HMCo #1428s [11 1/2 Potter Dinghy]

"Fifty-five years ago, Frostbite dinghy racing was all the rage, very popular and quite competitive, particularly on the East Coast. Everyone was doing it, and a lot of big names were involved both in the designing and the racing of these little boats. But what had begun in the early 1930s as a loosely organized, devil-may-care, saltwater sport using utility yacht tenders, soon became expensive, hell-for-leather racing in custom machines. In an effort to bring order to chaos on the race-course, the pre-eminent yachting publication of the day --- The Rudder --- sponsored a design contest in 1934 to produce a one-design Frostbite dinghy that could race under strict rules [see Rudder August 1934, p. 34].
The competition was conducted not unlike a 'blind' wine-lasting, wherein the entries are judged solely on their merits, with no names attached which might predispose the judges. That the entry submitted by the firm of Potter & Strawbridge was, in this regard, the unanimous choice of The Rudder's blue-ribbon selection committee, underscores the achievement of this winning design. After minor changes were made to the Potter plans, the boats of this class were clinker-built of cedar on oak, with hackmatack knees, and Honduras mahogany for transom, centerboard, sheerstrake, thwarts, and trim. Spruce spars, brass hardware, and stainless-steel rigging completed these craft. Frostbite dinghy racing has declined in recent years, but fiberglass versions of the Potter design still actively race at the Newport Harbor (California) Yacht Club, where Nick Potter was a member.

As soon as the Potter entry was declared the winner of The Rudder's design competition, 24 of these boats were ordered from Herreshoff by prominent East Coast yachtsmen. Other boats were constructed (also in multiples) in the mid-1930s at shops in New York, Connecticut, Florida, Texas, and California." (Source: Skahill, Thomas G. "A Winning Frostbite One-Design."

A comparison of the two transcriptions can be particularly useful in those many cases where the handwriting in the Construction Record is difficult to decipher.
