The Grand Soleil GS 40 2022 vs Grand Soleil GS 45 2010 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 Grand Soleil GS 45 2010 measures 45,7 feet overall (2010), giving it roughly 3,4 additional feet of deck space compared to the Grand Soleil GS 40 2022 at 42,3 feet (2022). Weight tells a clearer story for trailering families: the Grand Soleil GS 45 2010 tips the scales at 21 164 lbs — 4 630 lbs less than the Grand Soleil GS 40 2022 at 16 534 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 — 40 hp for the Grand Soleil GS 40 2022 and 55 hp for the Grand Soleil GS 45 2010. 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. Fuel capacity breaks the other way: the Grand Soleil GS 45 2010 carries 61 gallons versus 48 gallons in the Grand Soleil GS 40 2022. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Grand Soleil GS 45 2010 is rated for 13 passengers, while the Grand Soleil GS 40 2022 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Grand Soleil GS 45 2010 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Grand Soleil GS 45 2010 displaces 21 164 lbs — a 4 630-lb difference over the Grand Soleil GS 40 2022 at 16 534 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.
Both boats draw a similar depth — 7,9 ft and 7,6 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Grand Soleil GS 40 2022 uses fractional_rig_sloop rigging. For auxiliary power the Grand Soleil GS 45 2010 carries a 55-hp engine against 40 hp on the Grand Soleil GS 40 2022. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Hull speed is rated at 8,4 knots for the Grand Soleil GS 45 2010 and 7,9 knots for the Grand Soleil GS 40 2022.
Bottom line: The Grand Soleil GS 45 2010 is the offshore and bluewater choice — at 21 164 lbs displacement and 46 ft it has the load capacity, range, and seakeeping for extended passages. The Grand Soleil GS 40 2022 at 16 534 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
