Boston Whaler 365 Conquest Review: A Premium Sportfish Cruiser

The Boston Whaler 365 Conquest is designed for boaters seeking a vessel that can handle both offshore fishing and comfortable cruising. With its robust construction and thoughtful layout, it caters to those who value a versatile boat. The thoughtful design is particularly apparent in its point-of-use storage and controls, making it friendly to occasional crew as well as the owner. 

Our review includes commentary from content partner BoatTest.com, whose Captain Trip conducted this video test of the 365 Conquest and said, among other things, “I can just see myself being on this boat for multiple days, maybe coming down the East Coast or headed to the Bahamas…. And those long days will be very comfortable on this boat.”


Key Features of the Boston Whaler 365 Conquest

The cockpit measures 115 by 66 inches, providing ample space for fishing activities. It includes a 52-inch-long fish box, a 19-gallon pressurized livewell, and a dive door with a flip-out boarding step. Storage solutions are integrated throughout, including dedicated spots for a five-gallon bucket and fishing gear.

For those intent on maximizing entertainment value, an optional summer kitchen across 70 inches of the transom features an electric grill, sink, cutting board, and pull-out refrigerator. Optional outdoor dining can be set up by flipping down a port-side bench seat and installing a table from its storage area in the engine access panel. An optional cockpit sunshade provides further protection. Note that some of this entertainment package removes reel racks and other fishing-specific gear.

For navigators, the helm is equipped with dual 16-inch Simrad displays, a joystick for docking, and controls for the two Mercury engines, plus an adjustable captain’s chair and nearby air conditioning vents. Captain Trip noted how the most essential controls while underway are easily reachable—no need to reach forward for windshield wipers, horn, or autopilot controls. Convertible seating provides a second forward-facing bench seat at the port display. The station can be enclosed in glass for better climate control, and an optional flybridge with joystick control can be added for enhanced visibility and control when fishing. 

Below deck, the cabin has a generous 6’9” inches of headroom at the entrance, decreasing to 6’5” forward. The U-shaped dinette converts to an island berth with the push of a button. Additional sleeping space is available in the aft berth, measuring 78” by 52”. To port, buyers can choose between a 72” couch as potential extra sleeping space or a seat and 36” galley, complete with microwave. The head includes an electric flush toilet, sink, and separate shower with a teak bench seat. Throughout the cabin, Boston Whaler includes special touches such as a cushion that reverses to a small table with cupholders.

Performance

In its review, BoatTest.com cited Boston Whaler’s sea trial data with the twin Mercury 600 HP V12 Verado engine option. The 365 Conquest achieved a top speed of 53.1 mph at 6,400 rpm. Optimal cruising occurred at 5,000 rpm, delivering 41.6 mph and approximately 0.8 mpg, for a range of about 281 miles with a 10 percent fuel reserve. Acceleration from idle to 30 mph took 8.9 seconds. The 365 Conquest also has the option for triple Mercury 400 HP V10 engines. 

Capt. Trip summed up the 365 Conquest’s performance saying it “isn’t a sport boat. You're not going to get up on plane and run really, really quickly, and it's not going to react super quickly …but it still is nimble."

 

Boston Whaler 365 Conquest Pricing

The 365 Conquest was introduced in 2024, and a year later most listings remain for new boats with price on application (POA). Interested parties can expect pricing to start around $1.1 million, with total cost based on selected options and engines.

Pilothouse

Conclusion

The Boston Whaler 365 Conquest stands out as a versatile vessel capable of handling both serious fishing trips and comfortable cruising. Its combination of practical features and innovative design makes it a good choice for those seeking a premium-level multi-purpose boat built to excel in smooth water and rough seas.
