Mooring

[Seapig100]

I am in the process of setting up a mooring for a 1969 45c. The location of the mooring is fairly exposed to a northeast wind. I am installing a helical screw and have been in contact with the company that makes the screw. They are recommending a three disc 12 foot long screw. I am looking for input on what size chain to use. The company doing the install has recommended 3/4 inch chain, however all I keep hearing is that is a heavy boat and I don't want to undersize the mooring.

I have called the harbor master and left him 3 messages over a 2 week period with no return call. This is frustrating as I am supposed to contact him prior to installing a mooring. The yacht club has told me it is normal for him not to return calls smh. So I sit in limbo looking for guidance outside from the guy installing the mooring.

I don't know much about the Screw type mooring, or how it is screwed in. I would be concerned it might screw out?

What is the motivation to use the screw mooring?

Have you considered an mushroom? 500#s would easily hold a 45 in a mud bottom.

Mass law states that screws are the preferred method.

My 46C has been on a mooring for 8 years. I use a concrete block (1 cubic meter about 3 tons, 2 tons in the water but its stuck in the mud.) I use 20 feet of three quarter inch high carbon chain on the ground, then a swivel, then 15 feet of five eighths lift chain ( the average depth of water the boats in ). then I have a small raft as a mooring float, which has a swivel thru it so the mooring pennant's are attached to the top where they can be seen easily. my pennants are 16 feet long ( approximately two and a half times the height of the bow ) I use three inch lifting slings as pennants. They can be dropped onto the raft so as not to get wrapped around the mooring when I leave the mooring. The boat can be subjected to up to six foot swells, large waves and up to 45 knot winds. Max tides 6 ft. It's always great to go bigger, but I thought my anchor rode is only 3/8th chain

Have fun, P

Thank you.

Can you use the screw and a block? And Tie the two chains together for additional safety?

I don't know. I know you can have more than one screw so I don't see why not.

One helical by itself should do:

So the harbor master contacted the yacht club today. He is happy with the screw, he wants 10' of 1 inch chain then the rest 3/4 inch. I contacted the company that makes the screws and asked what prevents them from backing out (unscrewing). He said the shackle for the chain rides on the shaft of the screw between two disks allowing the chain to rotate freely. The mooring is going to be installed 3rd week of May and I plan on bringing the boat home the first week of June.

When that screw is set, friction will keep it in place. It won't be going anywhere.

Just make sure they aren't screwing with ya and try to screw you!

5 years in the navy and you come to appreciate being screwed!
