Design and Construction
Both hull and deck are fibreglass, with the deck built as a sandwich to improve the indoor climate as the original review recorded — a detail that speaks to the boat's Nordic roots, where condensation control matters as much as structural simplicity. The keel is iron, and the ballast ratio sits at 43 percent, while a displacement-to-length ratio of 263 and a length-to-beam ratio of 3.15 describe a hull that is neither particularly slender nor voluminous by modern standards, but carries its 15,432 pounds with a 6,614-pound iron keel low in the bilge. The wetted surface measures about 387 square feet, and the immersion rate of roughly 1,179 pounds per inch tells you how stubbornly she holds her waterline under load. These are the numbers of a boat tuned for steadiness rather than sparkling acceleration.
Rig and Handling
The 360 is a masthead sloop, and her sail-area-to-displacement ratio is 13.8 on the ISO reference sail, rising to 16.2 with a 135 percent genoa — enough to keep her moving in a breeze without demanding a masthead kite for everyday sailing. Running rig is generous: halyards run about 103 feet at half-inch diameter, sheets for jib and genoa are 35 feet and change at 0.55 inch, and the mainsheet is 88 feet long, all sized for a boat that expects to be handled by a small crew with adequate mechanical advantage. Under power, the Volvo Penta 2003 TD Turbo diesel pushes her to a measured 8.0 knots, while a calculated maximum of about 6.4 knots applies to the non-turbo 2003 T; the theoretical hull-speed limit for her length is 7.4 knots, and the shaft drive transmits through a conventional arrangement. The capsize screening value is 1.72 and the Motion Comfort Ratio spans 30 to 34, figures that place her in the reassuring band for a cruiser of this size.
Accommodations
Below, the interior is mahogany, in keeping with the Scandinavian cruiser convention of the period. The cabin joinery follows the same material language found across many contemporary Swedish builds, lending a warm, enclosed feel that the sandwich deck helps keep temperate. The boat's 11.2-foot beam provides a layout typical of a liveaboard-minded 35-footer.
Refits and Ownership
The original engine options center on the Volvo Penta 2003 series, a shaft-drive diesel of 43 horsepower in the spec record. The running rig dimensions given above are a useful baseline for any owner replacing halyards or sheets, and the 135 percent genoa's effect on sail-area ratio is worth noting for those considering a re-cut or a new working jib. The iron keel and solid fibreglass hull mean there is no cored bottom to survey for water ingress, though the sandwich deck remains the one composite structure aboard.
The Verdict
The Najad 360 is a straightforward, well-mannered cruiser from Karlsson's mid-80s pencil and Najad's Swedish yard — a boat built to be lived with in northern waters, not to win a buoy race. Her heavy displacement and high ballast ratio give her poise in a seaway, and the rig dimensions make her easy to re-rig from known quantities.
Pros
- Iron fin keel with 43 percent ballast ratio and steady Motion Comfort Ratio of 30–34
- Sandwich deck improving cabin climate; solid fibreglass hull below
- Well-documented running-rig sizes for straightforward replacement
Cons
- Modest sail-area-to-displacement (13.8) suggests limited light-air sparkle without a genoa
- Sandwich deck is the lone composite structure, a potential survey focus
