Permanent mooring into rocky lake bed

Re: Permanent mooring into rocky lake bed

Our yacht club regularly creates public day moorings in remote rocky areas by filling plastic 45 gallon barrels with concrete and attaching your standard mooring set up to those. We know two fellows who moor their 30+ ft vessels year round using a series of concrete cast highway dividers (available through most large ready mix facilities eg Lafarge) that are chained together. The chain is then attached to a standard mooring set up and divers inspect the setup annually for wear, rot, and chafe. You'd just have to ask a knowledgeable person how much weight you'd need for your particular boat in your particular area. I think each concrete precast divider weighs about 600 lbs and I know for sure that the guy with the lighter of the two boats uses three of them.

rbh, I suspected that once you put 90psi air to it, it'll remove any water that may have worked it's way into the tool.

A quick search on a couple of SCUBA forums found a few hits indicating that there isn't any problem using standard air tools under water, just make sure you dry them when you're done, and it's recommended that olive oil be used to lube the tool since it's biodegradable.

Salt water.. they'll work... just not as long.

If your rock slabs have spaces between them, it may be possible to locate a joint with favorable geometry and stick an air line in there to clean out the debris.
Place one or more of your Helix Anchors in to the space and then backfill it with concrete.
If moving 3 or 4 of the slabs would be required to pull the plug, it should hold.

Made a driver to remove the shift shaft seal today to whittle away at the boat issues between times I can work on the mooring issue...
