Did you say seastead? Welcome to the seasteading movement. I’m sure you’re familiar with The Seasteading Institute and Blue Frontiers. There is a group called New England Seasteaders you may want to check out. They have regular meetups in Boston, Portsmouth, and other parts of New England. http://NESeasteaders.org
I’m already seasteading. Since December of last year, I’ve been a full-time cruiser and liveaboard on my sailboat. Patiently waiting for new seasteads to open.
