Len,
You must have known that I have just pulled my Corri ashore!
From front of bilge keel to pointy end is 9ft 9", keel heel to stern is 7'9" neither measurements include pushpit or pullpit. keels are 4'9" across at widest(centre). Just for info. keels are 3'9"in length along bottom edge.As you will see this totals to 21'3", which is about right.Good luck with the trailer.
As for the COA I hope they are still going as they take my money! Have you tried their web site for a direct line via email, use a search engine such as google or hotbot(seriously!) for the address.
regards...Derek
