Get the boat you want,
Have a trailer made by somebody like Triad Trailer,
Sailboat Custom Built Trailer - Triad Trailers, Inc.
Tow the boat with your truck,
Launch with a crane at a marina, Step the mast with the same crane.
You can tow it and stow it anywhere you want to, but to think that you are going to launch and step a fixed keel boat with 5' draft and 30+ foot mast all by yourself is very wishfull thinking.
