Hi Marc,
What we are looking for is a good division of North America that groups likely multihull sailors. Color is not an issue.., forget that. This is just a gif trying to show the lines of division.
What we need is input by the mulithull sailors out there on what they think the division lines should be.
Naturally, anyone can cross the line to sail in another region, just as in any class or even US Sailing.

And we wanted to keep the number of regions low, i.e., we could divide into 25 or 30 regions.

Please keep the input coming. We need your help.
Thanks
Rick
