2025 Boston Whaler 405 Conquest

Cruising Boston Harbor just got an upgrade with the 2025 Boston Whaler 405 Conquest, finished in eye-catching Platinum and Black-Chrome Gray. Four powerful Mercury 400 JPO V10 AMS engines provide the muscle for quick trips out to the Boston Harbor Islands or leisurely passes along the Charles River. The Seakeeper SK6 gyroscopic stabilizer ensures smooth sailing, no matter the sea conditions, while the onboard diesel generator guarantees comfort and convenience on longer journeys.

Navigation is effortless and confidence-inspiring. The helm features triple Simrad NSO displays (16", 19", and 24"), a Vessel View Mobile Automatic ID system, Open Array Radar, and FLIR M332 Thermal Night Vision, making foggy mornings or busy marinas near Logan Airport a breeze. The cockpit rear view camera and satellite weather and radio keep you fully aware and connected as you pass by iconic landmarks like the Zakim Bridge or dock in the North End.

On deck, you’ll find luxurious spaces designed for entertaining and relaxing. Enjoy a sheltered conversation thanks to full-height side glass with pop and slide openings, or break out the refreshments at the starboard helm deck wet bar while friends lounge on the foldout bench seat. Mesh windshield shades, a bow sunshade, and a teak aft cockpit table set the scene for summer gatherings, while LED and underwater lighting add drama and safety long after sunset.

Inside, comfort continues with a climate-controlled master stateroom, a modern VacuFlush head and shower, and amenities like a cockpit refrigerator and convenient cooktop. Whether outfitting for an overnight in Marblehead, a spirited afternoon chase past Castle Island, or an impromptu party with the premium audio system cranking your favorite playlist, this 405 Conquest turns everyday trips around Boston into unforgettable cruising adventures.
