2026 Boston Whaler 405 Conquest

The 2026 Boston Whaler 405 Conquest is a 40-foot center console built for serious offshore fishing and extended cruising. Powered by four Mercury 400 V10 engines totaling 1,600 horsepower, the boat delivers substantial performance paired with a Seakeeper SK6 gyroscopic stabilizer for enhanced sea-keeping. A bow thruster aids maneuvering in tight spaces.

The helm and cockpit are equipped for both fishing and comfort. Teak flooring runs across the cockpit and helm deck area, with an aft teak table featuring dedicated storage and a starboard foldout bench seat. The helm deck includes a wet bar with a single-burner cooktop and refrigerator. Dual fishboxes with 120V power, a top-loading freezer built into the starboard cabin settee, and a 15-kilowatt diesel generator support extended time on the water. Six blue LED underwater lights mounted on the transom and trim tab pockets provide night visibility. Hardtop-mounted Gemlux 22-foot carbon fiber outriggers offer full rotational and vertical control from inside the helm.

Electronics center on Simrad navigation equipment: dual 19-inch NSO displays, an additional 24-inch NSO display, and a 48-inch Open Array HALO radar with bird detection. An AIS transceiver, satellite weather and radio, and premium audio round out the system. Additional features include full-height side glass with pop and slide openings, a manual bow sunshade, hardtop storage rack, black graphics with boot stripe, white hull with black canvas and frame, and stainless steel trim.
