Design and Construction
Where the 4800 departed from precedent was in her accommodation-driven hull form and interior volume. Dufour built the hull and deck in solid fiberglass, and the boat’s 40.9 percent ballast-displacement ratio with a skeg-hung rudder reflects a stable, predictable cruising platform rather than a featherweight sprinter. She looked very much like a scaled-up 3800, yet was a substantially different creation compared with the company’s earlier models, trading some of the older boats’ character for a more modern, berth-dense interior. The 11-foot-4 beam gave Valentijn room to spread the cabin sideways without inflating the LOA, and the 27-foot-9 waterline kept her hull-speed ceiling near 7 knots.
Rig and Handling
The original sailplan paired a small mainsail with an enormous, deck-sweeping genoa — a low-effort, genoa-dominated rig that suited short-handed cruising but shaped her windward habits. Yachting Monthly found her performance under sail was reputed to be very good, yet she doesn’t point particularly high when close-hauled anchor, a trade-off of that modest main and vast foretriangle. The masthead sloop rig on a 45.9-foot mast above the waterline, with 503 square feet of sail area, produced a sail-area-displacement ratio of 15.25 — enough to keep her lively in a breeze without demanding a large crew.
Accommodations
The 4800 leaned hard into the French tradition for maximum crew berths, sleeping up to nine people without feeling like a pure charter cattle-car. She carried an early manifestation of an owner’s suite, placing a double berth — rather than the usual V-berths — and the heads forward of the main bulkhead, a layout cue that later became standard on cruising yachts. Aft, a double cabin came with its own washbasin, giving two couples real privacy. The galley was adequate for use in a seaway, a quiet but meaningful endorsement for a boat meant to be lived aboard offshore.
The Verdict
Yachting Monthly’s survey framed the 4800 as a turning point for Dufour: a bigger, more civilized 3800 that rewrote the builder’s interior playbook without abandoning seaworthy basics. She rewards the buyer who wants berth count and a genuine forward owner’s space in a 35-foot hull, and her solid-glass construction is straightforward to assess. The close-hauled limit is real, but the genoa-forward rig is easy to drive.
Pros
- Early owner’s-suite layout with forward double berth and heads
- Sleeps up to nine while keeping a private aft double with washbasin
- Solid fiberglass hull and deck, simple to survey
- Reputed very good sailing performance in normal cruising
Cons
- Does not point particularly high when close-hauled
- Small mainsail / huge genoa rig favors reaching over windward work
