Archambault A31 2009 vs Archambault by BG Race M 7.50 2015 — Same Brand, Different Boat

The Archambault A31 2009 vs Archambault by BG Race M 7.50 2015 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 Archambault A31 2009 measures 31,4 feet overall (2009), giving it roughly 6,7 additional feet of deck space compared to the Archambault by BG Race M 7.50 2015 at 24,7 feet (2015). Weight tells a clearer story for trailering families: the Archambault A31 2009 tips the scales at 6 945 lbs — 5 181 lbs more than the Archambault by BG Race M 7.50 2015 at 1 764 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 Archambault A31 2009 carries a rated maximum of 14 hp. Engine data for the Archambault by BG Race M 7.50 2015 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

For family outings this is probably the sharpest distinction between the two. The Archambault A31 2009 is rated for 9 passengers, while the Archambault by BG Race M 7.50 2015 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Archambault A31 2009 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Archambault A31 2009 displaces 6 945 lbs — a 5 181-lb difference over the Archambault by BG Race M 7.50 2015 at 1 764 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Archambault A31 2009 draws 6,2 ft, compared to 4,0 ft for the Archambault by BG Race M 7.50 2015. That 2,2-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.

The Archambault A31 2009 uses Sloop rigging. The Archambault A31 2009 has a documented auxiliary engine of 14 hp.

The Archambault by BG Race M 7.50 2015 is trailerable — a genuine advantage for sailors who prefer to keep their boat at home or explore multiple sailing venues.

Bottom line: The Archambault A31 2009 is the offshore and bluewater choice — at 6 945 lbs displacement and 31 ft it has the load capacity, range, and seakeeping for extended passages. The Archambault by BG Race M 7.50 2015 at 1 764 lbs is the more nimble, accessible option and is trailerable — easier to single-hand and better suited to coastal and inland sailing.

Archambault A31 2009 vs Archambault by BG Race M 7.50 2015 — Common Questions

Which is the larger boat — the Archambault A31 2009 or the Archambault by BG Race M 7.50 2015?
The Archambault A31 2009 is the longer of the two at 31,4 feet overall. The Archambault by BG Race M 7.50 2015 comes in at 24,7 feet, making it roughly 6,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Archambault A31 2009 or the Archambault by BG Race M 7.50 2015?
For trailering, the Archambault by BG Race M 7.50 2015 has the edge at 1 764 lbs dry weight versus 6 945 lbs for the Archambault A31 2009. 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.
What is the maximum horsepower rating for these boats?
The Archambault A31 2009 has a documented max rating of 14 hp. Engine specifications for the Archambault by BG Race M 7.50 2015 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Archambault A31 2009 is Coast Guard rated for 9 passengers, while the Archambault by BG Race M 7.50 2015 is certified for 7. 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 deeper draft — the Archambault A31 2009 or the Archambault by BG Race M 7.50 2015?
The Archambault A31 2009 has the deeper draft at 6,2 ft, versus 4,0 ft for the Archambault by BG Race M 7.50 2015. A deeper draft generally means better upwind performance and stability, but limits access to shallow anchorages and some marina berths. Always check the controlling depth of your home port and favourite cruising grounds before committing.
Is the Archambault A31 2009 or the Archambault by BG Race M 7.50 2015 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Archambault A31 2009 at 6 945 lbs displacement is the heavier, more load-carrying design — generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Archambault by BG Race M 7.50 2015 at 1 764 lbs will typically be livelier and more responsive in lighter conditions.
Can the Archambault by BG Race M 7.50 2015 be trailered?
The Archambault by BG Race M 7.50 2015 is listed as trailerable, giving owners the flexibility to launch from any suitable ramp and avoid permanent berthing costs. The Archambault A31 2009 is not listed as trailerable — it will need a marina berth or mooring.
Which boat is wider, and does it affect trailering?
The Archambault A31 2009 measures 128" wide, compared to 73" for the Archambault by BG Race M 7.50 2015. 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 Archambault A31 2009 and Archambault by BG Race M 7.50 2015 from the same manufacturer?
Yes — both the Archambault A31 2009 and the Archambault by BG Race M 7.50 2015 are built by Archambault. 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.
