So I had this idea for capturing ships as new mechanic rather than always just sinking them. It basically would work like king of the hill but rather than having it be like the more people occupying the ship the faster it captures, it would be a steady capture rate per crew regardless if one person or four persons is on board.
So, it would go like this you board a ship and if there is at least one enemy on the ship it won't begin to capture you must either kill them or knock them off. At this point it will start capturing the ship. They will be able to respawn on their ship until it is fully captured. If they respawn or reboard capturing is halted until all of the original crew is of the ship again. If the occupying force is killed or falls off ship all progress is not lost it just starts reversing itself so you have a chance to get back on and continue the capture without having to start over. If a ship is fully captured the original crew will no longer spawn there and they will Spawn with a new ship elsewhere. The ship is now yours and you can choose which to set as your future spawn.
With a good crew you could get yourself a mini fleet going or leave one ship behind. All your ships would show up on the map but if you leave one behind you risk it being captured or sunk. This would open a few varied play styles and would allow a galleon crew to commandeer a sloop and 4 man sloop it if they wanted to. Or rather than sinking an attacking vessel at a fort capture it and have more firepower if they return. Perhaps break up your crew for faster voyages or split your galleon over two sloops for a tactile advantage. Of course spitting a crew and going separate ways to speed voyages up does come with the drawback of increased vulnerability, so you would have to way your options.
Sure there are probably some kinks that need to be worked out with it but it would be an interesting mechanic and add a reason to board a ship more rather than just sinking on sight. Capturing battles could become quite intense especially if one crew just want to sink you while the other is looking to expanded it's fleet.
