Nope lol. Most of the time a smaller ship will get right next to yours. For me its usually a sloop, and all they would have to do is click on someone on your ship, bring up their menu and hit goto. More often then not, they will keep clicking on you to be friends. In my experience they don't talk, they just start shooting cannons. If you happen to be away from the wheel, they might even take over lol. The people that do ask first, have the manners, and I would allow them on board.
