I agree. Not something to be taken on board with inexperienced players or if you are doing a really large battle. It is very easy to lose track of what is transpiring on every ship and spoils the flow of the game with housekeeping. One solution is that I use is to assume that crew can handle any action until you are down to half crew. After all the ships Officers are there to direct the men. Then they can only do the actions they have men for ans as officers fall it gets harder to direct the men.
