Design and Construction
Dufour builds the 430's hull as a solid fiberglass full laminate in hand lay-up, while the deck is a foam-core GRP sandwich produced by vacuum injection, a method the builder uses to improve sound and thermal insulation. The Grand Large series is distinguished by the molded in bulwark and additional volume forward in the hull form, and on this hull a chine begins about station 3.8 and runs to the transom. There is a single rudder, and the test boat in YACHT's review carried a standard deep keel of 2.10 metres. One structural point deserves a buyer's attention: Dufour manufactures the hull without a collision bulkhead in the foredeck, a feature absent on all models up to 46 feet in the range.
Rig and Handling
The standard rig is a simple two-spar Z-Spars mast with external upper and lower shrouds, carrying a self-tacking jib and only the most necessary trim equipment. The main boom is attached very low on the mast and rises aft, and the mainsheet traveler sits on the cabintrunk top as installed ex shipyard. The jib can also be rigged to be self-tacking, with side deck jib tracks available for a wider sheeting base. Four winches flank the companionway for halyard, mainsheet, and vang controls, and the primary winches sit aft near the wheels. A permanently attached bowsprit serves as anchor housing. Writing in YACHT, test sailors found the boat with a 106 percent overlapping genoa made 6.4 knots in under 10 knots of wind at an 85-degree tacking angle, and with half that wind on genoa alone logged 7.8 knots, close to her 8.3-knot theoretical hull speed. The Grand Prix package adds a backstay tensioner, line-adjustable centreboards, and a double-sided mainsheet system for more performance.
Accommodations
Dufour offers two layouts: three cabins with two heads, or four cabins with two heads. The three-cabin arrangement places a galley forward, split port and starboard, with a short settee to port and a large L-shaped dinette with a centerline bench to starboard. The four-cabin version moves to a longitudinal starboard galley beside a U-shaped dinette, and drops the nav station for a tight cabin with upper and lower berths. In the foredeck the island berth sits far into the bow, narrowing to 1.25 metres at shoulder height, while the symmetrical aft cabins provide 1.68-metre sleeping widths with a 50-centimetre service channel between them. The deck shows all flush hatches, including large skylights just aft of the mast, and the semi-enclosed stern with side access to a 2.50-metre-wide bathing platform is standard.
Known Issues
Dufour leaves out a forward collision bulkhead on this hull, as on all models up to 46 feet, a choice noted in period testing. No recesses are provided in the hull for the solid, externally bolted chainplates, and rubbing strakes are not offered even as an option, leaving exposed fittings vulnerable at dockside.
The Verdict
The 430 Grand Large is a thoroughly modern volume cruiser: beamy, tall-sided, and laid out for charter-grade accommodation without pretending to blue-water fortification. Felci's hull delivers surprising light-air pace for her displacement, and the standard self-tacking setup keeps short-handed sailing manageable. The lack of a forward collision bulkhead is the one clear concession to interior space over offshore margin.
Pros
- High freeboard and wide stern create exceptional interior volume for the length
- Light-air performance close to hull speed with modest canvas
- Standard self-tacking jib and cabintrunk traveler simplify handling
- Four-cabin option sets a class benchmark for charter layouts
Cons
- No collision bulkhead in the foredeck
- Externally bolted chainplates without hull recesses and no rubbing strake option
- Forward island berth narrows to 1.25 metres at the shoulders
