About the MAYFLY
An early, light weight,low cost yet high performance dinghy. The single chine, slab sided hull simplified construction for the amateur builder. An unfinished, bare hull version was also available. Though several hundred were built and raced as a class for a few years, it seems to have been eclipsed in favor of the similar but slightly larger SEAFLY, from the same builder which sold in larger numbers and was later offered in fiberglass. An excellent web site, seaflymemories.com relates in greater detail, what is known of both boats, which today are rarely seen.
