About the E20CU

The E20CU is a 20' Endurance series pontoon in Flagship's Cruise layout. Flagship groups it under Cruise: lounge seating wrapped around the deck for socializing and cruising.

Flagship lists it with the bi-toon, tri-toon and sport toon packages (bi-toon: 10 persons, 115 H.P. rating; tri-toon: 10 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: E20FC, E20LS, E20Q. 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.

Not shown: power versus manual Bimini (the 2026 brochure lists a power Bimini; the series page says Bimini top); the stereo brand (the series page names Impact Audio, the 2026 brochure Kicker); weights, capacities and fuel units (Flagship's sheet prints the figures without units); model year (Flagship's specification sheet states none). The manufacturer's published sources disagree or do not state these, so we confirm them from the model documentation on request.
