Custom Larson Boathouse

1985 Custom Built Larson Boathouse – Exceptional Yacht Shelter with Loft Conversion Potential
Located on the Multnomah Channel in Scappoose, Oregon

This custom-built boathouse is designed to provide maximum protection for your valuable yacht while offering the flexibility to add comfortable living or work space above. Constructed in 1985 and built to commercial-grade standards, the structure features a spacious 26’ x 116’ boatwell, oversized 28’ x 30’ electric roll-up door, and heavy-duty steel frame construction.

A large 22’ x 40’ mezzanine, accessed by a steel staircase, is ideal for storage but can easily be converted into a loft-style living area — perfect for weekend stays, full-time use, or an office/workshop setup right on the water. Whether you’re storing a cruiser, sport yacht, or classic vessel, this boathouse offers serious protection from the Northwest’s wind, rain, and sun.

The float is constructed with concrete decking over foam for long-lasting, low-maintenance durability. Insulated steel siding and roof provide added climate control and year-round usability.

Currently moored on the scenic Multnomah Channel in Scappoose, Oregon, the boathouse is available with a long-term lease in its current location or can be relocated if desired.
