Topic: Building methods Posted: 07 Oct 19 at 12:54pm |
Having not totally kicked the idea of self build into touch, I wondered what the issues might be instead of using ply, but using that methodology, I substituted carbon and carbon foam sheet, could it be a 'thing'?
What would my issues be? Say for example I were to stretch a 3.7 plan out to 4.20 Using this sort of stuff for instance.? Edited by iGRF - 07 Oct 19 at 12:54pm |

Clive Everest built a sort of stitch and glue foam sandwich Cherub.

So just like a Foam Sandwich hull then... There was a guy in Paignton built a Fireball by making his own foam cored panels and a chap on FB built a Merlin using a similar method.

You can get brilliant white gel coat finished sheets of grp, perhaps similar to above post, stitch and glue.

Not sure about gelcoat, will crack as soon as the panel is bent. But Kevin Gosling has built a few Solos using foam cored ply.

100% read the OP about no ply but back in 87 speed sailing week in Weymouth I went to a talk by Dave Culp, USA kite sailing pioneer. He said he always built his boat and parts as a disposable. The ideology was that if you had too much (time/cost) invested in any part of the boat you wouldn’t take risks and if it didn’t work you would be tempted to keep it rather than move on. So for me ply is the cheapest and quickest - depending on shape obviously.

Just go for a epoxy ply/foam/ply sandwich. Super stiff and stays that way for decades. Dave Rose used to build his OKs that way and 30+ years later they’re just as fast as anything around now in the right hands. I guess you could build the panels on the bench and then put them together in a jig.

Clive built his Cherub using fibrefusion water jet cut carbon/foam/carbon panels.
It's a great way of building, you just have to be careful twisting the panels to form the correct curvature near the bow. |

Cardboard. Start with a cornflake box model of what you have in mind. Then make a dozen more until you get the shape you want.
