When two boats share the same hull type — in this case both the Achilles 126SB 2009 and the Achilles SPD-335 2012 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?
On paper these two are close siblings in the size department — Achilles 126SB 2009 at 12,5 ft versus Achilles SPD-335 2012 at 11,0 ft. Weight tells a clearer story for trailering families: the Achilles SPD-335 2012 tips the scales at 123 lbs — 110 lbs less than the Achilles 126SB 2009 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 SPD-335 2012 tops out at 20 hp. Engine specs for the Achilles 126SB 2009 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 126SB 2009 is rated for 7 passengers, while the Achilles SPD-335 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles 126SB 2009 could be the deciding factor.
The Achilles SPD-335 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles 126SB 2009 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 126SB 2009 if your priority is putting more people on the water — it handles 7 passengers and at 12,5 ft it has the deck room to back that rating up comfortably. The Achilles SPD-335 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
