The Boston Whaler 170 Dauntless 2012 vs Boston Whaler 205 Conquest 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.

On paper these two are close siblings in the size department - Boston Whaler 170 Dauntless 2012 at 17,0 ft versus Boston Whaler 205 Conquest 2006 at 20,0 ft.

That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 200 hp, the Boston Whaler 205 Conquest 2006 has a 100-hp advantage over the Boston Whaler 170 Dauntless 2012's 100-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
