Shields parts

Prices and stock are live from our catalogue.

Harken part numbers cross-checked against Harken's published one-design deck layout for the Shields (checked 2026-11-04).

Parts marked "Sized for this boat" are chosen from the manufacturer sizing guides published on our Selection Guides pages (Harken winch chart, Forespar pole guide, Harken mainsheet guide, Schaefer hardware chart) using the published dimensions of the Shields. They are not specified by the class rules; check your class rules for limits before racing.

Rope sold by the foot is added at the cut length shown on the card.

How do I know a part fits my Shields?

Each part here is linked to the Shields because its exact manufacturer part number appears on the Shields parts lists we reviewed (including Harken's published one-design deck layout for this class). 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 Shields rig dimensions?

Our Shields 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 Shields?

Yes. Our Shields - Halyards & Sheets page lists 25 halyard and sheet options made up for this boat.

Are there tuning guides for the Shields?

Sailmakers have published tuning guides for this class, including North Sails (Shields Tuning Guide, Undated web guide (current page; same text as a 2003 North One Design web capture hosted by the class)); North Sails (Ched Proctor) – class copy (Shields Trim Guide by Ched Proctor, North Sails One Design ('The Ched Matrix'), Updated 9/17/2003 (compiled by George Petrides, Fleet 5)). These guides belong to their publishers; MAURIPRO does not host or reproduce them, so please get them from the sailmaker or your class association.
