In describing your "It's Not A Race" event (which I provided on YouTube) ,
"Safe" Boaters of New Hampshire described your boat as a 31-foot Sonic emblazoned with racing checkered flag graphics. Anyone boating from Welch Island to points south can see it prominently moored off Rattlesnake Island. (Or hear its peculiar noise while visiting Keewaydin Point).
Take complaints to them.
Factoid: "Surface-piercing" propellers date back to 1927.
