After sailing a certain distance of meters, Barnacles. Marine growth and Seaweed should start to accumulate on the ship.
Ladders could be slippery as well as parts of the top deck. Let the sea matter build up too much and the ladders will be inaccessible.
On parts of the top deck, you will be more likely to slip overboard.
A push broom could be created to help keep things clean and tidy.
Maybe if you're a pro Pirate crew you'll let the green slimy gunk build up, a deter to would be tuckers/boarders.
If not added to the ships, it would still be cool to see large patches of seaweed around each island's shallows. If you pull your boat into it unaware, your boat will take longer to turn or sail out of.
When swimming through the seaweed, you'll be slowed down and blinded like the plants blind. You could then be able to grab a bucket of the matter and blind others similar to the puke effect.
Either way, I would love to see more marine life of some sorts that's interactive and not just visual.
Hope all you Pirates are having a good week, CHEERS!
