Achilles HB-350DX 2011 vs Achilles LSR-310 2010 — Same Brand, Different Boat

Matching a inflatable rigid Achilles HB-350DX 2011 against a inflatable non rigid Achilles LSR-310 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Achilles HB-350DX 2011 at 11,5 ft versus Achilles LSR-310 2010 at 10,2 ft. At 2 lbs and 101 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.

Both boats share a closely matched power ceiling — 30 hp for the Achilles HB-350DX 2011 and 10 hp for the Achilles LSR-310 2010. 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 LSR-310 2010 caps at 4. 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 10 lbs per hp for the Achilles LSR-310 2010. 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 LSR-310 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 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 LSR-310 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Achilles HB-350DX 2011 vs Achilles LSR-310 2010 — Common Questions

Which is the larger boat — the Achilles HB-350DX 2011 or the Achilles LSR-310 2010?
The Achilles HB-350DX 2011 is the longer of the two at 11,5 feet overall. The Achilles LSR-310 2010 comes in at 10,2 feet, making it roughly 1,3 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 LSR-310 2010?
For trailering, the Achilles HB-350DX 2011 has the edge at 2 lbs dry weight versus 101 lbs for the Achilles LSR-310 2010. 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.
Which boat can handle a bigger outboard?
The Achilles HB-350DX 2011 is rated to a maximum of 30 hp, giving it the larger power ceiling. The Achilles LSR-310 2010 tops out at 10 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Achilles HB-350DX 2011 is Coast Guard rated for 6 passengers, while the Achilles LSR-310 2010 is certified for 4. 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 10 lbs per hp for the Achilles LSR-310 2010. 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 62" for the Achilles LSR-310 2010. 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 LSR-310 2010 from the same manufacturer?
Yes — both the Achilles HB-350DX 2011 and the Achilles LSR-310 2010 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.
