I would like to be able to trade ships between Pirates on our own account. This would make it more likely that I will buy at least one ship at each level from the Crown Shop if I could use it with more than 1 Pirate. As it stands now, I am very unlikely to buy a ship from the Crown Shop unless it is on sale for 50% of the normal Crown Price and, even then, I will be very picky about what ships I buy.
