Shields One-Design, Cornelius Shields' Gift to American Keelboat Racing

A famous sailor commissions, and gives away, a class

Most brand pages on this site profile a company. This one profiles a class, named for the sailor who funded it. Cornelius Shields, among the most celebrated American racing sailors of his day, went to Sparkman & Stephens in 1962 wanting a glass-built successor to the wooden International One Design that dated from the 1930s. Olin Stephens' office answered with its design number 1720, a narrow, open, heavily ballasted keelboat with long overhangs in the classic S&S idiom. The model page carries its full dimensions.

The first batch, numbered up to 31, came out of Cape Cod Shipbuilding and went straight to East Coast universities as gifts. Shields kept giving, eventually placing over a hundred boats with college sailing programs, a group of them in southern California, and sailors attached his name to the class to honor that generosity.

Three builders across six decades

The builder of any Shields can be read from its sail number. Cape Cod Shipbuilding produced the earliest block, Chris-Craft Industries turned out the large run of the 1960s that makes up most of the older fleet, Hinckley contributed a short series of about a dozen, and from number 201 onward building returned to Cape Cod. Counting replacement numbers assigned after a fire claimed the Naval War College's boats, around 260 hull numbers are on the books, and Wikipedia tallies 259 hulls. Cape Cod Shipbuilding, a Wareham, Massachusetts, family firm whose sailboat building goes back to 1899, still offers the Shields new.

The Shields 30 is the model we cover. It has no cabin, a teak-trimmed open cockpit and class rules, including limits on new sails, that keep costs down. Those rules work: Karl Anderson won the 2026 National Championship at Oxford, Maryland, in Shields 235, Harrier, and restored Chris-Craft hulls from the 1960s still race on equal terms.

Finding and judging a used Shields

Secondhand boats change hands mainly through the class association's site and word of mouth among fleets, not through yacht brokers, and prices stretch from a few thousand dollars for a project to near new-boat money for a modern Cape Cod hull ready to race. New England holds the biggest concentration, much of it Chris-Craft built, with further fleets on the Chesapeake, in Texas and in California. Because Cape Cod Shipbuilding still sells parts and offers storage and repair, owners of a 1962 design enjoy better factory backing than many owners of far newer boats.

Spend on a sound hull and good sails rather than a newer year.

• Soft or wet coring in deck, benches and coamings
• Keel fastenings and the joint where lead meets hull
• Mast step position against the class calculator
• Under-seat flotation tanks
• Rudder hangings on the keel and the tiller head
• Class-legal sails and the state of the trailer
