Making a mooring

If I wanted to make a secure swing mooring, what sort of thing would I need to use for an anchor point on the bottom? Somebody here has suggested a tyre filled with concrete is a common thing to use. I'm thinking maybe something like that with some steel spikes set into the concrete to grip the sea bed better, though getting it in place without punching a hole in anything expensive might be interesting!!!

Any other cunning ideas? It's a windy place and while I wouldn't want to leave the boat out in rough conditions, "just in case" it would need to stand at least 30kt without having to worry about it shifting.

Sorry if this has been covered before but I did a search, but just about every other post seems to have the word "mooring" in it

As for putting it on the mooring, do people that use swing moorings use these "mooring compensator" thingys that you wind the rope around to give it a bit more boing? I got a couple while I was away and they seem to be quite effective?

It's only a vague idea at the moment but something that I might do over the summer ready for next winter, I only rent the marina space over the summer and the options for tying up to anything else are becoming quite limited as the various old wrecks and hulks that people have been using are gradually falling into the sea! I have a mooring buoy but that is it at the moment.... any pointers would be gratefully received

Old engine blocks are quite common, don't forget anodes on the galv chain if you use it. "Lock wire" the shackles if you use them and inspect annually by diving the rig. If its in soft mud the block will sink adding to the pulling power required to move it.

mooring

Two admiralty pattern mooring anchors with 50ft of 3/4 or 1" stud link chain in between, dependant on depth of water, 5/8 long link to a swivel then 1/2 " chain to bottom of bouy, short length of 5/8" chain coupled to 1" rope with galvanised thimble to chain and soft eye sliced to samson post.

The riser needs to be at least 2 X the depth of the water, will never let go.

Steve.

I've heard broken computer monitors are good!

I use two opposing mushrooms with a swivel in the middle and a lifter set on the tail of one of the mushhies visible only at dead low, and a riser made to measure for the bay I use from the swivell (sandy bottom though) bugger me I cant lift it out some times, me old man says it would hold a 20 tonner

the tax man would be a better idea, his pockets are so heavy he could hold the channel ferry

Have a look at this site.

Fairly practical advice if it's a long-ish term mooring. NOt sure how easy it would be to lay with a RIB tho - I think a workboat is required, probably with a winch, especially for recovery.

Some interesting ideas there, I could probably get an engine block though getting it to the location might be the difficult bit, the place I have in mind, I am going to use precisely because there is a low bridge there (its an enclosed bit of water right next to where I launch) which means that almost none of the local boats can get under it to nick the mooring so it needs to be deployable from mine or from some crudely rigged barge that I can tow to the spot (maybe a couple of old oil drums or something used for flotation)

Thanks for the suggestions

The standardisation of moorings at SCYC in Abersoch are:-

-Two anchor moorings - 10 fathoms of chain disregarding strop.
-Ground Legs of two anchor moorings to be at least 15 fathoms.
-Block moorings - at least 15 fathoms of chain disregarding strop, plus back up anchor.

The moorings are laid by: - www.moorings-abersoch.co.uk - I'm sure Meirion and Owi will be happy to give any adviced you need, to contact them - details on web page

Is there a moorings company near you??
Pop in and see them if you can, they should be able to give you all the advice you need

Whatever you use why not use some big old inner tubes for floatation - when over the right spot just shoot them!!!
