Achilles HB-350DX 2007 vs Achilles SPD-335 2008 — Same Brand, Different Boat

The Achilles HB-350DX 2007 vs Achilles SPD-335 2008 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 2007 at 11,0 ft versus Achilles SPD-335 2008 at 11,0 ft. At 187 lbs and 123 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 — 25 hp for the Achilles HB-350DX 2007 and 20 hp for the Achilles SPD-335 2008. 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 2007 is rated for 6 passengers, while the Achilles SPD-335 2008 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 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Achilles SPD-335 2008 comes in at 6 lbs per hp versus 8 lbs per hp for the Achilles HB-350DX 2007. 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.

Bottom line: Choose the Achilles HB-350DX 2007 if your priority is putting more people on the water — it handles 6 passengers and at 11,0 ft it has the deck room to back that rating up comfortably. The Achilles SPD-335 2008 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 2007 vs Achilles SPD-335 2008 — Common Questions

Which is the larger boat — the Achilles HB-350DX 2007 or the Achilles SPD-335 2008?
The Achilles SPD-335 2008 is the longer of the two at 11,0 feet overall. The Achilles HB-350DX 2007 comes in at 11,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles HB-350DX 2007 or the Achilles SPD-335 2008?
For trailering, the Achilles SPD-335 2008 has the edge at 123 lbs dry weight versus 187 lbs for the Achilles HB-350DX 2007. 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 2007 is Coast Guard rated for 6 passengers, while the Achilles SPD-335 2008 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 SPD-335 2008 has a better power-to-weight ratio at 6 lbs per hp compared to 8 lbs per hp for the Achilles HB-350DX 2007. 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 2007 measures 69" wide, compared to 66" for the Achilles SPD-335 2008. 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 2007 and Achilles SPD-335 2008 from the same manufacturer?
Yes — both the Achilles HB-350DX 2007 and the Achilles SPD-335 2008 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.
