Ever feel screwed by ships who just keep on fleeing for hours and you are unable to catch up because the ships are the same?
Have no fear, I have the solution for this.
A weight system. The more supplies / crates / loot / skulls you have on your ship the heavier you become as a ship, the slower you will become.
This is pretty much a critical implementation because I am getting sick and tired ( and everyone else) if the only way to catch a ship is with it's pants down when it is anchored near a island... Everybody has figured out the the sailing system by now and there is no advantage to be gained once both ships are chasing. Galleons just go with the wind if they are being chased by a sloop, and sloops just sail against the wind when being chased by galleons... GG
