A chap came on and asked the same question and some guys here jumped on him - not a really great response - so you don't really want to find the old thread.The guys that jumped on him are probably the same guys that post that there is no such thing as a "silly" question when newbies say they will be asking lots of questions.In BC coastal waters, there are many guides you can purchase and in them, locations with public buoys are listed. I'm guessing you have similar guides over on the east coast. If I don't see a buoy listed in the local guide books, I assume it is either private or commercial.So as an example, from the Dreamspeaker Cruising Guide, Vol 3 an excerpt about Plumpers Cove:"Anchor - Pick up one of the parks eight mooring buoys or anchor to the S or W of the buoys. Depths 6-8m (20 - 27 feet). Holding good in mud and shingle."By the way, I had to look up what "shingle" is; here is the results:shin·gle [ shíng g'l ] noun Definition: 1. pebbles: small round pebbles on a beach 2. pebbly area: an area of beach covered in shingle [Mid-16th century.
