Building Paterson 8 in Dubai

[douglas_hassell]

Hi,
I have fitted some rack supports.  The height of the gunwhale is 390mm and I have raised that by a further 50mm.  I was wondering if this looked OK?

Pictures attached.  I have added one from the bow.  I am also keen to make sure that there is the ability to trapze directly from the hull...maybe I need to keep the rack support flat to help that?

I am ready to finish the supports and then put some uni around the top of the gunwhales.

Thanks,

Doug

I can't remember the exact height of racks at this point on E-numbers and would have to measure the boat.

It sounds similar though.  E-numbers is at the sailing club at present but I will be bringing her home on Sunday to check her over before the nationals. I can take some measurements then.

The issue that Will was talking about with respect to the beams catching spray was mostly related to the aft beams.  These on E-numbers do not catch spray and are some 50mm higher that on Antidote.

John made a point about reasonable space below the forward beam/wing for the spinnaker chute. We have 115mm between our deck and the under side of the beam at centre and 65mm and hull side.  This has proved to be a little low especially when we have the pole coming through the same gap and everthing wants to be near the mast stump. Another 20mm clearance would help a lot.

Thanks, having some measurements would be very helpful.  I presume the reason the rear racks as the boat is sailed upwind bow up? 

The transom measurements are 300mm to the top of the gunwhale and then I have an ear that raises the rack bottom support to 350mm.  The rack supports are angled upwards and so the outboard end higher than this.

In terms of  the front rack supports I plan to have 120mm at the mast stump and higher at the gunwhale.  So I think enough.

Thanks,

Doug

Doug,

it sounds about right.  The rear racks on the E5 are sloped up a bit so are higher outboard than at the gunnel.  The forward racks are sloped less because the gunnel like yours is higher than at the stern.

I can trapeeze off the gunnel and the racks quite comfortably in E-numbers. i will make some measurements on the weekend.

Phil,
Thanks.

I have been working on the rudder and have routed the dimensions onto the blank.  I am travelling again for a few days and will be working on the boat again on Thursday.

The dimensions you want from E-Numbers are:

height of underside of aft beams from hull on centreline:  350mm
height of underside of fwd beams from hull on centreline: 485mm

height of top of racks is about 580mm all round.

Thanks, I am back tomorrow evening and will keep working over the weekend.

The fwd beams are plenty high enough and do not catch spray. The tension strutts underneath occasionally catch spray when sailing in step chop. They are about 200mm below the beams where they meet the hull. The aft beams clear any spray by about 20-40mm.

Hi,
I know you are all getting ready for the Nationals and I hope you all have a good time.  I am continuing to work on the boat and do some travelling!

I am now turning my attention to spars and planning the mast, boom and bowsprit build.  I was wondering if there were some measurements and spreader heights, etc I could use to help me plan the layup?  Looking to use EJ cookbook.

Thanks,

Doug

Hi,
I hope you all had a good nationals.  I have a pic of the boat at the moment.  I have started filling and fairing the hull.  Rudder and foil also on the go.

I am preparing for the mast, boom and bowsprit!

Thanks,

Doug

Good stuff Doug!

It certainly looks like it is coming along.

From experience the triangular webs supporting the gunnels may get some abuse during the enevitable capsize or the ocasional slip and fall.  I would ensure that you have at least 2 layers of material over the foam core to avoid dents in them.

Alternatively you could bond and laminate carbon plates on to the triangles to mount fittings.

Thanks, I will add some more protection. 

(These are actually the bulkheads coming through the crew deck.)

I have built the compression struts and need to fit them.

Plenty to do but getting there.  My wife even said that it looked like a boat!

(I am looking for it to cool down...over 40 a lot of the time and September is also humid!)

Hi,
Back in the saddle!

Just had a month in Saudi conducting trials of equipment and systems and with organising that and moving villas in Dubai I have not done much in the last 8 weeks. 

Have been fairing the hull today and planning the rack tubes.

Rudder coming along nicely.

Also just bought a Beneteau 44.7 and will have my hands full in the new year.
