2026 Boston Whaler 405 Conquest

The 405 Conquest is a 41-foot fiberglass walkaround built for extended cruising and offshore capability. Powered by four Mercury Verado engines delivering 1,200 horsepower combined, the boat balances strong performance with versatile accommodation. A full-beam single-piece windshield provides unobstructed sightlines, with optional side glass available for enhanced views and connection to the water.

Below deck, the cabin includes a private master stateroom, two guest sleeping quarters, an enclosed head with separate shower, and a galley. The design prioritizes comfort for overnight voyages and longer journeys, with luxury details including a rain shower, innerspring mattresses, and Corian countertops throughout. Interior finishes and materials reflect the boat's sophisticated approach to cruising comfort.

The layout emphasizes social and functional flexibility. A portside companion lounge features a hidden table with multiple positioning options, while the transom area is fully customizable to support fishing or entertaining needs. The helm companion zone integrates easily into the overall deck flow. Joystick Piloting is available as an option to simplify handling.

Optional equipment includes side glass extensions for the windshield and a Seakeeper gyro-stabilizing system for enhanced ride quality in varied sea conditions.
