MarineMax Yachts is proud to present MA BELLE, an exceptionally well-equipped, like-new 2025 Boston Whaler 405 Conquest, powered by quad Mercury V10 400 Verado outboards.

The Boston Whaler 405 Conquest is the flagship of Whaler’s Conquest lineup, combining serious offshore capability with the comfort, accommodations, and amenities of a luxury cruising yacht. At over 40 feet, the 405 offers an impressive amount of usable space, including a climate-controlled pilothouse, spacious cockpit, well-appointed cabin, full galley, overnight accommodations, and multiple entertaining areas. Whether the goal is offshore fishing, extended cruising, entertaining family and friends, or spending weekends aboard, the 405 Conquest is designed to do it all while delivering the unsinkable construction and quality Boston Whaler is known for.

MA BELLE has just over 63 hours and shows like new. In addition to an extensive factory option list, the current owner has made several significant upgrades that separate this 405 from others on the market, including FLIR night vision, Starlink connectivity, and a Platinum Marine Service Protection Plan covering eligible boat components through 06/24/2033. This provides the next owner with an exceptional level of coverage and peace of mind for years to come.
