Avast me hearties! I found an interesting passage ...
"Though the entire crew fought as well as sailed, you would not carry a weapon since most of the important weapons are stored in the ship. Although a belaying pin was an important tool that would be left aboard ship, we will allow you to carry one to further mark you as a sailor. This is a theatrical allowance and is not historically correct.
Those of you who intend to carry weapons, other than your working knives, should make appropriate choices. Pikes, halberds, longarms, and swords would have been in the ship's stores and not privately owned and maintained. Considering the danger of mutiny the same may have applied to daggers, falchions, and pistols. In the later periods there were kept in the captain's custody the length of the voyage. Certain kinds of weapons, such as rapiers and crossbows, were probably left behind.
The weapons carried on the ship would have been unusual in many ways. The pikes would have been "half-pikes," six to nine feet long, and instead of having a sharp steel buttcap, would end in a blunt knob of wood. There is evidence that Drake favored arrows fitted with tamkins (a sort of wad halfway down the shaft) as musket projectiles. While a few of the officers may have carried rapiers, falchions would have been far better suited to the crowded pell-mell combat that boarding usually involved."
