I bought this boat from someone and took it out for the first time today and the left hull stayed absolutely dry, but I ended up sailing about to miles to shore with the right hull entirely submerged. When I got it on shore, water was leaking out of where the cap for a hull port goes on. It''s one of those twist and lock ones from Rabud Inc. That''s the only spot where water was coming in from, and after about 30 minutes on the water, that hull was filled to the top. It''s not leaking from around the outside lip of the entire port, but just from around the cap that locks into it. Is there supposed to be an O-Ring in there or something??? If a missing O-Ring isn''t the problem, then I don''t see how the heck that thing is supposed to be water tight.
