Lake Roosevelt Adventures is a boat rental and moorage operator based in Davenport, Washington, serving Lake Roosevelt from two marinas: Seven Bays Marina and Keller Ferry Marina. The company offers a fleet of Princecraft 22-foot pontoons powered by 115hp Mercury motors that accommodate up to 12 people, and Triumph 186 ski boats — 20-foot vessels with 150hp Mercury motors that seat up to seven guests.
Pontoons are available at both Seven Bays Marina and Keller Ferry Marina, while ski boats are offered at each marina for watersports and cruising. Transient moorage reservations are available at both marinas with slip sizes including 20ft, 25ft, 26ft, and 30ft depending on location. Night-length moorage options include five, six, seven, nine, ten, and thirteen night reservations. Reservations list check-in times after noon and check-out or departure by noon on final day when specified. Moorage slips are described as open coverage without power or water.
All vessel specifications and moorage details reflect the listings for Lake Roosevelt Adventures: vessel lengths, motor horsepower, passenger capacities, marina names, slip sizes, and reservation durations. Interested customers can choose boat rentals for groups, watersports, or leisure cruising, or select transient moorage to base longer stays on the lake. Policies such as slip coverage and check-in windows are stated per marina listings. The listings provide clear information for planning safe and compliant visits to Lake Roosevelt via the two marina locations.
