The Grand Soleil GS 45 2010 vs Grand Soleil GS 52 2023 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 52 2023 measures 55,1 feet overall (2023), giving it roughly 9,4 additional feet of deck space compared to the Grand Soleil GS 45 2010 at 45,7 feet (2010). Weight tells a clearer story for trailering families: the Grand Soleil GS 52 2023 tips the scales at 36 376 lbs — 15 212 lbs less than the Grand Soleil GS 45 2010 at 21 164 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 80 hp, the Grand Soleil GS 52 2023 has a 25-hp advantage over the Grand Soleil GS 45 2010's 55-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 Grand Soleil GS 52 2023 is rated for 16 passengers, while the Grand Soleil GS 45 2010 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Grand Soleil GS 52 2023 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Grand Soleil GS 52 2023 displaces 36 376 lbs — a 15 212-lb difference over the Grand Soleil GS 45 2010 at 21 164 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 Grand Soleil GS 52 2023 draws 9,6 ft, compared to 7,6 ft for the Grand Soleil GS 45 2010. That 2,0-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 Grand Soleil GS 45 2010 is rigged as a fractional_rig_sloop while the Grand Soleil GS 52 2023 carries Sloop rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. For auxiliary power the Grand Soleil GS 52 2023 carries a 80-hp engine against 55 hp on the Grand Soleil GS 45 2010. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Bottom line: The Grand Soleil GS 52 2023 is the offshore and bluewater choice — at 36 376 lbs displacement and 55 ft it has the load capacity, range, and seakeeping for extended passages. The Grand Soleil GS 45 2010 at 21 164 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
