Merchant Ship - Has 2 sails. Has a 3-4 Person Crew. Has extra space for animals and chests because it is suited for quests. The ship would be equipped with only two canons because it is not suited for war. Extra space for supplies like 2 barrels of 100 bananas, 2 barrels of 100 wooden planks, and 4 cannonball barrels. The ship size would be in between the size of a sloop and a Galleon.
Warship - Four sails. 4 - 6 Person crew. Has 5 canons on either side of the ship, 4 canons on the front and back. Turn rate is very slow. 2 cannonball barrels on deck for easy access to cannonballs. Same amount of barrels below deck for storing supplies. The ship size would be considerably larger then the galleon.
Attack Ship - Has 2 sails. 1 - 3 Person crew. Equipped with raid ship on the side of the boat (See next ship idea) 2 canons on either side and 2 on front and back. The ship is a little larger then sloop.
Raid Ship - Placed on side of Attack ship with its own ladder to get to it. It can fit 1 - 2 people equipped with 3 boxes for supplies. (Can fit 15 of each inside) Has one canon on the front. The front seat would control the canon and the back seat would row the boat. As big as a life boat. Fast and small turn radius. Can dock on enemy ship with boarding ladder. The purpose is to raid enemy ships of supplies and do a little amount of damage.
