WHY THIS 285 CONQUEST IS DIFFERENT

Most 285 Conquests reach the market rigged as day boats. This one was optioned as a cruiser. It carries both a factory generator and reverse cycle air conditioning, which is what makes the cabin usable overnight in Florida heat, and few boats this size carry both. It also has the Mercury Joystick Piloting version of the twin 250 package rather than standard steering, so a 9 foot 6 inch beam boat with a hardtop and full enclosure docks on a joystick. Buyers cross shopping 28 foot center consoles should note the Boston Whaler 285 Conquest has a full cabin below with a forward V berth, a mid cabin double berth, a galley and an enclosed head with a door.

SPECIFICATIONS

The 2025 Boston Whaler 285 Conquest measures 27 feet 10 inches LOA on a 9 foot 6 inch beam and draws 20 inches, with 20 degrees of deadrise at the transom. Hull weight is 7,300 pounds without engines, and Boston Whaler lists the boat at 10,181 pounds with engines, fuel and water aboard. Fuel capacity is 200 gallons, fresh water 30 gallons, waste 6.5 gallons, and the livewell holds 26 gallons. Person capacity is 12 and maximum weight capacity is 3,968 pounds. Bridge clearance is 8 feet 10 inches to the hardtop and 9 feet 4 inches with the radar dome and spotlight. Maximum rated horsepower is 500, which the twin 250s meet exactly.

PERFORMANCE

Boston Whaler's factory performance sheet for the 285 Conquest with dual Mercury 250 V8 outboards and 16 by 18 Eco Enertia propellers records top speed of 51.8 mph at 6000 rpm burning 45.2 gph, and 29.0 mph at 3500 rpm burning 16.5 gph for 1.76 mpg, roughly 317 miles of range against the 200 gallon capacity. At 4000 rpm the boat runs 35.0 mph on 20.5 gph. Time to plane is 6.0 seconds. Those numbers were recorded with 96 gallons of fuel, 360 pounds of personnel and 20 pounds of gear aboard. This hull carries the joystick rigged version of that same 250 V8 package, so the factory figures are the right ballpark rather than a measurement of this boat.

ELECTRONICS, FISHING AND COCKPIT

The 2025 Boston Whaler 285 Conquest is fitted with the 16 inch Simrad NSO EVO3S electronics and navigation package, a Simrad HALO24 4kW 24 inch high definition digital radar dome, a thru hull transducer, VHF and satellite radio. Fishing equipment includes radial outriggers, a 26 gallon livewell, in deck fishboxes, cabin rod racks, a stainless steel anchor, a spotlight, underwater LED lighting and 12 volt receptacles at the transom. The cockpit carries a port fold out bench seat, a cockpit table and a cockpit refrigerator.

CABIN, COMFORT AND CANVAS

Below deck the Boston Whaler 285 Conquest sleeps four across a forward V berth dinette and a mid cabin double berth, with a galley and a private enclosed head. Air conditioning is reverse cycle and the generator runs it at anchor. The boat also carries the factory Cabin Comfort and Entertainment packages. Topside it has a hardtop with a platinum underside, a hardtop mounted sun shade, a sun lounge, a helm deck table, black canvas on a white frame and a full glass weather curtain set that encloses the hardtop.

HULL WRAP AND TRAILER

The 2025 Boston Whaler 285 Conquest left the factory in white with chrome graphics and a silver stripe, and the hull has since been custom wrapped. A wrap is reversible, so a buyer who prefers the original white hull can have it back without paint work. A trailer is included. Boston Whaler lists the 285 Conquest on a trailer at 39 feet long, 9 feet 6 inches wide and 12 feet 5 inches high, which is the dimension to check against a garage door, a storage yard height limit or a tow vehicle.

BUYER QUESTIONS

WHAT DOES A BOSTON WHALER 285 CONQUEST DRAW

The Boston Whaler 285 Conquest draws 20 inches. With a 9 foot 6 inch beam and 20 degrees of deadrise at the transom it is deep enough for a Gulf chop and shallow enough to work the Intracoastal Waterway and run the passes.

WHAT DOES THE 285 CONQUEST BURN AT CRUISE AND WHAT IS THE RANGE

Boston Whaler's factory test of the 285 Conquest with dual Mercury 250 V8 outboards shows 29.0 mph at 3500 rpm on 16.5 gph, which is 1.76 mpg and about 317 miles of range against the 200 gallon fuel capacity.

IS THE BOSTON WHALER 285 CONQUEST GOOD OFFSHORE

The 285 Conquest is a 20 degree deadrise hull with 200 gallons of fuel, a hardtop, radar and outriggers, rated for 12 people and 500 horsepower. It is built as an offshore fishing boat with a cabin, and the generator and air conditioning make it an overnight boat rather than a day boat with a berth in it.

WHAT COMES WITH THIS 2025 BOSTON WHALER 285 CONQUEST

This 285 Conquest includes the trailer, generator, reverse cycle air conditioning, the 16 inch Simrad NSO EVO3S navigation package with HALO24 radar, radial outriggers, the full glass weather curtain enclosure, a cockpit refrigerator and the factory Cruising, Premium, Entertainment and Cabin Comfort packages. The original build sheet on this hull totaled $501,396.

HOW DOES THE 285 CONQUEST COMPARE TO A CENTER CONSOLE THE SAME LENGTH

A 28 foot center console gives up the cabin. The Boston Whaler 285 Conquest has a full cabin below with a forward V berth, a mid cabin double berth, a galley and an enclosed head with a door, plus air conditioning and a generator to run it. The tradeoff is walkaround deck space instead of a full fishing perimeter.
