I think I detain the world record now!
A couple of change I think will improve the gameplay.
-Pirates have to be temporized, after a bit, they have to disappear.
-Ability to destroy unused pice(maybe have the 50% refunded).
-More Interactive pice like(Harpoon, some kind of net to catch the fish or trash, steering to turn the boat and maybe an engine system).
-Some sort of "employing a pirate" system, like hire them for some gold and they will go and build for you or recharge the cannon for you.
-More boat pice, to make it prettier.
