1938 Boston Pram Dinghy

Lent by IYRS School of Technology & Trades, Newport  RI

The pram-type dinghy, originally developed in Scandinavia, has survived as one of the most successful types of yacht tender ever built, having the advantages of being lighter and being 1 ½’ shorter than a stem dinghy of equal capacity. Buoyant and sturdy, it tows well.

The Boston Prams were designed for the builders, Mumford Brothers, Boston MA, by naval architect Charles MacGregor of C.G MacGregor, Belknap & Paine Inc. The lapstrake planking on steam-bent frames are well-formed, though not as delicate in proportion as some of the Herreshoff dinghies of this period.

The IYRS files state “This handsome little pram was originally used as the tender on the John Alden ketch HI HEELS. Donor Sam Johnson crewed on this boat and purchased the dinghy from owner Henry Perry after the larger boat was sold. This well-fitted boat is an excellent study in high-quality construction, and her lapstrake planking is exquisitely lined-off. She will require only moderate restoration to be ready for the water again.”

Wood species were selected specifically for specific structural needs and workability needed.
