It can't be Boaty McBoatface. It's Shippy McShipface

This is a cutaway from behind of a ship and a boat turning port (left)

Ship:

|
|
|
|
|* (center of mass)
|~~~~~~~~~~~~ (waterline)
|<----- normal force as momentum of ship continues forward
|<-----
|<-----

That means the ship's hull is slamming in to the water on its starboard side while turning port, and since the center of mass is above the water, that tilts the whole ship to the right.

Boat:

|
|~~~~~~~~~~~~ (waterline)
|<----- normal force as momentum of boat continues forward
|<-----
|<-----
|<-----
|* (center of mass) <-----
|<-----
|<-----
|<-----

In the boat's case, the hull is slamming into the water on its starboard side while turning port. This can result in a lot of things, but in the general case there's more hull between the center of mass and the waterline than below the center of mass, with the result that the pressure between the center of mass and the waterline leans the boat into the turn.

I feel like I'm still not explaining this well, but I thought the graphic might help.
