interest.

Best regards

Kevin

Fartpants

anonymous@undisclosed.example.com (Anonymous) — Wed, 09 Dec 2020 19:21:55 +0000

Fartpants

The First “Narrow Flat” design. Slightly hollow V bow, low rise of floor, narrow beam, very flat floor with lots of turnup to chines and slight negative rocker aft. The Fartpants was something of a step forward as the first UK design that really kept up with the ex Worlds winner Flat Stanley in the majority of conditions. Designed to be a weight carrier.

Paterson 6a

Andy Paterson converted his Paterson 6 with snout and wide flares and won the 1997 Nationals with it. As well as the obvious wings and snout, he extended the bow rather than the stern and so made the bow slightly finer, and removed the charicteristic moth style high fordeck.

No boats were built to this design, but 2650/King Tubby was converted from Paterson 6 to 6a.

Slug

anonymous@undisclosed.example.com (Anonymous) — Wed, 09 Dec 2020 19:21:55 +0000

Slug

This design was the first to appear after the 1997 rule change. Simon Roberts drew a moderate hullform to be relatively easy to sail. It features a distinctively “wavy” flare line, and waterplane rather further aft than its rule-constrained predecessors.

Robin Russel built the plug, and set about building three boats. These were his own ‘The Green Slug’, ‘Born Slippy’ for Neil Cardno and Ken Scott-Brown (aka Team Scotland), and ‘Nautillius Pompillius’. These were vac-bagged in carbon.

Since then Ben Brown began to build a flairless Slug. This project was passed on to Tris Kemp and Rich Bower, and the completed shell came off the mould in Summer 2005 to be christened 'Hardly Sluggish. The seond flairless slug 'Atum Bom' was built by Andy Paterson and completed by Will and Lucy Lee in early 2006.

Squid

anonymous@undisclosed.example.com (Anonymous) — Wed, 09 Dec 2020 19:21:55 +0000

Squid

The Squid was designed by Mike Rolf soon after the 1997 rules changes. It has a very fine entry with flattish u-sections forward, minimal rocker and rise, and upright-ish topsides. The idea was that keeping the bow straight and fine should prevent most of the nose-diving that pre-97 Cherubs can be prone to. The design has shown plenty of speed at times, but is by its nature (flat with sharp chines) quite tricky to sail and you have to keep her very flat to avoid getting wet.
