Medieval period boats

For my fantasy novel The Wrong Side, I have a scene on a fishing boat. Does anyone know what sort of boats in the medieval period would be suitable for fishing with a crew of 3 (obviously a small boat).

If anyone has any knowledge of controlling sailing boats (and what mistakes a novice could make to sink one) that would also be much apreciated.

Thanks

Well, I know a few different kinds.

A "jolly boat," "dory," or "ship's launch" is a small craft used as
a shuttle between ship and shore. A "ketch" is a small sailing boat
or ship.

I looked up ketch and the wikipedia page has a list of about 100 other sailing vessels, so I'll look through those too. Thanks, I thought no one was going to answer this.

Hey, you're welcome!
