  1. I think the mounting number of relic boats on moorings around the country is something we are just not prepared (yet) to face as a sailing culture that loves their boats. How many boats would be the result of deceased estates, where the relatives have no idea what to do with the boat?? Think how much mooring space would be freed up if these abandoned boats were removed? Surprisingly there appear to be abandoned boats on marinas now too, despite the ongoing cost. The reality is someone has to pay to cut these boats up and dispose of them. Many have no value. Even the lead value would be ea
  2. I'd be keen to come down and do that trip on Pulse. But can we have some sensible information regarding air draft. Or PM me please if you have info that you don't want public. It would seem my 16.3m air draft may be marginal??

    Oh my god, no ! Tim Clissold was 100% right. Oh my god, no ! Tim Clissold was 100% right. Oh my god, no ! Tim Clissold was 100% right. (I tried three times to quote this, but it was obviously 'quote protected', so I had to cut and paste! So it deserved to get pasted three times.) Well there is a sentence I never ever ever thought I would hear TimW ever say in public! Stop the world, miracles do happen!! Would you like some suggestions on the sheer web design of your next ones. Always happy to help! PS you've broken a boom too I remember. PPS I'm not the sort to say I t

    Everything but the hulls is wood core. Did I just shoot myself in the foot?... Actually all the sheer web are plywood on the 45˚ with DB over them. Mast, 3 beams, floors under the deck, etc. And Kauri in the foils as sheer webs, not cedar. But I have learnt a bit in the last 15 years since I built the foils first (in the project timeline)

    Western red cedar has density of 380 kg/m3. I can't find the sheer properties at hand but I would guess high density PVC foam is superior to cedar by far. The economical option is to link the two sides with double bias by splitting the centre core (if it has to be timber) and glassing the edges of the core to form two U sections, then glue them back together to form an I beam. Obviously you need to allow for the extra glass thickness. Larger centreboards (15m cats + ) are often solid glass at the hull exit as no core can stand the sheer or compression, especially when owners don't pull the

    I'd suggest that if you have to have wood in a foil then you need to use the strongest orientation of the grain to prevent a hull exit compression failure. It would be more efficient to use it like end grain balsa, ie with the grain running the shortest distance between the carbon flanges. The contribution of the cedar to longitudinal strength and stiffness compared to the carbon content is minimal. Using the cedar along the foil is relying on its core sheer strength. Remember how you split fire wood, along the grain. Imagine a plank lay up of a cedar core boat without the glass eithe
  7. scrubbed starboard (galley) hull front to back. Scrubbed decks. Patched bow from anchor dragging altercation. Boring. Made mounting for LED projector to go under deck tent. Much more interesting!
  8. Nice work, great to see it happening and good progress. But please, 18oz DB??????? We moved to metric 40 years ago.......... Were you trying to say 600 gm/m2 EDB?
