About the H-BOAT
The H-BOAT has had IYRU-international one-design status since 1987; It is the largest IYRU-keelboat class in Europe, and the second largest in the world.
Designed by Hans Groop and built by Artekno/Botnia Marin, the H-Boat is a compact 27.25 ft fractional sloop with a production run of 6000 hulls starting in 1967. Its lightweight displacement of 3190.0 lb and high SA/D ratio of 19.54 indicate a design prioritizing speed and agility over heavy displacement comfort.
- Best for:
- This boat suits coastal cruisers and club racers who value easy handling and performance in light to moderate winds. Its fractional rig and relatively low displacement make it accessible for single-handers or couples seeking a manageable, responsive package.
- Bluewater capability:
- With a capsize ratio of 1.95 and a comfort ratio of 15.78, the H-Boat is better suited for coastal cruising than extended bluewater passages due to its light displacement and narrow beam.
- Comparables:
- Comparable boats include other 1960s European fractional sloops like the Contessa 26 or early Oyster models, though the H-Boat is notably lighter and faster. It shares its role with other Hans Groop designs that emphasize efficient hull forms and user-friendly sailing characteristics.
