Why La Paz? I thought your boat was in Puerto Vallarta. Why not pick it up there and trailer it the whole way instead of sailing to La Paz. I believe there is a yard in PV that could haul your boat and put it on a trailer.
Emile's trailer might work out better than you think, for reasons that will become clear later. First, consider sailing the boat from PV to your home port. As I recall the distance from PV to San Diego is about 1,500 miles, almost all of it against the prevailing wind, seas, and current. You would actually have to sail considerably further, maybe 2,200 miles, if you sailed rather than powered. Furthemore, it is not a very interesting trip.
I think that part of the trip would take at least a month, assuming no breakdowns; maybe more. You would then have another 800 or so miles to go up the California coast. Again, against the wind and seas. The winds are light on this coast in the winter, and it would be a slow trip, especially in a Vega. (Forget the anecdotes about how Old Sally did 150 miles in 24 hours off the coast of Wherever. The Vega has a PHRF rating of 240, and I have not been able to sail to the rating in the few times I raced my boat.)
Now think about this. I sort of like over the road driving. I have lost track of the number of times I have driven across the country. I would be willing to go to Galveston, pick up the trailer and bring it to Tucson where I live. Tucson is a more logical place to start a trip to PV than San Diego. In fact, if you started from San Diego, you probably would go by way of Tucson.
You could pick up the trailer in Tucson, drive to PV, load your boat, and trailer it to your homeport. My boat is in Vallejo which is at the north end of San Francisco Bay; probably about 260 miles from where you would finish your trip. You could then drop the trailer in Vallejo, where I would pick it up, load my boat, and drive to Nova Scotia. I would buy the trailer from you when you have finished with it.
I am sure we could accomodate Dave Fuchs somewhere in this process if he has a boat to move. I don't know where he lives, but if it is out West, we could make it work.
I think Steve Burch forgets the relative sizes of England and the U.S. You could drop England (notice I didn't say Brittain) in Texas with room left over for Ireland and the Channel Islands.
