After the first sea battle, Gates and Defresne are discussing the net profits that could be expected. Defresne said after injury payments it would be $8 per man. Pirates did actually have a generous disability insurance package. A pirate would get 100 pcs of eight for the loss of an eye or finger, 400 for a left leg, 500 for a left arm or right leg, 600 for a right arm. 1 pcs of eight is worth approximately 0.96 usd in today's money.

In Mosiah's last scene, when Captain Charles Vane reveals himself he lights a cigar with (what sounds like) a Zippo windproof lighter. According to Wikipedia "The first lighters were converted flintlock pistols that used gunpowder. One of the first lighters was invented by the German chemist named Johann Wolfgang Döbereiner in 1823 and was often called Döbereiner's lamp. This lighter worked by passing flammable hydrogen gas, produced within the lighter by a chemical reaction, over a platinum metal catalyst which in turn caused it to ignite and give off a great amount of heat and light." Vane clearly closed a metal lid with a spring and put whatever it was to his side. IF it was a Zippo lighter, the first Zippo was not produced until 1933.
