The Achilles Boats HB 240AL 2020 vs Achilles SU-18 2013 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Achilles SU-18 2013 measures 18,0 feet overall (2013), giving it roughly 10,9 additional feet of deck space compared to the Achilles Boats HB 240AL 2020 at 7,1 feet (2020). Weight tells a clearer story for trailering families: the Achilles SU-18 2013 tips the scales at 433 lbs — 345 lbs less than the Achilles Boats HB 240AL 2020 at 88 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 90 hp, the Achilles SU-18 2013 has a 84-hp advantage over the Achilles Boats HB 240AL 2020's 6-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 Achilles SU-18 2013 is rated for 11 passengers, while the Achilles Boats HB 240AL 2020 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles SU-18 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Achilles SU-18 2013 comes in at 5 lbs per hp versus 15 lbs per hp for the Achilles Boats HB 240AL 2020. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
The Achilles Boats HB 240AL 2020 is trailerable — a genuine lifestyle advantage at this size. The Achilles SU-18 2013 isn't listed as trailerable, which may mean a permanent berth or mooring is required.
The Achilles SU-18 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles Boats HB 240AL 2020 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-18 2013 if your priority is putting more people on the water — it handles 11 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Achilles Boats HB 240AL 2020 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
