Boattest.com Review
Overview
The Boston Whaler 315 Conquest is a versatile offshore fishing boat that also appeals to cruising couples due to its excellent seakeeping abilities, weather protection, and comfortable accommodations below deck. This model serves as a crossover platform, balancing the needs of both fishing enthusiasts and recreational cruisers. The following review provides a detailed assessment of the 315 Conquest’s design, features, and performance based on a full test conducted by BoatTest.com.
Exterior Design and Deck Layout
Boarding the 315 Conquest can be done either from the swim platform via the aft cockpit door or from a fixed pier using the 11-inch wide cab rails. The center deck hatch lifts to reveal a mechanical space housing a 300-gallon aluminum fuel tank, engine start and house batteries, bilge pumps, macerator pumps, a high-water alarm float, and an optional 7kW generator. The helm benefits from an all-glass windshield with narrow mullions, providing distortion-free sightlines and integrating seamlessly with the hardtop. Additional features include pantograph windshield wipers with integral washers and an electrically actuated vent at the windshield’s top for ventilation. The helm seat is ergonomically designed with polished cast-iron rests, a flip-up bolster, and the ability to swivel and slide, accommodating both seated and standing operation. The cockpit features hardtop ladders with rocket launchers, facilitating easy access to the side decks, which measure a generous 14.5 inches in width. A lengthy grab rail mounted to the hardtop aids movement to and from the bow. The bow area is equipped with a standard anchor windlass, stainless steel anchor roller, a hatch for rode storage, and a windlass remote. Ten-inch cleats are positioned outside the tow rails to prevent chafing, and the bow rail height measures 25 inches, ensuring safety during work at the bow.
Power and Performance
The 315 Conquest measures 31 feet 3 inches in length overall, with a beam of 10 feet 8 inches and a draft of 20 inches. Its deep V-hull features a 20-degree dead rise at the transom, contributing to its excellent seakeeping characteristics. The hull weight is 8,800 pounds, and with three-quarters fuel, two people aboard, and optional twin 300-horsepower Mercury Verado engines, the test weight was 11,426 pounds. The twin Verados propelled the boat to a top speed of 47.5 miles per hour at 6,100 RPM, consuming 60 gallons per hour and providing a range of approximately 207 miles. The most efficient cruise speed was recorded at 33.2 miles per hour at 4,500 RPM, with a fuel burn of 24.55 gallons per hour, extending the range to 354 statute miles. The boat demonstrated a quick planing time of 4.2 seconds, reached 20 miles per hour in 5.6 seconds, and accelerated to 30 miles per hour in 9.5 seconds. During testing in moderate offshore swells, the 315 showed excellent wave penetration, effectively throwing spray to the sides and maintaining a dry ride. The boat exhibited a 13-degree bow rise upon acceleration, settling into a 5-degree bow-high attitude at cruise, and a maximum bank angle of 10 degrees during full-power turns. Deceleration resulted in a slight stern-first settling without compromising forward visibility, underscoring the boat’s stable and predictable handling.
Conclusion
The Boston Whaler 315 Conquest is a well-executed crossover vessel that satisfies the demands of both serious fishermen and cruising families. Its thoughtful design, robust construction, and impressive performance characteristics combine to create a boat that is enjoyable to operate and capable in a variety of conditions. The 315’s blend of offshore capability, comfort, and versatility makes it a compelling choice for those seeking a multi-purpose boat. This comprehensive test confirms Boston Whaler’s success in delivering a platform that balances fishing functionality with cruising amenities.
