Boston Whaler 170 Dauntless 2017 vs Boston Whaler 270 Dauntless 2022 — Same Brand, Different Boat

The Boston Whaler 170 Dauntless 2017 vs Boston Whaler 270 Dauntless 2022 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 225 hp, the Boston Whaler 270 Dauntless 2022 has a 110-hp advantage over the Boston Whaler 170 Dauntless 2017's 115-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 270 Dauntless 2022 carries 152 gallons versus 35 gallons in the Boston Whaler 170 Dauntless 2017. 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 270 Dauntless 2022 is rated for 8 passengers, while the Boston Whaler 170 Dauntless 2017 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 270 Dauntless 2022 could be the deciding factor.

Bottom line: Choose the Boston Whaler 270 Dauntless 2022 if your priority is putting more people on the water — it handles 8 passengers and at 27,1 ft it has the deck room to back that rating up comfortably. The Boston Whaler 170 Dauntless 2017 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
