The Grand Soleil GS 37 - B&C Deep draft 2005 vs Grand Soleil GS 42 LC 2020 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 42 LC 2020 measures 45,4 feet overall (2020), giving it roughly 6,9 additional feet of deck space compared to the Grand Soleil GS 37 - B&C Deep draft 2005 at 38,5 feet (2005). Weight tells a clearer story for trailering families: the Grand Soleil GS 42 LC 2020 tips the scales at 22 200 lbs — 7 209 lbs less than the Grand Soleil GS 37 - B&C Deep draft 2005 at 14 991 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 50 hp, the Grand Soleil GS 42 LC 2020 has a 23-hp advantage over the Grand Soleil GS 37 - B&C Deep draft 2005's 27-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Grand Soleil GS 42 LC 2020 carries 53 gallons versus 37 gallons in the Grand Soleil GS 37 - B&C Deep draft 2005. 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 42 LC 2020 is rated for 13 passengers, while the Grand Soleil GS 37 - B&C Deep draft 2005 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Grand Soleil GS 42 LC 2020 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Grand Soleil GS 42 LC 2020 displaces 22 200 lbs — a 7 209-lb difference over the Grand Soleil GS 37 - B&C Deep draft 2005 at 14 991 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 — 7,1 ft and 7,4 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Grand Soleil GS 37 - B&C Deep draft 2005 uses Sloop rigging. Helm style differs too: the Grand Soleil GS 37 - B&C Deep draft 2005 uses a 1 wheel versus a 2 wheels on the Grand Soleil GS 42 LC 2020. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Grand Soleil GS 42 LC 2020 carries a 50-hp engine against 27 hp on the Grand Soleil GS 37 - B&C Deep draft 2005. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
For extended cruising, water capacity matters: the Grand Soleil GS 37 - B&C Deep draft 2005 carries 95 gallons versus 79 gallons on the Grand Soleil GS 42 LC 2020 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Grand Soleil GS 42 LC 2020 is the offshore and bluewater choice — at 22 200 lbs displacement and 45 ft it has the load capacity, range, and seakeeping for extended passages. The Grand Soleil GS 37 - B&C Deep draft 2005 at 14 991 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
