DAMPIER SEA SHACK - TWIN PONTOON HOUSEBOAT / ACCOMMODATION BARGE

12-Berth | Positive Flotation | 2C Survey -Currently in 2C survey through to June 2027, this vessel is ideal for commercial accommodation use, eco-tourism, dive support, charter operations, or as a private offshore sea shack.

To build this vessel from scratch, costs would exceed $1,500,000 plus.

An outstanding opportunity to secure a proven, purpose-built pontoon houseboat designed for comfort, safety and practicality in remote and coastal environments. DAMPIER SEA SHACK is a robust twin-pontoon accommodation barge offering generous sleeping capacity, excellent stability, and genuine "set-and-forget" usability.

Built on six foam-filled sealed poly pontoons per side, with additional aluminium flotation tanks forward and aft, this vessel has a positive flotation design and is widely regarded as unsinkable, supported by a Stability Book. Heavy-duty keels beneath the pontoons allow for safe beaching when required, making this an exceptionally versatile platform for WA conditions.

The accommodation layout is well thought out and highly functional, featuring four cabins each sleeping three, providing comfortable accommodation for up to 12 guests or crew. Amenities include two toilets (including day head) and a dedicated shower block, a large galley, pantry, and a spacious communal area with electrical distribution systems neatly integrated. Please note the photos are from current owners operation and previous owners operation.

A full walk-around companionway runs along the port side and across the bow, enhancing safety and ease of movement. Aft, you'll find a generous alfresco deck area, ideal for relaxing or entertaining, along with a dedicated generator enclosure.

Practicality continues with an aft swim platform and access ramp, allowing easy loading from tenders and dinghies. Larger vessels can safely moor alongside thanks to substantial mooring bitts positioned around the barge. Fuel, freshwater, black water and grey water tanks are all neatly housed within the structural framework beneath the main deck, keeping weight low and protected.

Sustainability is also covered, with 3kW of solar panels mounted atop the accommodation awning to support battery charging and extended off-grid operation.

Currently in 2C survey through to June 2027, this vessel is ideal for commercial accommodation use, eco-tourism, dive support, charter operations, or as a private offshore sea shack.
