The Boston Whaler 110 Sport 2006 vs Boston Whaler 170 Dauntless 2017 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 115 hp, the Boston Whaler 170 Dauntless 2017 has a 90-hp advantage over the Boston Whaler 110 Sport 2006'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 Dauntless 2017 carries 35 gallons versus 3 gallons in the Boston Whaler 110 Sport 2006. 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 Dauntless 2017 is rated for 5 passengers, while the Boston Whaler 110 Sport 2006 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 Dauntless 2017 could be the deciding factor.
