[sailing] double-hulled small cruiser concept

For such a 'tubby' looking craft, there were years of thinking and abandoned designs before this one was finalized. If sailing's not your thing - kindly pass to the next post.

Trimarans, wing sails with twist, H105 foils, Eppler codes - I abandoned them all for low-tech but not as low tech as Wharram.

I settled on 23 feet as the optimal length for one-up and continued the low-aspect, low-tech throughout. Ease of sailing for a middle-aged duffer was the idea - hence two self-tacking mains, rather than the western fractional rig.

Equally, proas and crew-number intensive balancing acts were right out. Reefability, repairability, ease of sailing, speed, open deck lightness vs overnight accommodation - these were the considerations.

If this is remotely interesting for you, have a look at the sketch and notes.
