2026 Boston Whaler 405 Conquest

The 2026 Boston Whaler 405 Conquest is a 40-foot center console built on unsinkable fiberglass construction with striking white hull and black boot stripe graphics. Four Mercury 425 JPO V10 engines deliver 1,700 combined horsepower, supported by a bow thruster, anchor windlass with chain, and a gyroscopic Seakeeper SK6 stabilizer for offshore confidence and control. A 15kW diesel generator provides independent power for extended cruising.

Navigation and safety systems include dual Simrad 19-inch displays plus a 24-inch NSO screen, a Simrad Open Array Halo 48-inch radar with Bird+ and AIS, a FLIR 30Hz M332 thermal night vision camera, and cockpit rear-view camera. Satellite internet and full vessel monitoring round out the electronics suite, complemented by premium audio throughout.

The boat showcases rich teak interiors and flexible entertaining spaces. The cockpit features solid teak flooring and tables with dedicated storage, a starboard foldout bench, and an electric hardtop sunroof. Full side glass enclosure with pop-and-slide openings and mesh shades creates weather-protected deck space. Dual fishbox chillers, cockpit refrigerator, top-loading freezer, and helm deck cooktop support extended time offshore. A single head completes the accommodations.
