Grand Soleil GS 37 - B&C Deep draft 2005 vs Grand Soleil GS 43 2006 — Same Brand, Different Boat

The Grand Soleil GS 37 - B&C Deep draft 2005 vs Grand Soleil GS 43 2006 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 43 2006 measures 43,6 feet overall (2006), giving it roughly 5,1 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 43 2006 tips the scales at 19 621 lbs — 4 630 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 55 hp, the Grand Soleil GS 43 2006 has a 28-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 43 2006 carries 61 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 43 2006 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 43 2006 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Grand Soleil GS 43 2006 displaces 19 621 lbs — a 4 630-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 7,6 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. For auxiliary power the Grand Soleil GS 43 2006 carries a 55-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.

Hull speed is rated at 8,2 knots for the Grand Soleil GS 43 2006 and 7,6 knots for the Grand Soleil GS 37 - B&C Deep draft 2005. For extended cruising, water capacity matters: the Grand Soleil GS 43 2006 carries 106 gallons versus 95 gallons on the Grand Soleil GS 37 - B&C Deep draft 2005 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Grand Soleil GS 43 2006 is the offshore and bluewater choice — at 19 621 lbs displacement and 44 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.

Grand Soleil GS 37 - B&C Deep draft 2005 vs Grand Soleil GS 43 2006 — Common Questions

Which is the larger boat — the Grand Soleil GS 37 - B&C Deep draft 2005 or the Grand Soleil GS 43 2006?
The Grand Soleil GS 43 2006 is the longer of the two at 43,6 feet overall. The Grand Soleil GS 37 - B&C Deep draft 2005 comes in at 38,5 feet, making it roughly 5,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Grand Soleil GS 37 - B&C Deep draft 2005 or the Grand Soleil GS 43 2006?
For trailering, the Grand Soleil GS 37 - B&C Deep draft 2005 has the edge at 14 991 lbs dry weight versus 19 621 lbs for the Grand Soleil GS 43 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Grand Soleil GS 43 2006 is rated to a maximum of 55 hp, giving it the larger power ceiling. The Grand Soleil GS 37 - B&C Deep draft 2005 tops out at 27 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Grand Soleil GS 37 - B&C Deep draft 2005 is Coast Guard rated for 11 passengers, while the Grand Soleil GS 43 2006 is certified for 13. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the deeper draft — the Grand Soleil GS 37 - B&C Deep draft 2005 or the Grand Soleil GS 43 2006?
The Grand Soleil GS 43 2006 has the deeper draft at 7,6 ft, versus 7,1 ft for the Grand Soleil GS 37 - B&C Deep draft 2005. A deeper draft generally means better upwind performance and stability, but limits access to shallow anchorages and some marina berths. Always check the controlling depth of your home port and favourite cruising grounds before committing.
Is the Grand Soleil GS 37 - B&C Deep draft 2005 or the Grand Soleil GS 43 2006 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Grand Soleil GS 43 2006 at 19 621 lbs displacement is the heavier, more load-carrying design — generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Grand Soleil GS 37 - B&C Deep draft 2005 at 14 991 lbs will typically be livelier and more responsive in lighter conditions.
Which is the faster sailboat — the Grand Soleil GS 37 - B&C Deep draft 2005 or the Grand Soleil GS 43 2006?
Based on rated hull speed, the Grand Soleil GS 43 2006 has an edge at 8,2 knots versus 7,6 knots for the Grand Soleil GS 37 - B&C Deep draft 2005. Keep in mind that actual sailing speed depends heavily on wind conditions, sail trim, bottom condition, and skipper experience — hull speed is a theoretical maximum, not a guarantee.
Which boat is better equipped for long-distance cruising?
For extended passages, fresh water capacity is a key indicator of cruising readiness. The Grand Soleil GS 43 2006 carries 106 gallons of fresh water compared to 95 gallons on the Grand Soleil GS 37 - B&C Deep draft 2005 — a meaningful advantage when watermaker installations or port stops aren't guaranteed.
Which boat is wider, and does it affect trailering?
The Grand Soleil GS 43 2006 measures 156" wide, compared to 144" for the Grand Soleil GS 37 - B&C Deep draft 2005. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Grand Soleil GS 37 - B&C Deep draft 2005 or the Grand Soleil GS 43 2006?
The Grand Soleil GS 43 2006 has the bigger tank at 61 gallons, versus 37 gallons on the Grand Soleil GS 37 - B&C Deep draft 2005. That 23-gallon difference translates to roughly 71–118 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Grand Soleil GS 37 - B&C Deep draft 2005 and Grand Soleil GS 43 2006 from the same manufacturer?
Yes — both the Grand Soleil GS 37 - B&C Deep draft 2005 and the Grand Soleil GS 43 2006 are built by Grand Soleil. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
