Boston Whaler Realm Boats For Sale

The Boston Whaler Realm series adapts the brand's offshore center console into a cabin cruiser built around entertaining, and it comes in two sizes: the 350 Realm and the larger 380 Realm. The 350 Realm carries a length overall of 35 feet 6 inches, a 10-foot 10-inch beam, a 24.5-inch draft, and a 14-person capacity, while the 380 Realm stretches to 38 feet with an 11-foot 8-inch beam. Both keep the deep-V offshore hull and foam-filled construction that give Boston Whaler boats for sale their reputation for a stable, quiet ride, but the Realm layout trades dual side decks for a wide bow seating lounge, a conditioned helm area, and a fishing-capable rear cockpit.

Performance numbers depend heavily on the engine choice. A 350 Realm on triple Mercury 400 V10 outboards with 18x22 Rev4 props reached a top speed of 57.6 mph at 6,200 RPM, with best cruise at 3,500 RPM returning 28.2 mph; it hit 30 mph from a standstill in 7.2 seconds. The 350 carries 365 gallons of fuel, 45 gallons of fresh water, and a 10-gallon waste tank, with a dry weight of 13,600 lb. The 380 Realm offers standard quad Mercury 300s, optional quad 400s, or twin Verado 600 V12s; on the twin 600s it ran 56.9 mph at 6,335 RPM and cruised at 38.8 mph at 4,500 RPM, with the quad V10 400 package producing 1,600 horsepower from 22.8 liters. The 350 is rated to 1,200 horsepower maximum, and some owners have fitted triple Mercury 425s.

The helm runs digital. The 350 Realm uses dual 16-inch Simrad displays, the 380 adds a third 16-inch screen, and both integrate lighting, audio, and navigation into the Simrad interface so the dash carries only a handful of physical switches. Joystick piloting with autopilot, trim tab controls, JL Audio controls, Seakeeper stabilization with a dash display, and a Simrad VHF are standard equipment, and the 350 helm pad sits about 6 inches elevated for visibility. A vent window in the wraparound windshield and air-conditioning vents let the helm area be enclosed with Isinglass for heating or cooling.

The cockpit is set up to switch between fishing and entertaining. The 350 Realm has a 15-gallon livewell, two large fish boxes including a starboard chiller box, a 28-inch cockpit depth, three transom rod holders, a Kenyon electric grill, and a side dive door with a stowed dive ladder. The 380 adds a 260-quart chiller, a standard summer kitchen with an optional livewell, and a custom-hinged dive door. Both boats put folding cockpit seats, a teak tow rail with shelf, a solid transom door, a hot-and-cold freshwater shower, and stowage for dual teak tables under a cockpit hatch. The bow lounge on both seats multiple guests with armrest cup holders and a pop-up sunshade.

Below, the cabin suits one- or two-night stays. The 350 Realm has a wet head with a plumbed porcelain toilet and flip-down teak seat, a convertible berth, a skylight, a TV, and RGB lighting. The 380 Realm steps up to a fully enclosed head with standup headroom and a vacuum-flush toilet, a galley with sink and refrigerator, a cedar-lined hanging locker, and a convertible V-berth. At a 2026 boat show, a 350 Realm on triple Mercury 425s was priced at $922,305, placing the Realm among Boston Whaler's premium do-it-all offerings.
