Matching a flat Klamath 14 ft. Jac 2007 against a modified vee Klamath 15 Advantage 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 14 ft. Jac 2007 at 14,0 ft versus Klamath 15 Advantage 2013 at 15,2 ft. At 15 lbs and 25 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 45 hp, the Klamath 15 Advantage 2013 has a 30-hp advantage over the Klamath 14 ft. Jac 2007's 15-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 Advantage 2013 is rated for 6 passengers, while the Klamath 14 ft. Jac 2007 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 Advantage 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Klamath 15 Advantage 2013 comes in at 1 lbs per hp versus 1 lbs per hp for the Klamath 14 ft. Jac 2007. 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 Advantage 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 14 ft. Jac 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
