I typed this up as a progression response, but I think it deserves it's own thread. Please add your ideas.
Ramming prow: Remove the front sail of your galleon to install a reinforced ramming prow. Significantly reduces top speed. 3650 gold. (Major hull change)
Armor plating: Each of the 32 armor plates bounce one cannonball before being knocked off into the sea. The increased weight will slow your ship and sink you faster. 2860 gold. Full refit only. (Add-on)
Chase cannon: Install one cannon facing forward in the prow of your ship. Cannon explodes dangerously if shot directly. 5200 gold. (Add-on)
Coward's cannon: Install two cannon facing aft in the stern of your ship. Cannon explodes dangerously if shot directly. 8800 gold. (Add-on)
Jib sails: Fore and aft rigged triangular jib sails. Increases top speed, especially in crosswinds. Not compatible with ramming prow. Temporarily blinds the helm if shot loose. 4380 gold. (Add-on)
Geared capstan: Dramatically increase the speed of lowering and raising the anchor. Anchor is lost at sea if capstan destroyed by cannon fire. Requires repair in port. 1620 gold. (Add-on)
Extra-large rudder: Turning speed increased. Draft depth increased. Can be destroyed by dragging or cannon fire. Unable to turn for fifteen seconds while wreckage breaks loose before returning to original turn speed. 1250 gold. (Add-on)
Cannon turrets: Install four cannon turret towers at the corners of your ship. Significantly reduces speed, turning ability, and visibility from helm. 16820 gold. (Major hull change)
Harpoons: Replace two cannons per broadside with a single harpoon cannon. Enemy ships harpooned must chop the barbed spear loose or remain tethered to their foe. Rope can be cranked in to reduce distance slowly. 9810 gold. (Major hull change)
Longboat: Hang a longboat for shore parties or boarding actions from the stern of your ship. Must be repurchased if sunk. 3460 gold. (Add-on)
Chum buckets: Hang four chum buckets from the sides of your ship. Increases shark activity when dumped. Full refills only. 780 gold. (Add-on)
Gunpowder barrel drop: Comes stocked with three barrels to drop over the stern of the ship. Refillable by hand. Explodes dangerously if shot. Not compatible with coward's cannon. 2890 gold. (Add-on)
(All add-ons can be destroyed by cannon fire and must be replaced at full cost or removed in port. Major hull changes such as the ramming prow cannot be destroyed at sea, but can be sold or swapped out at port.)
