Nice idea about using the pultruded tube. I suppose with the narrower boats and T foils sticking the beak in isn't as bad as it once was. When I owned LFC Ben Brown managed to break the gunwale forward of the shrouds after going for a swing, after I'd stuffed it into a wave. He ended up with quite a monumentaly sized bruise!

The mast tubes are now formed.
Unfortunately once they are joined they will no longer fit in the shed.
Final cure and further work on them is going to be weather dependent.

 Looking fab. every time i look at it my thought go to whats it going to be like. Can I book a place for a ride or is Alex not allowing anyone else on it? Any thoughts on it being a 2 piece mast or is it just not worth considering?

I really enjoy seeing new innovation in the class. I've been looking at the hull photos again - it could just be the foreshortening effect of the camera, but it looks like you've got a lot more rocker there Clive than has been the fashion for the last few years. It also looks super-narrow. With the chines above the waterline the actual waterline beam could be very narrow indeed - is that right? It might need a highly talented Moth-style sailor to manage it. Wait a minute....

Hi Ade,
you are welcome to a go, It would probably be better to try it with Joe not me.
I had not considered a 2 piece mast. It is certainly feasible but as we leave the diamonds on I doubt that there would be much benefit, except when trying to fit it in the shed for finishing in the middle of a global warming aberration.

.....

Hi Neil,
It is a very long time since I sailed a Moth, I am sure that Alex's uni cycling skills will be more useful than my distant past.
I am hoping that the design is going to be easier to sail than some of the other new boats. I think that the solid wings will give more options on where to put our weight, and because we do not have as much worry about them hitting the water they are slightly lower.
This should make it easier to get up the high side, the COG is lower, it will heel further before it topples. When a wing hits the water at low speed it will not sink as fast, getting in after a capsize should be slightly easier.
The boat does have very slightly more rocker, 67mm total. I believe that this is the same as Ronin, and sailing against them we never saw that they had any issues with early planing or top end performance.
It is my intention to make a design that is light weather orientated. 1 minute in a light weather race is usually worth a more places than 1 minute in a race when its blowing 20kts.
The design with the lowest PY will not necessarily be the regatta winner.

I have always had a weakness in light winds and Alex's is already showing a reluctance to get out of bed if he cannot hear the wind rattling the windows.

It felt wrong last year sailing Subtle Knife that a RS200 would beat us upwind in the light but in 5kts more wind and we would lap it.

The bow entry angle is the same as an E5, and probably an E6/7 however the max chine beam is slight further forward.
Whilst the chines are slightly higher, and the sections rounder. I hope that it is not going to be any less stable than the other current designs.
It would be possible to build a much trickier but faster boat within our rules.
I also hope that the rounder sections will be more tolerant of inaccurate trim. We certainly saw this in I14s, and it made boats that you knew were slower very difficult to beat.
A boat with more rocker will be more stable in pitch and that this will allow us to run with slightly more T foil lift and offset the drag that the extra rocker has at higher speeds whilst hopefully reaping the benefits at lower speeds.
Whilst the rocker is higher by Cherub standards it is still very low compared with any other boat that I have been involved with.

Thanks for the reply Clive. You obviously have a very well thought out design philosophy. The rounder bottom sections and a bit more rocker idea is something that seems to have paid off in 12 Ft Skiffs as well. The Interdominions have just been won again by a Woof design hull which has a fairly round bottom and more rocker than a typical UK Cherub. Others have designed flatter, chined boats but the Woof has maintained it's dominance for many years now.
I like the solid wings design. I think your ship looks fab all round, and I'm looking forward to seeing it in action.

out of interest, do we know when and who he made his last cherub sails for? What were they like? My Batt is very old, very knackered but still ACE speedy!

Hi ade, Dick made me a set just before Christmas. I have yet to try then as I have had to increase luff length to get some extra area in resulting in a gooseneck move. I'll let you know how they perform after I manage to take them out for the first time.

If anyone is interested I have a suit of 05 Cherub sails made by Batts for sale. Brand new never used. If you're interested I can measure up!

'ello peeps.

The Batts Stu speak of belong to me, and they are for sale. They are unused and are currently in Mr Tinner's garage in London (correct me if I'm wrong).

If you order from Dick you will get a quality suit of sails and you may just get them in time for the 2020 Nationals.

The boat looks mint clive!

Looking at Clive's last photo am I the only one wondering where the buoyancy is?

Can't wait to see this boat in action! Looks absolutely awesome and very Gotham City

Clive, whats the colour scheme on this 'stealth batmobile type vehicle'? or is it still under the official secrets act and only on a need to know basis. I dont think it needs go-faster stripes though!

It is going to be white with grey progrip.
Not very exciting, but it makes it look like less of a one off, and the Durepox white paint is rock hard.

I hid the buoyancy under the floor.
