Here is a start on the question
This very subject was discussed this week in length on a local web site for the lake in NH that I sail on. I offered my opinions based on the fact that I do commercial diving to service moorings (50/yr) and that I have a 37' sailboat that is also moored there. I now feel is was trap that I eagerly fell into. They really didn't want the best advice, they wanted to be told the cheapest way it could be done. My physic sails have been shot with so many holes they may never hold air again. What a bunch of pirates, like a pack of wild dogs on fresh meat.In short here is what I had to say: My 38' sailboat displaces 18,000 lbs., my 38' kayak displaces 100 lbs. both have a 380 lb. mooring block. Which one will still be there after the storm? Are you sure you want to use that formula by the discount house? Are you sure you read it right? How much do you love your boat? There are a lot of variables when choosing the popper mooring: depth, bottom type, exposure to the winds, fetch, currents and most important the boat's configuration. Answer these questions and I can tell you what is best for you. Having said that again, I stand by for the first volley form this group. (You can skip the part about arrogance and the spelling, the other group did a pretty good job on that one)
