Patch Notes: Smoother towns for ship owners

Performance

If you own boats from Come Sail Away, towns no longer lose frames for every boat you've placed, wherever it's moored. A fleet parked in a far-off port used to cost frames even in a town deep inland. Other players' boats near you cost less too.
The sea's helm and broadside panels no longer do work every frame while you're ashore.

SEA-TOWN: a boat's Animators found once a tree shape; the sea's HUDs make no key's name ashore by @Lattymoy in #782
