Since becoming a subsidiary of Brunswick Marine, Boston Whaler has had the resources to expand its lineup of motorboats dramatically. Today, Whaler offers five major lines and in those lines they offer a total of 25 different models. For example, Whalers Montauk line their second lineup consists of four models, the Montauk 150, Montauk 170, Montauk 190 and the Montauk 210.Actually, Whaler couldnt offer the number of models of its unsinkable motorboats were it not for the resources of Brunswick Marine. Indeed, Brunswick also provides the powerplants for most of its motorboats either outboard or sterndrive through its Mercury or MerCruiser engine division. Brunswick purchased the engine business from Mercury Motors when they were divesting themselves of anything not car-related and while they did make a good engine, it was diverting money from the cash they needed to make new model cars. So, for Brunswick and Mercury, it was a match made in Dearborn and on the water.With all that said, lets look at the Montauk line beginning with the 150.Whaler Montauk 150If there was an heir to the classic look of the Boston Whaler (yes, you can argue that the Sport line is also an heir to the look), it is the Montauk 150 with its Whaler body tub and Unibond construction technique that yields an unsinkable boat. Indeed, the word unsinkable was the word that drew the boating world to the Whaler line in the 1960s when they were the only line to build boats out of the then-new plastics with air-filled pockets.The Montauk 150 has the classic Whaler center helm and center acrylic windscreen for the skipper. Like the original Whaler, the Montauk 150 offers a reversible seat that, with the back in one position, acts as a seat for the skipper and two friends (its a bench). The seatback can be reversed and locked into a rearward-facing position so that the six passengers the 150 can carry can have a nice conversation or picnic lunch.The 150 features an interesting bow anchor/stowage compartment and extra stowage on the sides. Shes 15.5 feet and has a 6.6-foot beam. Interestingly, she only draws seven inches of water which means that if you pull the outboard up and out of the water you can anchor in some interesting areas either to pull your boat out of the water for trailering home or if you are just sitting having lunch waiting for the tide to turn and any fish that might have run in close to shore for protection will now have to head out again and you can follow them.The standard engine is a Mercury 60-horsepower four-stroke, although she can also run all day long with a 40-horsepower engine.Whaler Montauk 170The 17-foot Montauk 170 is another of the heirloom Whalers that look like the early motorboats once looked.The key here, though, is a very subtle difference. The Montauk 170 has a modified V-hull which helps the 90-horsepower Mercury-outboard driven motorboat move along at well over 40 mph when the throttle is opened wide.The 170 has an almost seven-foot beam, making her a stable platform for seven passengers.Slightly heavier than the 150, the Montauk still only draws an amazing nine inches of water.For buyers who cannot afford the 90-horsepower engine, the 170 will also move along quite nicely with a 60-horsepower outboard.Whaler Montauk 190The 19-foot Whaler Montauk 190 is 19-feet long and sits on an eight-foot beam. Because of the construction of the Whaler with wide, shallow bottom, she only draws 12 inches of water.Imagine a 19-footer, mounting a 115-horsepower Vorado, or 90-horsepower Mercury outboard engine with a 12-inch draft. Its quite a feat. However, when you consider the heritage of the Whaler you have an idea of just what is involved in getting that shallow draft. The 190 is the roomiest of the Montauk line and features a built-in fuel tank. This is the type of model where you might run into some rough seas as there is a rather full folding cloth weather top that provides pretty good coverage around the console so they have included four grab rails around the gunwales so your seven passengers can hold on.Whaler Montauk 210 (new)An addition to the Montauk Line is the 210. She is far more weatherly than other Whaler models as she does have the center console and the standard acrylic windshield but she has a full T-frame roof and frame to form what you can consider a small cabin, although it is center-mounted.The Montauk 210 also includes an enclosed head in the bow and if you look closely at the framerails for the T-top youll see holders for up to six fishing rods. The is actually made for some real fishing as she has three bench seats the center reversible seat, rear bench with a very discrete transom for skiing if you want to do that and a three-place bench in front of the windshield/cabin area.An interesting addition is the space Whaler has left for electronics (including the wiring loom or holes for the loom.At 21-feet shes the longest Montauk model and her 8.6-foot beam make her a stable platform. Her draw is only 13 inches. Her standard powerplant is a 200-horsepower outboard, although she can also mount a 150 and perform well.
