Boat Features

The Boston Whaler 315 Conquest is a twin-outboard cruiser-fisherman built on the brand's foam-filled, unsinkable hull, and it suits buyers stepping up from an open boat, center console or tinny who want extended time on the water, overnighting and serious fishing in one package. It carries a fully enclosed head, a galley and a cabin that sleeps up to four full-size adults, plus a wraparound windshield and hardtop that make it a capable harbor day boat and coastal cruiser. Examples among Boston Whaler Conquest boats for sale typically pair fishing hardware with cabin comfort, which is why these boats are often used as tenders to destinations like the Whitsundays. Shoppers searching used Boston Whaler boats for sale will find the 315 Conquest holds condition well thanks to heavy build and abundant stainless steel.

Power comes from twin Mercury Verado outboards, rigged as 250s on some boats and as twin 300s totaling 600 horsepower on others, several with Mercury joystick piloting. Performance runs to a top speed around 38 knots with a comfortable cruise near 27 to 28 knots at about 4,500 rpm; one figure put top speed at 45.8 mph with a most efficient cruise of 1.31 miles per gallon at 26 mph. The fuel tank holds roughly 660 to 670 litres. The deep-V hull, developed for the 315, tracks true and gives a soft, dry ride in 3 to 4 foot seas, with only moderate bow rise on acceleration and a low center of gravity that keeps it settled at rest.

At the helm, full side glass and slim pillars give clear all-around visibility, and the swiveling captain's chair slides fore and aft with a flip-up bolster and dual footrests for seated or standing driving. Electronics range from dual Raymarine HybridTouch displays to twin Garmin 12-inch screens, supported by autopilot, a powerful bow thruster, digital throttle, power-assisted steering, Fusion audio, VHF and a spotlight. A generator (Kohler or Westerbeke) feeds reverse-cycle air conditioning and heating, and the high-quality clears zip out and stow flat in the headliner.

The cockpit measures about seven feet from console to stern and close to nine feet wide, roughly 63 square feet of fishing and entertaining space. Twin insulated fish boxes with macerators sit port and starboard, joined by a livewell, kill tanks, extendable outriggers, multiple rod holders, cockpit refrigeration, a swim shower and a three-step telescopic stainless ladder. A folding stern seat plus optional port pull-out bench and a drop-in table convert it to a dining area. A retractable hardtop sunshade extends aft. The Boston Whaler 315 Conquest T-top boat canvas and Eisenglass package, along with an aft mooring cover that zips under the hardtop, keep the boat protected; a Boston Whaler 315 Conquest T-top boat cover is a sensible add for stored or lift-kept hulls.

Below, a hydraulic high-low table drops to convert the wraparound dinette to a berth, and a wide-open mid-cabin aft berth sleeps two adults at near-queen size. The galley offers a stove top, refrigerator, microwave mounted away from the stove, a pull-out faucet and Corian counter, with a vacuum-flush head and standing headroom. The hull runs over three inches thick, backed by a 10-year hull warranty and three-year component coverage. When weighing Boston Whaler boats for sale, check the bow thruster, generator hours and any aged upholstery on older examples.
