Good memory Tis. Here is the Marine Patrol position regarding home made markers.
The New Hampshire Marine Patrol takes a lot of
initiative to ensure public bodies of water are adequately marked for safe
boating; so you are correct that "private" markers are not approved on navigable
waters across the state. Typically if a "home-made" navigational aid is located
it is removed. While the intention is good, to your point, if everyone took it
upon themselves to "courtesy mark" what they perceived as a navigational hazard
may cause greater confusion to those trying to navigate an already precarious
body of water.
If there is concern that an area needs to be marked differently than it
presently is we encourage folks to contact us. On occasion we do add
navigational aids or have moved existing ones that may have come off station due
to ice flows or tampering.
Of course we always encourage boaters to use a navigational chart and to take
advantage of the many electronic devices available to ensure safe boating.
However most importantly folks need to slow down and not boat faster than their
knowledge and abilities allow.
Please don't hesitate to contact me with any further questions - respectfully,
