Don,
It is good to have a dream to share love of people and the planet!
A like-minded soul is Steve Roberts who builds devices for travel while communicating using techno-sustainable devices such as recumbent bicycles

He's located not far from you and he might have some good tips on how to best follow your dream of yacht travel while communicating with the world.
