As Duncan so kindly points out, it would be irresponsible of me at this time to commit to this cruise next year, although I would jolly well like to be there.
Instead, please read the Trip Report, List of Waypoints and About This Cruise here:

Click on Scilly Isles 2004
This should hopefully answer a lot of questions for those who have not cruised there before.
In addition, if I can answer any questions or provide assistance to anyone planning this trip, please let me know and I will do my best.
