When two boats share the same hull type — in this case both the Boston Whaler 110 Sport 2010 and the Boston Whaler 170 Montauk 2008 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Boston Whaler 170 Montauk 2008 measures 17,0 feet overall (2008), giving it roughly 5,7 additional feet of deck space compared to the Boston Whaler 110 Sport 2010 at 11,3 feet (2010). At 46 lbs and 14 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 90 hp, the Boston Whaler 170 Montauk 2008 has a 65-hp advantage over the Boston Whaler 110 Sport 2010's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Boston Whaler 170 Montauk 2008 carries 13 gallons versus 3 gallons in the Boston Whaler 110 Sport 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Boston Whaler 170 Montauk 2008 is rated for 7 passengers, while the Boston Whaler 110 Sport 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 170 Montauk 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Boston Whaler 170 Montauk 2008 comes in at 0 lbs per hp versus 2 lbs per hp for the Boston Whaler 110 Sport 2010. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Boston Whaler 170 Montauk 2008 if your priority is putting more people on the water — it handles 7 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Boston Whaler 110 Sport 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
