what to do with the extra cash?

[The Skirata Clan]

I need suggestions as to where to spend all your loot once you reach the max and can't buy more clothes, ships, ammo, and tattoos.
I remember back in the linked-accounts days one could just transfer the money to another one of your pirates with the poker system. But now that is no longer possible.

What should we be able to buy? Should we be able to buy skill points? I mean, even if you fully master now you won't be able to max all abilities in the weapon. We get 55 skill slots to fill per Skill (sailing, cannons, weapons). Out of those 55, we only have a chance to get 31 once fully mastered. We have 24 open slots per Skill. Wouldn't it be great to purchase a skill point for, I don't know, 10k. Even 5k is a reasonable price to buy them, and it will promote sailing to get those amounts of cash.
