dont go in your boat just go in the water for a second and then jump out
here's the deal, YOU CAN'T DO THAT. you can sail out to sea on a boat, but you can't swim out to sea.
The only time you dive in on purpose is to follow the instructions of the parrot at Parrot Port. When you jump into the water and return, the parrot has moved to a higher window. (see related question)
