The 2003/4 Dayskipper pack does not contain a CD whereas the 2004/5 pack does and contains specific exercises relating to the use of chartplotters. The CD contains two programs - the Admiralty Chartplotter & the RYA training programme.
All of the packs we have bought recently are 2004/5 so the clear intention would appear to be to not use last years versions. I suggest that you call Phillipa Donne (Philippa Donne, Cruising Scheme Administrator, Direct dial: 023 80 604183, Direct fax: 023 80 604288, Email: email@example.com
) at the RYA who runs the scheme. She will have the definitive answer.
