With basic sailing skills you could probably crew on a sailboat delivery across the Atlantic. I don’t think many leave from Canada or even the NE US, so low carbon would be to take a train farther South. Maybe Annapolis but more likely Florida. Look up the Atlantic Rally for Cruisers, they have a return rally in May-ish. A lot of boats will be sailing East at that time.
