Matching a flat Klamath 13 ft. Wide Jac 2008 against a modified vee Klamath 15 ADW 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Klamath 13 ft. Wide Jac 2008 at 13,0 ft versus Klamath 15 ADW 2013 at 15,2 ft. Weight tells a clearer story for trailering families: the Klamath 15 ADW 2013 tips the scales at 435 lbs — 210 lbs less than the Klamath 13 ft. Wide Jac 2008 at 225 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 45 hp, the Klamath 15 ADW 2013 has a 25-hp advantage over the Klamath 13 ft. Wide Jac 2008's 20-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Klamath 15 ADW 2013 is rated for 6 passengers, while the Klamath 13 ft. Wide Jac 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Klamath 15 ADW 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Klamath 15 ADW 2013 comes in at 10 lbs per hp versus 11 lbs per hp for the Klamath 13 ft. Wide Jac 2008. 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.
Bottom line: Choose the Klamath 15 ADW 2013 if your priority is putting more people on the water — it handles 6 passengers and at 15,2 ft it has the deck room to back that rating up comfortably. The Klamath 13 ft. Wide Jac 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
