Ok Best of Luck to all who are doing it.
This may help.
Watch out for Red Jets, day sailors and Bank Managers, they will all be in your way. Old Gaffers can't tack when you shout "Starboard", at least not before they hit you.
Go for the gap between Goose Rock/Needles Light and the Varvassi wreck, but make sure you know where they both are.
If West going tide from Needles to St Cats. Stay inside the rhum line, and therefore out of the worst tide.
St Cats to Bembridge. Stay awake. This is the most boring bit and you can make up lots of time by keeping on your toes while others doze. Use the back eddy in Sandown Bay if tide still W going.
Ryde. Don't sail into the bag in Ryde Sands or you will have to go back 1/2nm to get out. Stick to the Island side, how ever tempting to go up the Mainland shore. Don't go too far into Osbourne bay in a light S to SW'ly, its a graveyard for becalmed yachts.
Make sure all crew have a life jacket. Have been disqualified for this, but I blame the skipper. Total waste of 7.5 hrs.
The above is general guidance and should not be used for navigation, whilst under the influance of drugs or drink, or for financial gain. It has been, and still worked, but only at the right time.
