This 41-foot dual-console cabin cruiser boat absolutely does not compromise when it comes to performance, comfort, and fishability. Enjoy long-distance cruises and overnight stays, chase gamefish far offshore, or host an impromptu gathering—with the 405 Conquest, you never have to choose between gracious comfort and exceptional capability.
