I will be testing out the idea of using a two string kite to pull a seastead around by using one to pull a raft.    I have played with a couple small boats and kites before and think inflatables should work.     I ordered some stuff and will try it out on an 8 mile stretch along the coast of Anguilla when it gets here, about a month from now.   Could also be a good method for life rafts in general.   And maybe people getting from one island to another.   At some point I think I will try a model of a tension circle that is big enough to hold two people along an 8 mile downwind route along Anguilla.
