When two boats share the same hull type — in this case both the Achilles 126SB 2010 and the Achilles SU-16 2011 are inflatable non rigid designs with inflatable 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 Achilles SU-16 2011 measures 16,0 feet overall (2011), giving it roughly 3,5 additional feet of deck space compared to the Achilles 126SB 2010 at 12,5 feet (2010). Weight tells a clearer story for trailering families: the Achilles SU-16 2011 tips the scales at 378 lbs — 365 lbs less than the Achilles 126SB 2010 at 13 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 Achilles SU-16 2011 tops out at 75 hp. Engine specs for the Achilles 126SB 2010 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The Achilles SU-16 2011 is rated for 9 passengers, while the Achilles 126SB 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles SU-16 2011 could be the deciding factor.
The Achilles SU-16 2011 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles 126SB 2010 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Achilles SU-16 2011 if your priority is putting more people on the water — it handles 9 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Achilles 126SB 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
