John,

I've known people that have made that trip with a watch set to greenwich
time and a small hand held AM Portable radio to home in on Bermuda's
radio broadcasts.

They sailed south on the LNH until picking up the local broadcast from
the Island

It is around a 900 mile trip, roughly a week to ten days. Refrig helps
if you want fresh produce but setting up for cruising rations isn't that
hard to take for that lenght of time

OT
