I like giving boat economy a boost. They're fun to build, but aren't worth anything anymore.
So here's an idea, instead of the boats taking damage and dealing with decay, we go off of the mooring anchor and winds. If the winds are at gale force, let them move a boat a tiny bit every so often. If the boat is moored while a gale is happening then the moor takes an extra tick or 2 of dmg. Eventually the mooring anchors would break and the boat would be set free to move with strong winds. As more time passes these loose boats may even find their way to the server border at which time they cross to chaos.
Makes anchors more important, would add openings to the boat market, also adds some more immersion by seeing boats slowing moving across servers if abandoned, and it would give chaos players new toys to abuse.
