Achilles HB-350DX 2011 vs Achilles SG-124 2006 — Same Brand, Different Boat

The Achilles HB-350DX 2011 vs Achilles SG-124 2006 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.

On paper these two are close siblings in the size department — Achilles HB-350DX 2011 at 11,5 ft versus Achilles SG-124 2006 at 12,0 ft. Weight tells a clearer story for trailering families: the Achilles SG-124 2006 tips the scales at 175 lbs — 173 lbs less than the Achilles HB-350DX 2011 at 2 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.

Both boats share a closely matched power ceiling — 30 hp for the Achilles HB-350DX 2011 and 35 hp for the Achilles SG-124 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

For family outings this is probably the sharpest distinction between the two. The Achilles HB-350DX 2011 is rated for 6 passengers, while the Achilles SG-124 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles HB-350DX 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Achilles HB-350DX 2011 comes in at 0 lbs per hp versus 5 lbs per hp for the Achilles SG-124 2006. 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 HB-350DX 2011 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Achilles SG-124 2006 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 HB-350DX 2011 if your priority is putting more people on the water — it handles 6 passengers and at 11,5 ft it has the deck room to back that rating up comfortably. The Achilles SG-124 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Achilles HB-350DX 2011 vs Achilles SG-124 2006 — Common Questions

Which is the larger boat — the Achilles HB-350DX 2011 or the Achilles SG-124 2006?
The Achilles SG-124 2006 is the longer of the two at 12,0 feet overall. The Achilles HB-350DX 2011 comes in at 11,5 feet, making it roughly 0,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles HB-350DX 2011 or the Achilles SG-124 2006?
For trailering, the Achilles HB-350DX 2011 has the edge at 2 lbs dry weight versus 175 lbs for the Achilles SG-124 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Achilles HB-350DX 2011 is Coast Guard rated for 6 passengers, while the Achilles SG-124 2006 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The Achilles HB-350DX 2011 has a better power-to-weight ratio at 0 lbs per hp compared to 5 lbs per hp for the Achilles SG-124 2006. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Achilles HB-350DX 2011 measures 69" wide, compared to 64" for the Achilles SG-124 2006. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Achilles HB-350DX 2011 and Achilles SG-124 2006 from the same manufacturer?
Yes — both the Achilles HB-350DX 2011 and the Achilles SG-124 2006 are built by Achilles. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
