Overview
The Boston Whaler 405 Conquest is the largest model in the Conquest lineup, designed as a versatile vessel capable of offshore fishing as well as extended family vacations for up to six people. It combines spaciousness with performance, embodying the brand's signature styling and reliable handling characteristics.
Dimensions and Weight
The 405 Conquest measures 41 feet 4 inches in length overall, with a beam of 13 feet 6 inches and a draft of 2 feet 7 inches. The boat's empty weight is 24,518 pounds. During testing, with 450 gallons of fuel, 90 gallons of water, 35 gallons of diesel for the generator, three people, and test equipment aboard, the estimated test weight was 31,622 pounds.
Power and Performance
The test boat was equipped with four Mercury supercharged 400 horsepower four-stroke outboard engines. At full throttle of 6,100 RPM, the 405 Conquest reached a top speed of 52 miles per hour. The most efficient cruise speed was found at 4,500 RPM, where the boat traveled at 32.8 miles per hour while consuming 52.7 gallons of fuel per hour, resulting in approximately 0.6 miles per gallon and a range of 336 statute miles with 10% of the 600-gallon fuel capacity reserved. The minimum planning speed was 12.6 miles per hour. At idle speeds of 600 and 1,000 RPM, the boat moved at 3.6 and 6 miles per hour respectively, with fuel consumption rates of 2.5 and 4.4 gallons per hour, maintaining a fuel efficiency rating of 1.4 miles per gallon. Acceleration tests showed the boat planed in 4.7 seconds, reached 20 miles per hour in 7.2 seconds, and 30 miles per hour in 12.9 seconds. Maneuverability was excellent, with the vessel handling wakes and tight turns with agility uncommon for its size. Docking was facilitated by a port-side joystick and an opening side door.
Helm and Controls
The helm console is well-equipped and thoughtfully designed. At the top are USB and auxiliary inputs, 12-volt power outlets, and an inductive charger for mobile phones. The test boat featured optional twin 19-inch Raymarine multifunction displays, while the standard configuration includes 16-inch units. Accessory switches and air conditioning vents are positioned above the tilt stainless steel steering wheel, which aligns with a compass. To the left of the wheel are controls for the Fusion Apollo stereo, Mercury Vessel View display, and spotlight. The right side houses ignition and trim tab buttons, with digital shift and throttle controls and the Mercury joystick piloting system located just aft. The helm benefits from optional full-side windows with an opening section, allowing the operator to view the boat's side, operate the joystick, and reach cleats for docking lines. The port console includes a companion station with a 24-inch multifunction display and a hidden second joystick for port-side docking. Additional power outlets and phone chargers are also integrated into the port console.
Exterior Features and Deck Layout
Side passageways are equipped with stainless steel rails for safety and ease of movement. The foredeck features a Lumar windlass with a 10-inch cleat for securing the anchor rode, pull-up cleats on each side, and sockets for a bow shade. Access to the anchor locker is conveniently located alongside the windlass. The stern area includes a starboard transom door providing easy access, a narrow walkway forward of the splash well, and small swim platforms on both sides. A four-step ladder is stored in a dedicated locker on the starboard side. Motor rigging is cleanly arranged with inspection hatches forward of each engine. Below decks, the main distribution panel is accessible within the cabin, and mechanical equipment is reachable via a large in-deck hatch in the center of the cockpit. This compartment houses a 15kW Fisher Panda generator—an upgrade from the standard 12kW unit—paired with a SeaKeeper 6 gyro stabilizer. Fuel water separators and battery chargers are positioned outboard to starboard, with strainers and bilge pumps located forward of the generator.
