How do I know a part fits my H-Boat?

Each part here is linked to the H-Boat because its exact manufacturer part number appears on the H-Boat parts lists we reviewed. Fit can still depend on your boat's year, builder and rig, so check the product details and your class rules, or ask our technical team before you order.

Where can I find the H-Boat rig dimensions?

Our H-Boat Sailboat Data page lists the rig dimensions (I, J, P, E) and other published data we hold for this boat. Figures there come from a sailboat database and may differ from class measurement rules.

Can I order halyards and sheets made for the H-Boat?

Yes. Our H Boat - Halyards & Sheets page lists 28 halyard and sheet options made up for this boat.

Are there tuning guides for the H-Boat?

Sailmakers have published tuning guides for this class, including North Sails (H-Boat Tuning Guide, Undated web guide (Steffen Stegger, Lars Christiansen, Theis Palm); tension table image uploaded 2017); North Sails (H-Båd Tuning Guide (Danish edition), Undated blog guide (Theis Palm); in Danish); Høj Jensen Sails (H-Boat Trim Guide, Current web page (undated); described as the result of five years of sail and rig testing); Høj Jensen Sails (Trim Guide NL (H-Boat), Undated web page; Dutch translation by Team NED 85 with Høj Jensen's support, which says it mixes the original with the team's own interpretation (it cites 15 years of testing)).
