Eric Twiname Trust
Early last year the Eric Twiname Memorial Trust was generously assigned the author's copyright of 'Start to Win', written by Eric Twiname in 1973. Out of print for over 20 years, Adlard Coles (now Adlard Coles Nautical, part of A & C Black Publishers) have recently republished this classic - now in its 3rd Edition and substantially re-designed, with a Foreword by Ben Ainslie and an updated Rules section by Bryan Willis to accord with the 2009-2012 ISAF Rules.
2010 Events Schedule
Following the committee meeting in October 2009, the web calendar available via the menu link on the class home page http://ospreysailing.org.uk/phpicalendar/ has been updated with the events scheduled for 2010; to save trawling through the pages the list is below in one place.

The Osprey has stood the test of time, sailable in all but the most extreme weather conditions, whether inland reservoir, tidal rivers or mountainous seas. She is a credit to her designer Ian Proctor!
A well behaved and balanced boat, capable of sailing or racing with a crew of two or three, with one trapeze. She is provided with a spacious interior, with a choice of fittings and layout, rig and sails allowing competitive pricing.
One Design Class rules were until October 2005 administered by the RYA, who at this time transferred the copyright, since then the new copyright holder and the Class Association have administered the Class Measurement Rules. Although cosmetic improvements have occurred over the years, it is the ethos of the class that the hull shape and sail plan remain true to the designers original. Old boats can still (and often do) compete at the top end of the fleet. Boats built in the 1960's competing with boats of the 21st century... you may have guessed
