Boat Add-on

[kadapunny]

Hiya, I just had two dreams about boats
and that got me thinking
What if there was generated structures of sunken boats that could appear from time to time?
To get them afloat, there's a sign on them, and if you click it, they float up to the sea. Then the sign turns into the regular signs for boats, except one sign says how rare the boat is.
Of course, I'm thinking to make boat making for only admins, since somebody can do /boat sell
And with that, they use /boat sell, and then right click on the sign of a boat that tells them what boat it is, and then after selling the boat, all signs disappear (not the boat)
Oh and also player NPCs
