Hull, Structure, and Design Philosophy
The GS 40's hull reflects the same thinking that defines Botin Carkeek's racing programme. It features a longer waterline, reduced wetted area, and a deep, efficient rudder and keel whose geometry was developed in collaboration with Ferrari's aerodynamics department. That pedigree shows up in how the boat moves through the water rather than just in marketing language. Above the waterline, the laminate is unidirectional fiberglass and vinylester resin with a cross-linked PVC foam core called Termanto in both the topsides and deck.
The internal structure is built around an epoxy-coated galvanized-steel grid bonded inside the hull that handles loads from the chainplates, keel stub, and mast step. The yard's choice of mild steel raised eyebrows among the Cruising World judging panel, who noted concern about long-term corrosion. Grand Soleil's response — that the grid is fully accessible via screw-held sole panels for inspection — is a reasonable one, but prospective owners should confirm that access panels remain functional and that the grid is inspected as part of routine maintenance.
The visual result is a boat with a tapered cabin house, uncluttered decks, and an elegant Italian interior aesthetic that feels coherent from keel to masthead. The lines are clean without being austere.
Deck Layout and Sail Handling
Grand Soleil ran halyards and reef lines aft under the coachroof, keeping the foredeck clear and reducing the need for crew to leave the cockpit. The adjustable genoa tracks are tucked against the cabin side, an arrangement that minimises obstructions on the side decks — though it does mean the outward-opening cabin ports can get in the way when moving forward.
The long, low boom maximises sail area and produces impressive power, but it rewards situational awareness: head clearance in a gybe is limited, and the Harken traveller positioned just forward of the wheel means a slack mainsheet can foul the binnacle when tacking across a reach. The standard single set of cockpit winches routes the mainsheet to the coachroof, out of reach of the helm; most owners add a second pair so the double-ended sheet can run to primaries at either end of the traveller. The 12-inch bridgedeck, required under EU certification rules, provides meaningful protection against cockpit-to-cabin flooding. One detail worth addressing before going offshore: the companionway boards, despite their clever self-stowing system, leave a finger-width gap at the bottom when closed.
Sailing Performance
On a test day with gusts in the low thirties, the evaluation team found they didn't need the second reef they expected to tuck in. With a partially furled genoa and one reef in the main, the boat remained solid and responsive — the kind of reassurance that builds trust quickly. Upwind, the numbers speak: tacking through 110 degrees at over 8 knots in heavy air with imperfect trim is a meaningful result. On a reach in 25 knots, GPS showed 7.4 knots over ground.
Under power, the 40-horsepower Volvo Penta saildrive with a two-bladed folding prop pushed the boat to 6.6 knots at 2,500 rpm and 7.6 knots at 2,900 rpm. The folding prop is the right choice on a boat this quick — avoiding the parasitic drag of a fixed blade matters when you're this close to raceboat geometry.
Interior and Accommodations
The three-cabin layout belies any assumption that the GS 40's performance priorities came at the interior's expense. The forward master cabin carries a queen-size centerline berth with optional en-suite head, and the reading lights are well-placed and functional — a detail that rewards actual use. In the main saloon, a C-shaped dinette with a stand-alone bench on centreline provides both dining space and a back-brace for the cook in the in-line port-side galley.
Navigation gets proper treatment. The nav station has room for full-size charts, a laptop, and additional electronics, with a drip rail under the ports protecting the electrical panel — a detail that speaks to real-world seamanship thinking rather than show-boat presentation. The twin quarter cabins offer standing headroom, hanging lockers, double berths, and split mattresses that accept lee cloths, making them workable sea berths rather than purely dockside bunks.
A few galley niggles: the upper lockers lack content restraint systems for passage-making, the stove needs the factory rubber stop removed before it can swing properly, and the deep stainless double sink has a seacock that needs closing on starboard tack when well heeled.
Known Issues and Considerations
The structural steel grid is the one area requiring diligence. While the yard maintained that rust and corrosion do not become problems over time, the choice of mild steel in an epoxy-coated but ultimately enclosed bilge environment deserves independent verification during pre-purchase survey. The access design is thoughtful; the metallurgy is a compromise worth understanding.
The absence of cabin-top handrails forward of the mast is a genuine safety gap — it is a common omission on this generation of European performance cruisers, but no less problematic for being common. Going forward in a blow requires careful movement and ideally jacklines rigged early. A stove guardrail is something cruising cooks should add rather than assume is fitted.
The Verdict
The Grand Soleil 40 is a boat that earns the word "exceptional" without the usual caveats. Its Ferrari-derived underwater sections, Cantiere del Pardo construction quality, and Botin Carkeek race experience combine to produce a performance cruiser that is genuinely fast, genuinely solid, and — perhaps most surprisingly — genuinely comfortable below. The weak points are all addressable: add handrail extensions forward, fit a second pair of cockpit winches, install a stove guardrail, seal the companionway gap, and survey the steel grid carefully. None of these are structural indictments. For club racing, coastal passages, or bluewater passages with an experienced hand on the wheel, this boat earns its place among the best dual-purpose designs of its era.
Pros
- Ferrari-developed hull lines produce measurable upwind and reaching performance
- Solid, confidence-inspiring construction with a D/L of 182 and ballast ratio of 0.33
- Exceptional nav station with full-size chart space and proper electronics ergonomics
- Three-cabin layout with a genuine queen centerline V-berth and usable quarter cabin sea berths
- Halyards and reef lines led aft, keeping foredeck work to a minimum
- Volvo Penta saildrive installation is clean and well-integrated
Cons
- Mild-steel internal grid requires diligent inspection; verify condition on any used example
- Cabin-top handrails do not extend forward of the mast — a safety gap in heavy air
- Single cockpit winch set is the base fit; second pair effectively required for normal sailing
- Companionway board gap needs sealing before offshore use
- Low boom demands consistent crew awareness; traveller placement can foul binnacle
- Upper saloon lockers need owner-fitted content restraints for passage-making
