Design and Class Heritage
Groop's 1967 design was purpose-built as a one-design racer, and the class still races in high competition across twelve countries from Finland to the United States, organized through national associations in eight nations and a 1,700-owner international association. She is the second-largest World Sailing international keelboat class in the world, a standing that explains why a boat conceived almost sixty years ago still finds new buyers. The hull measures 8.31 meters overall with a 6.30-meter waterline, a 2.19-meter beam, and a 1.32-meter fin-keel draft; her 49.97 percent ballast ratio and a displacement that sources differ on (1,450 kg per class authority, 3,190 lb per Yachting Monthly) place her in the light-displacement racer camp. With a deep fin and short waterline she spins quickly in response to the helm in port anchor, a trait that makes her feel larger than her length in tight maneuvering.
Construction and Deck Layout
Artekno of Finland manufactured the H-Boat, and the class is built by two World Sailing-licensed builders to a high standard of finish. The solid fiberglass hull carries an iron ballast and a spade rudder, with a self-bailing cockpit that adds a measure of safety in rough water. On deck, a large foredeck and wide sidedecks make sail handling a pleasure anchor, while the cockpit is partitioned by a mainsheet arch into a forward trimmer section and an aft helmsman zone. Foot straps are mounted for crew hiking, needed when the boat heels hard on a pressed-upwind racing crew of two or three. The deck-stepped mast is easy to haul and derig, and the beam sits far below road-towing limits, making the 1,450 kg hull genuinely trailerable.
Rig and Handling
The fractional sloop carries one foresail and a symmetrical spinnaker of 36 square meters, with a large main and powerful battened jib driving her. She will get going in as little as five knots of breeze and was originally designed for fast sailing, remaining a fairly fast boat for her size. Owners report taking her out in 50 knots with three reefs and a storm jib, and the class authority notes she is safe in rough sea, strong wind, and even gale with no danger of capsizing. Writing in Yachting Monthly, reviewers found her a rare combination of elegance, excitement, and the sea-keeping ability of a much larger boat anchor, equally suited to competitive club racing or fast passage-making.
Accommodations
Below, the H-Boat trends toward camping rather than coastal caravanning. The coachroof windows and large forehatch flood the white gelcoat interior with light, though the fit-out is not to modern new-boat standards. Two side bunks in the saloon sleep adults, a forward V-berth matches the size found on the First 27 SE, and a tester counted four adults resting comfortably. Sitting headroom but no standing room defines the low-freeboard coachroof, and a portable-toilet compartment sits under the entryway behind a modesty curtain — a privacy limitation a reviewer called a dealbreaker for couples wanting enclosure. The deep bilge serves as stowage, forward worktops hide drawers, and the veneered bulkheads lend a classy note to an otherwise spartan interior that still holds everything for a comfortable short cruise.
Known Issues
Period reviews flag a wet ride and the lack of a furling headsail as class foibles, alongside awkward outboard operation that owners report makes control in port difficult. Anchoring is a bit of a faff: the large Danforth lives in the lazarette with chain in the bilge for weight, though deck mouldings exist for a windlass and hawse pipe. These shortcomings can be rectified with moderate investment.
The Verdict
The H-Boat is a enduring one-design that delivers big-boat sea-keeping in a trailerable 27-footer, at the cost of privacy and modern interior polish.
Pros
- Proven racer-cruiser with active international one-design fleets

- Trailerable, deck-stepped rig, self-bailing cockpit, spade rudder agility
Cons
- No enclosed head; portable toilet only with curtain privacy
- Wet ride, no furling headsail, awkward outboard control in port
- Spartan interior below modern new-boat fit-out standards
