When two boats share the same hull type — in this case both the Klamath 14 Jac 2013 and the Klamath 19 GTX 2010 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?
Size is the most obvious dividing line here. The Klamath 19 GTX 2010 measures 18,7 feet overall (2010), giving it roughly 4,2 additional feet of deck space compared to the Klamath 14 Jac 2013 at 14,5 feet (2013). At 15 lbs and 75 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 115 hp, the Klamath 19 GTX 2010 has a 100-hp advantage over the Klamath 14 Jac 2013'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 19 GTX 2010 is rated for 7 passengers, while the Klamath 14 Jac 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Klamath 19 GTX 2010 could be the deciding factor.
Bottom line: Choose the Klamath 19 GTX 2010 if your priority is putting more people on the water — it handles 7 passengers and at 18,7 ft it has the deck room to back that rating up comfortably. The Klamath 14 Jac 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
