The Triumph Boats 170 DC 2013 vs Triumph Boats 191 FS 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 — Triumph Boats 170 DC 2013 at 16,8 ft versus Triumph Boats 191 FS 2006 at 18,0 ft. Weight tells a clearer story for trailering families: the Triumph Boats 170 DC 2013 tips the scales at 1 287 lbs — 1 102 lbs more than the Triumph Boats 191 FS 2006 at 185 lbs. 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 175 hp, the Triumph Boats 191 FS 2006 has a 100-hp advantage over the Triumph Boats 170 DC 2013's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Triumph Boats 191 FS 2006 carries 45 gallons versus 14 gallons in the Triumph Boats 170 DC 2013. 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 Triumph Boats 191 FS 2006 is rated for 8 passengers, while the Triumph Boats 170 DC 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triumph Boats 191 FS 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Triumph Boats 191 FS 2006 comes in at 1 lbs per hp versus 17 lbs per hp for the Triumph Boats 170 DC 2013. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
