Oregon has Floating Home laws, but a floating home is different from a boat as it typically requires fixed installed sewage systems and subject to building codes and they don't sail, whereas boats, well they are boats.
“Floating home” has the meaning given that term in ORS 830.700 (Definitions for ORS 830.060 to 830.140 and 830.700 to 830.870). “Floating home” includes an accessory building or structure.
