Welcome to SailNet!
There are a couple of write ups here about making the trip.
Another Sailnetter, Labatt, has made the trip in both directions with his Passport 40. Here is a link to his excellent post.
His last post here was in December, so he may not be active here anymore. However he has a blog, two kids, and a business, all of which may be keeping him busy elsewhere.
If you would like some help, send me a PM. I may be available - if I don't buy a boat, and I would LOVE to make this trip.
