prototype belt lashing. The pipe is 22mm outside diameter with 3mm wall thickness stainless steel, bolts are 8mm. The sleeve through which the belt runs is fire hose which I believe is very resistant to abrassion. The hose was cut a bit too short in the protototype

how has this method of attachment  worked? not the hose part, but the moving all the forces to the deck part? How much reinforcement was done to transfer the loads? new transverse bulkhead? thanks. clif

this is close to the installation specced in the plans The only difference is the belt tensioning.

Boatsmith is right. The only part which is not to plans is the way I plan to tension the belt. The blocks on which the the crossbeams lay and the structure under deck is 100% to plans. The forces are led to the hull`s topsides and the bulkhead by a V-shaped plywood construction and a 4cm thick piece of hardwood under deck. The blocks are then bolted through deck and hardwood. A bit difficult to explain if you are not looking at the drawings.

Thanks Ralf,

you solution my problem with belt lashing's suplys, I will do like this.

Free-copyright? kkk...

 

One doubt , do you fix the beam block in deck before glass and mix, or after mix (epoxi+microspheres)?

I will fix my this week.

 

Thanks

Rogerio, It was not originallay my idea. An Australian builder named Lindsay came up with it some years ago and posted pictures on Scott Brown`s forum. He reported exellent results with the method.

I have glassed and faired the decks before putting the blocks on. I believe it is the only way to do it because you want good watertight protection under the slot (where the belt runs through) which is a spot very difficult to inspect later.

You are making quick progress with your boat! Looks good, congratulations.

Not too fast what I want , but we do the best we can do.

I have a lot of doubts, I have only you WBF's exemples. The only Warram most closely is 500km from my house.

Here in Brazil, everybody loves the monotypes and races. Cruising in a multihull is rare...

And is my 1º boat build...it's scares me

Thanks

Rogerio
