Some neat customs! I do like some of the implications of those Ex-Patriot crew. Erickson might see usage on a ship with Dories or a Hoist.
Rynah seems like a really extreme fort. She has a high gold cost to match, but it will be interesting to see if it might be broken despite that. It would be the ultimate game extender in 2 player games, because an opponent is extremely unlikely to be able to destroy it. (making it harder to reach a gold endgame condition)
