Boston Whaler 405 Conquest Boats For Sale

The Boston Whaler 405 Conquest is the largest model in the Conquest line, a dual-purpose offshore boat built to fish hard and overnight a family of six on extended trips. It measures 41 feet 4 inches length overall, 13 feet 6 inches of beam, and a draft of 2 feet 7 inches, with an empty weight of 24,518 pounds. The hull uses Boston Whaler's two-part construction filled with high-pressure injected closed-cell foam, the unsinkable build the brand is known for, and gelcoat is finished on interior surfaces as well as the exterior so no raw fiberglass shows. Buyers researching Boston Whaler Conquest boats for sale will find it cruises a real-world 35 to 40 miles an hour with the range to reach destinations like the Dry Tortugas for multi-day stays.

Power comes as quad 400-horsepower Mercury outboards or triple 600-horsepower Mercury V12s. With the quad 400 setup, top speed reached 52 mph at 6,100 rpm, best cruise was 32.8 mph at 4,500 rpm burning 52.7 gph for 0.6 mpg, and a range of 336 statute miles off the 600-gallon fuel capacity with a 10% reserve. That rig planed in 4.7 seconds, hit 20 mph in 7.2 seconds and 30 mph in 12.9. The triple V12 600 configuration has shown a peak of 53.3 knots; at 3,700 rpm it holds an easy 27 knots, and a comfortable mid-30s cruise pulls roughly 100 liters per engine. The V12s sit on the center line and steer via rudder angle rather than turning the drives, keeping the boat balanced, and noise levels at cruise are notably low.

The helm carries twin 19-inch Raymarine multifunction displays as an option (16-inch standard) on test, with a companion 24-inch display on the port console so a captain's chart, sounder and radar stay untouched. Recent boats run fully integrated Simrad electronics. Mercury joystick piloting handles docking, and a second joystick hidden in the port dash lets the operator dock port-side-to while looking directly at the cleat through an opening side window. Some boats add a bow thruster and Sky Hook. Two 18,000 BTU air conditioning units and a zip-in rear enclosure can fully isolate and cool the helm deck. The full side windows function as helm doors on both port and starboard, large enough to step straight through to the midship cleats.

The cockpit centers on a large equipment hatch giving access to a Seakeeper 6 gyro, a Fischer Panda generator (15 kW upgrade over the standard 12 kW, required with the gyro), sea-water strainers, battery chargers and bilge pumps. An optional summer kitchen adds a Kenyon grill, sink, Corian counters and refrigeration; skip it and a fold-in bench seat with full bolsters keeps the area fish-centric. A 45-gallon live well, insulated macerated fish boxes, rod holders throughout, and a port dive door with a stowed dive ladder support serious fishing. The forward Sun Lounge converts with adjustable backrests and an infill cushion, and the bow carries 100 meters of galvanized chain on a Quick windlass with a freshwater flush and night lighting.

Belowdecks, headroom exceeds seven feet. A legitimate queen mid-berth, cedar-lined storage, and a settee with a drop-down table create up to three sleeping areas, supported by an optional freezer that extends provisioning range. The dry head separates a porcelain flush toilet from a dedicated shower with a rain fixture. MSRP runs from about $1.2 million for a well-equipped family cruiser to as much as $1.8 million for a boat outfitted with the gyro, tower and full options, making the 405 a capable choice among Boston Whaler Conquest boats for shoppers wanting big-boat range without the size and upkeep of a 50- to 70-foot vessel.
