Are you going to use Globalstar? I found that it works well offshore, but not so well near land when you are using distant satellites. They are low orbit and easily blocked by buildings and hills.

Tony,
Have a great sail. Keep us posted on your progress!
Will you stay offshore the entire way or go through the inter-coastal? My preference is off shore, but you need to watch out for Cape Hatteras - it can produce some mean waves!
Take care and have a great time!
Eric
