Hi Will,
There is a boat not very far from you on the Colombia river, and I know the owner is planning a circumnavigation of Vancouver Island this year.
His is a centreboard boat and he bought the boat with a modified cabin and has extensively re finished her and she is a lovely boat now.
The owner is a group member, but if he does not see this post I can put you in touch with him.
You won't be sorry if you decide to build a Cape Henry, fantastic boats, and it would be interesting to see a bilge keel version being built. The centreboard does not bother us at all but the bilge keel version would feel much more spacious down below.
Regards
Ron
