I use lesser ship equipment cause I like how it looks, which in turns makes it more fun to play with. Problem with that is that the lesser ship equipment isn't nearly as good. I'd like to be able to stitch.
It would be nice to be able to use the cool-looking stuff well after your ship has progressed beyond that point. I expect, though, that it'd be kind of hard to make stuff stitch-able, with the different origins and so forth with some of this gear.
I kind of wish we could buy a max-level raft and appropriate gear for it though.
When the game first launched, ship equipment was even MORE limited to work with, as most pieces only fit skiffs, or frigates, or galleons of each world origin, and they bowed to player pressure that it be more flexible. Now we are only limited by the world Origin and our level.
Stitching equipment within the ship Origin guideline would be great - especially for Figureheads. Those really give a ship its personality.
