I'm gonna make history here, and side strongly with Bear Islander on this one.
Kayaks have the exact same rights as any other type of boat. NH law makes it very clear that the public is to have unrestricted access to the larger lakes, and does not differentiate between paddle craft, sail boats, or motor boats in that right to access.
Though considering how many snapped off Navaids I've seen lately
, if I owned a dull collored kayak and wanted to use it on Winni I'd for sure grab a can of dayglo orange spray paint and take care of business before going out!
