About the E20Q

The E20Q is a 20' Endurance series pontoon in Flagship's Quad layout. Flagship groups it under Quad, with an open rear fence.

Flagship lists it with the bi-toon, tri-toon and sport toon packages (bi-toon: 10 persons, 115 H.P. rating; tri-toon: 11 persons, 200 H.P. rating; sport toon: 10 persons, 150 H.P. rating). Capacity and the horsepower rating depend on the package, so they are confirmed for the exact boat.

Other 20' Endurance layouts: E20CU, E20FC, E20LS. Each shares the deck size; the floorplan, seating and published weights differ, so compare the layouts before choosing.

Endurance covers 18 to 22 feet with Cruise, Four-Corner Fish, Quad and L-Seat layouts on the same 25-inch tubes and 8.5-foot deck as every Flagship.
