When two boats share the same hull type — in this case both the Klamath 19 ft. Baja 2011 and the Klamath 21 ft. Baja 2012 are deep 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 ft. Baja 2011 at 19,3 ft versus Klamath 21 ft. Baja 2012 at 21,3 ft. At 75 lbs and 115 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 150 hp, the Klamath 21 ft. Baja 2012 has a 60-hp advantage over the Klamath 19 ft. Baja 2011's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 2 gal and 5 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Klamath 21 ft. Baja 2012 is rated for 8 passengers, while the Klamath 19 ft. Baja 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Klamath 21 ft. Baja 2012 could be the deciding factor.
Bottom line: Choose the Klamath 21 ft. Baja 2012 if your priority is putting more people on the water — it handles 8 passengers and at 21,3 ft it has the deck room to back that rating up comfortably. The Klamath 19 ft. Baja 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
