SailRange

Expands Valheim's map exploration radius while sailing, using a value controlled by the server.

Features

• 150-meter default boat exploration radius.
• Works for drivers and passengers.
• Leaves on-foot exploration unchanged.
• Unmodded clients can still connect and retain vanilla behavior.
• Matching modded clients receive a locked server value.
• Local-world configuration remains editable.
• One DLL with no companion sync mod.

Install on the server and on clients that want the expanded radius.
