Hello all! I am interested in making a reliable mooring for our C-25. One source says that 10lbs per foot of boat is needed to safely hold this size boat. Another source says that a 50lbs mushroom anchor will do the job.
I believe that the bottom condition/type can have alot to do with the type and weight of your mooring. Hard bottoms, grass, rock, etc will need more weight. If the bottom is mud so the mooring can sink in and become part of the planet, then you can get away with a lighter mooring.
Our club has made some anchors with truck tires and cement with hooks embeded in them for the mooring chain. These have worked pretty well for our lake conditions.
I have been using a 250lb-300lb mushroom on a sand bottom. I checked Chapman's and he says minimum for a 25' crusing sail boat is 175 with a max depth of 20ft. But best to check around and see what others are doing in your area. As they say location, location, location.
I have been on a mooring for 2 years now. My marina uses big drums filled with concrete. It held up until the hurricanes last year. The wave action was able to drag them to shore.
Just 2 weeks ago my boat broke free from the mooring! It was floating towards the pier when the marina folks got to it. It wound up that the clevis pin sheard at the anchor. It was all new a year ago but the pin rusted out. I guess my advice is, No anchor is too big, and check the hardware every so often.
The marina is in the process of retrofitting the moorings with screw anchors.
In coastal Maine where we pretty much have a mud bottom the recommendation by the Harbor Master is 10lbs. per foot of boat length for a mushroom anchor ie. a minimum 250 lbs. Also the rode is very important. Here the recommendation is for 1/2 " chain and twice the water depth at high tide. An excellent shock absorbing force yet not so much scope that boats require a lot of space or become entangled.
In the Falmouth, Maine anchorage we had a 300 lb mushroom, 60' of 1/2 " chain (30 ft water depth) and two 5/8 nylon braid pennants. That set up held in all weather for the last twenty years.
I should mention that the chain is lowered into the mud bottom at seasons end and it is diver inspected every other year. The chain has a life span of about three years before needing replacement.
