When two boats share the same hull type — in this case both the Klamath 19 GTCC 2012 and the Klamath Double Jac 2008 are modified vee designs with aluminum 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?
On paper these two are close siblings in the size department — Klamath 19 GTCC 2012 at 18,7 ft versus Klamath Double Jac 2008 at 16,0 ft. Weight tells a clearer story for trailering families: the Klamath Double Jac 2008 tips the scales at 495 lbs — 420 lbs less than the Klamath 19 GTCC 2012 at 75 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 115 hp, the Klamath 19 GTCC 2012 has a 75-hp advantage over the Klamath Double Jac 2008's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Klamath 19 GTCC 2012 at 18,7 ft is the right call if deck space, comfort, and entertaining are top of your list. The Klamath Double Jac 2008 at 16,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
