When two boats share the same hull type — in this case both the Klamath 12 ft. Deluxe 2007 and the Klamath 15 ADW 2012 are modified vee designs with composite construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Klamath 15 ADW 2012 measures 15,2 feet overall (2012), giving it roughly 3,2 additional feet of deck space compared to the Klamath 12 ft. Deluxe 2007 at 12,0 feet (2007). Weight tells a clearer story for trailering families: the Klamath 15 ADW 2012 tips the scales at 435 lbs — 420 lbs less than the Klamath 12 ft. Deluxe 2007 at 15 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 2012 has a 30-hp advantage over the Klamath 12 ft. Deluxe 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 ADW 2012 is rated for 6 passengers, while the Klamath 12 ft. Deluxe 2007 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Klamath 15 ADW 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Klamath 12 ft. Deluxe 2007 comes in at 1 lbs per hp versus 10 lbs per hp for the Klamath 15 ADW 2012. 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 2012 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 12 ft. Deluxe 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
