Thank you for your info. The boot seems particularly useful, but I haven’t been able to find them online. If you have any sources, I’d be grateful. Since I posted the original message I’ve learned that Seahawk makes a “Seahawk Sport 400” and a “Seahawk400.” They are not the same boat. The Seahawk400 is a cheaper AND less expensive boat than the Seahawk Sport 400. Let the buyer beware, I guess.
I’d also appreciate any other advise from anyone else who has experience with the Seahawk Sport 400. I think the more info I can get, the better.
