Achilles FRB-124 2010 vs Achilles HB-315DX 2006 — Same Brand, Different Boat

The Achilles FRB-124 2010 vs Achilles HB-315DX 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.

Size is the most obvious dividing line here. The Achilles FRB-124 2010 measures 12,3 feet overall (2010), giving it roughly 11,3 additional feet of deck space compared to the Achilles HB-315DX 2006 at 1,0 feet (2006). At 154 lbs and 159 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 FRB-124 2010 and 20 hp for the Achilles HB-315DX 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.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Achilles FRB-124 2010 comes in at 6 lbs per hp versus 8 lbs per hp for the Achilles HB-315DX 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.

Bottom line: The Achilles FRB-124 2010 at 12,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Achilles HB-315DX 2006 at 1,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Achilles FRB-124 2010 vs Achilles HB-315DX 2006 — Common Questions

Which is the larger boat — the Achilles FRB-124 2010 or the Achilles HB-315DX 2006?
The Achilles FRB-124 2010 is the longer of the two at 12,3 feet overall. The Achilles HB-315DX 2006 comes in at 1,0 feet, making it roughly 11,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles FRB-124 2010 or the Achilles HB-315DX 2006?
For trailering, the Achilles FRB-124 2010 has the edge at 154 lbs dry weight versus 159 lbs for the Achilles HB-315DX 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 FRB-124 2010 is Coast Guard rated for 5 passengers, while the Achilles HB-315DX 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 FRB-124 2010 has a better power-to-weight ratio at 6 lbs per hp compared to 8 lbs per hp for the Achilles HB-315DX 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-315DX 2006 measures 65" wide, compared to 3" for the Achilles FRB-124 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 FRB-124 2010 and Achilles HB-315DX 2006 from the same manufacturer?
Yes — both the Achilles FRB-124 2010 and the Achilles HB-315DX 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.
