Earlier, I mentioned a book by Frank Rosenow, and the obvious design influences derived from 
the Swedish eka working boat. There is a further bit of design heritage in the Passagemaker dinghy that should be mentioned. The famed small boat designer Sir Jack Holt also had his role influencing the design of the Passagemaker with his Mirror racing dinghy. This role is acknowledged by the Passagemaker designer himself, John C. Harris, who says, "Both the Mirror and the Passagemaker are prams with gunter-sloop rigs, which is sort of my wink-and-nod to Holt." Indeed, the economical 
gunter rig is found in both boats, combining a fast, weatherly Marconi-style rig with the convenient short and transportable spars of a gaff rig. But beyond that, the serious racing purpose of the Mirror is apparent: the design sports a finer bow, a planing hull, and the more complex and versatile running rigging of a class racer. Many mirrors are also equipped with hiking straps and trapeze wires for hard sailing, in contrast to the simpler, all-purpose configuration of the Passagemaker. Large numbers of Mirrors exist today, and Mirror clubs are active in England. There, the fine art of dinghy sailing is refined, and subtle points of rig tuning discussed. Passagemaker builders have Jack Holts Mirror dinghy to thank as another design influence.

As mentioned at the start of this project, the Passagemaker dinghy design is inspired by a traditional Scandinavian sailing pram. Today I received a copy of the out-of-print Sailing Craft by Frank Rosenow. This literary study of Swedish working craft of the 30s 
and 40s depicts the lineage of the Passagemaker dinghy. A ubiquitous Swedish working boat, called an eka, is perhaps the father of the Passagemaker. The version that Rosenow describes is slightly bigger, at about 14 feet LOA. But the design influences are unmistakable, with the characteristic snub bow, and lapstrake hull. Some minor differences include the ekas raked stern transom, and a Marconi rig that contrasts with the sliding gunter rig of the Passagemaker. When my own copy of Passagemaker finally takes to water, I will have Rosenows book to remind me of the rich history of its simple, elegant design.
