On p62 to 76 there are codes for each boat ...

e.g. 72bfsWB or 62WBfs or 71KDfs

I guess WB = Winder Boats & KD = Kevin Driver .... but what are the other figures and letter representing?

My guess is fs = "Foam Sandwich"

Andy,

You are right. FS = Foam Sanwich, FRP = Fibre Re-inforced Plastic. Abbreviations, including these are in the year book, buried at a bottom of a page, but without the book in front of me I cannot tell you what page they are on.

Key to Designers is on page 48

When did the Mk5  Winder kick in then as they are all listed as 72bfsWB in 2006 and the key says thats a Mk4
