Be serious, guys
It's been done, though I think ar is a little late in starting his planning. It should not take months. Four to six weeks depending on destination and route. Provision for two months, say sixty days. Water would be the biggest problem in a boat that size. There are standard tables for provisioning. Don't forget that the Pardy's boat was only 24 feet, no engine. They wrote a book about provisioning for the offshore sailor but it's quite useless. Also, you can go in stages -- Bermuda, Azores, mainland Europe. And don't forget the paperwork.
