In general, pirates greatly preferred weapons that only lightly damaged or temporarily disabled the attacked ship but wreaked havoc among its crew. This was because the pirates frequently shifted
into the prize ship which was often a larger vessel in much better condition.
In the warm waters of the Caribbean the hull of a ship began to leak after only a few months. Shells attached themselves to the hull and slowed the ship down which could not have been very welcome to
the pirates who mainly relied on speed to catch their prey or evade their hunters. Since they had no dockyards they had to beech the ship on a remote island to repair it and hope that no warship came by.
