Archambault A31 2009 vs Archambault Grand Surprise 1999 — Same Brand, Different Boat

The Archambault A31 2009 vs Archambault Grand Surprise 1999 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 — Archambault A31 2009 at 31,4 ft versus Archambault Grand Surprise 1999 at 31,4 ft. Weight tells a clearer story for trailering families: the Archambault A31 2009 tips the scales at 6 945 lbs — 1 103 lbs more than the Archambault Grand Surprise 1999 at 5 842 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.

Both boats share a closely matched power ceiling — 14 hp for the Archambault A31 2009 and 19 hp for the Archambault Grand Surprise 1999. 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 9 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.

Both boats sit in a similar displacement bracket — 6 945 lbs for the Archambault A31 2009 and 5 842 lbs for the Archambault Grand Surprise 1999. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.

Both boats draw a similar depth — 6,2 ft and 6,8 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Archambault A31 2009 uses Sloop rigging.

Bottom line: The Archambault A31 2009 and Archambault Grand Surprise 1999 are closely matched on paper. A sea trial on both in representative conditions is the only reliable way to find which one suits your sailing style, home port, and intended cruising ground.

Archambault A31 2009 vs Archambault Grand Surprise 1999 — Common Questions

Which is the larger boat — the Archambault A31 2009 or the Archambault Grand Surprise 1999?
The Archambault Grand Surprise 1999 is the longer of the two at 31,4 feet overall. The Archambault A31 2009 comes in at 31,4 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 Archambault A31 2009 or the Archambault Grand Surprise 1999?
For trailering, the Archambault Grand Surprise 1999 has the edge at 5 842 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.
How many people can each boat hold?
The Archambault A31 2009 is Coast Guard rated for 9 passengers, while the Archambault Grand Surprise 1999 is certified for 9. 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 Grand Surprise 1999?
The Archambault Grand Surprise 1999 has the deeper draft at 6,8 ft, versus 6,2 ft for the Archambault A31 2009. 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 Grand Surprise 1999 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 Grand Surprise 1999 at 5 842 lbs will typically be livelier and more responsive in lighter conditions.
Which boat is wider, and does it affect trailering?
The Archambault A31 2009 measures 128" wide, compared to 109" for the Archambault Grand Surprise 1999. 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 Grand Surprise 1999 from the same manufacturer?
Yes — both the Archambault A31 2009 and the Archambault Grand Surprise 1999 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.
