... Well, I did some testing with the remodeling on ships...

If the ship has 2 or more remodels, the moment you buy a second remodel, you get ANOTHER ship. For free(well, other than the cost of gold, but still). It loses all the stats of the original ship, but you can have BOTH remodels without having to swap between them.
