Promoted as having more capacity and stability than a conventional boat of equal length, HMCo. prams were particularly well suited to being carried upside down on the decks of racing sailboats. 

By contrast just a few years later, these prams were advertised for sale in a 1937 HMCo. chandlery catalog. This catalog was a new attempt to drum up business for the Company during the Depression years. The prams were advertised for $160 in 1937, when the median hourly wage for men in Rhode Island was $0.50 per hour. Whether the chandlery catalog was a commercial success for the company is not known, but with the Haffenreffer family at the helm, the Company weathered the Depression and even kept much of their crew employed, mostly through capital improvements to the facility. 

This pram was purchased by the Museum in 1978, was refinished for display in 2002.
