Achilles LSI-77 2006 vs Achilles SGX-132 2008 — Same Brand, Different Boat

The Achilles LSI-77 2006 vs Achilles SGX-132 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.

Size is the most obvious dividing line here. The Achilles SGX-132 2008 measures 13,0 feet overall (2008), giving it roughly 6,0 additional feet of deck space compared to the Achilles LSI-77 2006 at 7,0 feet (2006). Weight tells a clearer story for trailering families: the Achilles SGX-132 2008 tips the scales at 212 lbs — 206 lbs less than the Achilles LSI-77 2006 at 6 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 40 hp, the Achilles SGX-132 2008 has a 36-hp advantage over the Achilles LSI-77 2006's 4-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 SGX-132 2008 is rated for 6 passengers, while the Achilles LSI-77 2006 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Achilles SGX-132 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Achilles LSI-77 2006 comes in at 2 lbs per hp versus 5 lbs per hp for the Achilles SGX-132 2008. 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 SGX-132 2008 if your priority is putting more people on the water — it handles 6 passengers and at 13,0 ft it has the deck room to back that rating up comfortably. The Achilles LSI-77 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.

Achilles LSI-77 2006 vs Achilles SGX-132 2008 — Common Questions

Which is the larger boat — the Achilles LSI-77 2006 or the Achilles SGX-132 2008?
The Achilles SGX-132 2008 is the longer of the two at 13,0 feet overall. The Achilles LSI-77 2006 comes in at 7,0 feet, making it roughly 6,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Achilles LSI-77 2006 or the Achilles SGX-132 2008?
For trailering, the Achilles LSI-77 2006 has the edge at 6 lbs dry weight versus 212 lbs for the Achilles SGX-132 2008. 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 SGX-132 2008 is rated to a maximum of 40 hp, giving it the larger power ceiling. The Achilles LSI-77 2006 tops out at 4 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 LSI-77 2006 is Coast Guard rated for 2 passengers, while the Achilles SGX-132 2008 is certified for 6. 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 LSI-77 2006 has a better power-to-weight ratio at 2 lbs per hp compared to 5 lbs per hp for the Achilles SGX-132 2008. 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 SGX-132 2008 measures 69" wide, compared to 57" for the Achilles LSI-77 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 LSI-77 2006 and Achilles SGX-132 2008 from the same manufacturer?
Yes — both the Achilles LSI-77 2006 and the Achilles SGX-132 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.
