General Information
The Osprey design was originally penned by the late Ian Proctor in the early 1950’s. It
was designed for the Olympic Selection Trials along with several others; two of which
became the Flying Dutchman and 505 of today. The Flying Dutchman was chosen after
winning the trials.  (Information from the Osprey Class Association web site.)

In the USA "Osprey" was Anglicized to "Ospray".

"I have just come across the pictures of your O'day Ospray. I have also noted the text
about Osprey being Ospray in North America.  This is a mistake.  Ian Proctor designed
the Osprey and it is a very different boat than the O'day Ospray, Ian's boat is over 17',
much more sail area, trapeze, different hull shape and speed.
Respectfully, the two boats are very different and in Canada Ian's boat is spelled the
same as it is in England.
Sorry to be a stickler for the details but they are different boats with different
