Prices and stock are live from our catalogue.

Harken part numbers cross-checked against Harken's published one-design deck layout for the Club 420 (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 Club 420. 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 Club 420?

Each part here is linked to the Club 420 because its exact manufacturer part number appears on the Club 420 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.
