Potential crew abilities-
The ones from the Ares website work really well I believe, they are-
Good Aim-When firing a broadside, and opponet draws one or more "0s", you may use this ability to make them draw an additional counter (may be used twice)
Well-trained gunners- Single broadside may be reloaded after it has fired (may be used once)
Elite Marines- When shooting muskets, if a "0" damage counter is drawn, you may force the opponent to draw an additional counter (may be used once)
Hold Fast- Ship has one free crew damage box left to take a crew hit in, the ship may take an additional three crew hits before surrendering
Skilled Quartermaster- May increase Veer by 1 for duration o the turn (may be used twice)

In addition other crew abilities could be Fast repair, Fast fire fighting, skilled pumping, Rifle-equipped marines, and Skilled boarders
