Actually, left to its own devices my Greenland boat aligns itself
perpindicular to the wind and happily stays that way unless I do something
to correct it. I expect it's caused by pretty equal distrubution of lateral
area front and rear (you would expect the "tail fin" on a Disko Bay boat to
cause weathercocking, but that hasn't been my experience, probably because
it has a prominent bow as well). It also broaches quickly in following
waves. I think both problems might be corrected, or at least changed, by
putting on a skeg. I plan to try one of the strap-on types described in
Skinboats of Greenland.
The only complaint I have about my baidarka's performance (it's fairly close
to the Lowey Museum specimens waterlines, although I've made changes above
the waterline to improve entry and exit and make rolling easier)is that it
wallows or "corkscrews" in quartering waves. I guess this is caused by the
large amount of bouyancy in the stern, and plan to reduce it in my next
baidarka.
Thanks for your comments.
Regards,
Phil
