My neck having been broken when we fell in a Mother of a hole on the Round the Island off The Nab when in the lead in '89 ( Verterbrae was welded together with a bit of my hip ! )

Primarily built for 'Gastronomic Raids' on the French Coast and Poker runs the boat wil be fitted out fully over the winter as a cruiser / poker runner for 2011.

Hope it's not too rough for you old boys then! Good luck and really wish we could be there!

By the way what's the UIM length of your boat?

Approx 33'10 "

I wonder what the UIM measurement for a Sunseeker XS200 is as I would imagine as I mention on another thread it must be around that length to, was it Scott that ran the ex P1 last year so I guess he'd know

Nice touch with the termination of the spray rails - looks good and benefitual

Aligning/Mating the flanges of both 'halves' of the mould.

What he said! the flange was also drilled before separation so that the two halves can be bolted together while they are seamlessly joined - all will be revealed in due course!

Another race another dealine missed I'm afraid - you can't hurry perfection!

Some photos of the balsa going in the bottom of the hull - the next stage is two layers of woven combi mat over the balsa, more balsa on the sides and the same layup over that then it's time for the "Hog", longits and engine bearers - the deck complete with screen plants is waxed up ready for gel now so it's coming along nicely!

Cookee · 08-09-2010, 01:38 PM

Looking forward to hearing how I'm building the boat wrong from some transatlantic numpty!

jw. · 08-09-2010, 01:55 PM

So as not to disappoint you Cookee, will a numpty from north of the border do? What is the thinking re attaching the longits to just the two layers of combi mat rather than directly to the hull with the balsa either side of them? Ta.

Why would you want to interupt the inner & outer laminates that create the I beam? you'd end up with a hinge where the longit interupts the inner laminate. that inner laminate, when undisturbed can be put under enormous tension/compression

It's not like it will just sit directly on the two laminates, it'll likely sit on a beefed up foundation.

Well I read it as though it was the intention to be just the two laminates.

What he said!

The whole thing about a monocock (sp) construction is to try and remove any hard points and make all of the stresses and strains flow, so putting the hog and longits on top of the balsa distributes their strength really well, and as Jon says it lets the balsa do its job really well.

The bottom balsa will have the two layers of combi on it and then the basla will be layed up over the ends of where it meets the side, the side top layers of combi will then flow onto the top pf the bottom layers making it very strong indeed!

jw. · 08-09-2010, 03:48 PM

Okidoke, thanks for that.

a26 · 08-09-2010, 06:02 PM

hello everybody.

interesting thread.
just a question. I always have been told to avoid sandwich construction in the bottom, to prevent cracks coming from the slamming.
Even in the yard where I work, laminate is done only in fiberglass+kevlar for high speed patrol boats bottoms. then sides are sandwich and deck too.

if I am not wrong I have seen buzzi too, that makes this construction solution, so It must be strong enough...but I did not know
good to know

mould is looking great!

FLYING FISH · 08-09-2010, 06:41 PM

Not a true sandwich bottom,only the aft sections. (Miss Embassy)

One of the few sandwich bottoms made.

Jon Fuller · 08-09-2010, 07:12 PM

White Iveco had a 2" balsa bottom. Steve Baker looked with interest when it was holed in ramsgate on a bollard.

Swipes entire running surface is 1" balsa/Aramat sandwich.

Honey Party was 3" balsa bottom, and I understand some of the class one cats have 5" cored bottoms in places.

So not that unusual.
