Thanks for your kind comments guys.
NED, she draws about 19 inches, its hard to be exact cos there isn't a waterline, but definitely no more then 20 inches, which is slightly less than my marblehead. Over the bank holiday weekend the marblehead was grounding out in a few places, since then the water level has gone up a couple of inches in our lake, but the marblehead still touches bottom here & there, but with this yacht, i haven't noticed that problem.
I am a little concerned that the sail size will prove too much for the HI Tec winch she is fitted with, but it coped OK last night in fairly strong winds, I guess time will tell.
Cheers Glenn
