The Grand Soleil GS 42 LC 2020 vs Grand Soleil GS 58 2016 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 58 2016 measures 57,5 feet overall (2016), giving it roughly 12,1 additional feet of deck space compared to the Grand Soleil GS 42 LC 2020 at 45,4 feet (2020). Weight tells a clearer story for trailering families: the Grand Soleil GS 58 2016 tips the scales at 41 667 lbs — 19 467 lbs less than the Grand Soleil GS 42 LC 2020 at 22 200 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 150 hp, the Grand Soleil GS 58 2016 has a 100-hp advantage over the Grand Soleil GS 42 LC 2020's 50-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 58 2016 carries 211 gallons versus 53 gallons in the Grand Soleil GS 42 LC 2020. 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 58 2016 is rated for 17 passengers, while the Grand Soleil GS 42 LC 2020 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 58 2016 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Grand Soleil GS 58 2016 displaces 41 667 lbs — a 19 467-lb difference over the Grand Soleil GS 42 LC 2020 at 22 200 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 58 2016 draws 9,6 ft, compared to 7,4 ft for the Grand Soleil GS 42 LC 2020. 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 Grand Soleil GS 42 LC 2020 uses Sloop rigging. For auxiliary power the Grand Soleil GS 58 2016 carries a 150-hp engine against 50 hp on the Grand Soleil GS 42 LC 2020. 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 58 2016 carries 159 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 58 2016 is the offshore and bluewater choice — at 41 667 lbs displacement and 58 ft it has the load capacity, range, and seakeeping for extended passages. The Grand Soleil GS 42 LC 2020 at 22 200 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
