Boston Whaler 170 Dauntless 2017 vs Boston Whaler 220 Dauntless 2006 — Same Brand, Different Boat

The Boston Whaler 170 Dauntless 2017 vs Boston Whaler 220 Dauntless 2006 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 220 Dauntless 2006 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 170 Dauntless 2017 carries 35 gallons versus 9 gallons in the Boston Whaler 220 Dauntless 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 220 Dauntless 2006 is rated for 9 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 220 Dauntless 2006 could be the deciding factor.

Bottom line: Choose the Boston Whaler 220 Dauntless 2006 if your priority is putting more people on the water — it handles 9 passengers and at 22,0 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.

The Boston Whaler 220 Dauntless 2006 measures 102" wide, compared to 73" for the Boston Whaler 170 Dauntless 2017. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
