The Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004 vs Grand Soleil GS 50 2011 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 50 2011 measures 51,4 feet overall (2011), giving it roughly 5,7 additional feet of deck space compared to the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004 at 45,7 feet (2004). Weight tells a clearer story for trailering families: the Grand Soleil GS 50 2011 tips the scales at 29 762 lbs — 8 598 lbs less than the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004 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.
Both boats share a closely matched power ceiling — 55 hp for the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004 and 75 hp for the Grand Soleil GS 50 2011. 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 50 2011 carries 82 gallons versus 61 gallons in the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004. 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 50 2011 is rated for 15 passengers, while the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004 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 50 2011 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Grand Soleil GS 50 2011 displaces 29 762 lbs — a 8 598-lb difference over the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004 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 50 2011 draws 8,6 ft, compared to 6,5 ft for the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004. That 2,1-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 - J&V Shoal draft Shoal draft 2004 is rigged as a fractional_rig_sloop while the Grand Soleil GS 50 2011 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. Helm style differs too: the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004 uses a 1 wheel versus a 2 wheels on the Grand Soleil GS 50 2011. 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 50 2011 carries a 75-hp engine against 55 hp on the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004. 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 8,9 knots for the Grand Soleil GS 50 2011 and 8,4 knots for the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004. For extended cruising, water capacity matters: the Grand Soleil GS 50 2011 carries 137 gallons versus 106 gallons on the Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Grand Soleil GS 50 2011 is the offshore and bluewater choice — at 29 762 lbs displacement and 51 ft it has the load capacity, range, and seakeeping for extended passages. The Grand Soleil GS 45 - J&V Shoal draft Shoal draft 2004 at 21 164 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
