Fedor,
Too big/fragile, but I am getting used to it. See what happens when the sail is up.
Launched on Saturday, motored it up to the beach in 30 knots wind against tide with an old 6 hp outboard on an alloy dinghy. No big deal as long as it was pointed into the wind. Only draws a couple of inches/centimetres so there is nothing to stop it blowing around. Left it on the beach overnight, put the tramp on today. Pick up the sail tomorrow (I hope) and see whether the hoops etc work.
Launch video on the web page shortly.
