When two boats share the same hull type — in this case both the Boston Whaler 170 Super Sport 2012 and the Boston Whaler 190 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?

On paper these two are close siblings in the size department — Boston Whaler 170 Super Sport 2012 at 17,0 ft versus Boston Whaler 190 Montauk 2008 at 19,0 ft. At 115 lbs and 19 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 135 hp, the Boston Whaler 190 Montauk 2008 has a 45-hp advantage over the Boston Whaler 170 Super Sport 2012's 90-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 Super Sport 2012 carries 13 gallons versus 6 gallons in the Boston Whaler 190 Montauk 2008. 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 190 Montauk 2008 is rated for 8 passengers, while the Boston Whaler 170 Super Sport 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 190 Montauk 2008 could be the deciding factor.
