No sooner than I think of reasons not to register non-powered boats than I pull a lost kayak out from under a dock! (Today at noon).
The dock looks long-unused and there's nobody home at the residence, so this must be an orphan from yesterday's violent storm.
It is a very light purple-gray, about 5 feet long, and marked "Nu-Nu" XL. It's a little scratched up from rubbing on the rocks upside down, but still looks shiny-new otherwise. An address label is too faded to read. I tied it on top of the dock it had foundered under.
The dock is maroon-red in color, and might be visible from the person(s) upwind location from which it came. I left some water in it so it won't get lost again from today's storm, which is thundering in the distance right now.
Otherwise, PM me for directions.
