2026 Maritime 189 Defiant

The 2026 Maritime 189 Defiant is an 18.75-foot center console built in fiberglass and powered by a single Yamaha F90LB2 gasoline engine. The boat reaches speeds up to 34.76 knots and cruises at 17.38 knots. This example is finished in Flag Blue with factory options including a 34-inch leaning post with a folding lockable door, stainless steel two-tier stern rail, aft jump seat with removable backrest and arms, and jump seat cushions.

The interior features an all-molded design with seating throughout the cabin, integrated cup holders, and a finished appearance. The deck layout provides ample open space, and custom stainless steel handrails run the length of the boat for safety. The beam of 7.5 feet gives the 189 an open, comfortable feel for its 18-foot length.

The boat includes a custom Tidewater/Maritime torsion axle trailer fitted with LED lights and pivot bunks. Garmin marine electronics are available as an option.
