Boston Whaler balances its 60-year tradition of building unsinkable hulls with its ongoing refinement of boats built on those hulls.

The Boston Whaler brand encompasses seven distinct lines.

Super Sports are peppy load-and-go funsters. Montauks are classic, ever-popular center-consoles 15 to 21 feet. Dauntless models balance watersports and coastal fishing.

Vantage dual-console boats aim first at family-friendliness. The Conquest family has fishing-focused offshore boats with all the comforts of home. Realm 35- and 38-footers blend center-console fishability with cabin-cruiser comfort. And Boston Whaler Outrage boats are battle-ready offshore-fishing machines.

Second among primary-boat brands owned by our survey respondents, and among those most numerous of second and third boats owned by those respondents, Boston Whaler is also one of the top two brands respondents would consider for their next purchase.

The big cruiser’s cabin contains a master berth with inner-spring mattress, plus a midcabin guest berth, teak cabinets and flooring, enclosed head with separate shower, and galley with cooktop, microwave, refrigerator/freezer, storage—and even lighted wineglass holders.

The angler is served by a transom prep area and a 19-gallon pressurized, lighted, insulated aft livewell. (Of walkaround respondents, 85 percent said they need just a single bait tank.)

The 405 has five gunwale-mounted cockpit rod holders —34 percent of walkaround survey respondents say they’re OK with four; another 46 percent would like six. Five more rod holders line the transom, six more on the hardtop supports. The 405 is also set up for outriggers and/or downriggers.

The stern bench folds away to add fishing space, the setup 48 percent of walkaround survey respondents prefer. Other seats are convertible, facing front or aft.

Optional on the 405 Conquest is Seakeeper gyrostabilizing, which 24 percent of prospective walkaround boat buyers said they’d consider.
