Presto!

Charlie Fuller rigging Presto at Miami YC.  Note that the foot of the sail is attached to the boom via flat lugs rather than the more common bolt rope which was phased in at about this same mid-1950s time point.  No doubt the sail is Egyptian cotton.

Clayton Fuller just emailed me two photos of his brother Charlie's Moth Boat Presto.  Presto was built in Harry Cates' backyard in Miami, Florida in the mid-1950s during the time in which Harry had borrowed fellow Moth Boat builder, Bill Lee's station molds for Bill's Mint design Moth.  Thanks for sharing, Clayton! 

 Presto bares a strong resemblance to Mint as can be seen in this earlier post. Fewer than ten boats were built to this design.
