Temporary mooring

[30boat]

The area where my mooring has been laid is silting up quite badly and I fear that if I don't move it soon I may not have enough depth to keep the boat there.I'll try and lift the 1,6ton mooring weight but in case it proves to be impossible I was thinking of welding up a modern generation type anchor about three sizes larger and use that as a mooring until a more permanent solution can be found.I've already made copies of modern anchors that work beautifuly so that's not a problem.Would a much larger anchor be proportionately more secure,that's what I'm not so sure about.

Some of the boats in Alvor are moored to a riser leading from a "star" of 3 to 5 normal anchors. They seem to do all right.
Using one oversize anchor? I think I d prefer at least two(uptide/downtide).

So would I but I fear that in the summer when the place is much more crowded one of the anchors might be lifted by somebody anchoring too close to my boat.

What about a helix

Have you considered a screw in helical root - an adapted post hole auger even. Easy to install and reportedly excellent holding??

Not a bad idea but how is it put in place?It's not a drying mooring.

2 anchors, uptide/downtide, joined by heavy ground chain with a riser from the centre. The 2 anchors don't need to be more than a boat's length apart. That arrangement held my catamaran during the 1987 hurricane.

That's what I had in mind. Should have been more specific.

Hi Nuno,
Have you considered getting one of the larger fishing boats to do the lifting - a 1.6 ton block is better than a single anchor.

I'll try and lift the 1,6ton mooring weight

If my calcs are right, a 4ft x 4ft x 4ft lifting bag would do the job.

Our sailing club pays a local 'tug boat' to lift the heavy moorings but our little open work boat with a winch on the front and about 4 guys on board can lift the smaller ones (mid 20's ft boats) so a few quid to one of the local fishing boats etc should have it up in a jiffy.

There's a local diver who can do the lifting .I'm only worried that the area get's so silted up that it'll be impossible to extricate.

If you employ a diver it will be his problem, so no need for you to worry

I set a three anchor star mooring for my 33 foot ten ton motor sailer which stood three years of permanent all year mooring.Consisted of three 20 kg Bruces joined by 10 mm chain and one inch multiplait riser.
Sadly after three years a shackle pin dropped out on the riser-make sure you split pin shackle pin/use a nut and bolt/nylocs etc or if poss.weld pin in!
When I did it I marked out mooring with net buoys after having measured distance between with a line.I set two offshore anchors which I then connected at low tide. I then took third anchor attached to others and riser as far inshore as it would allow then as far as it would go with a line attached to its trip fastening.
Loaded the inshore anchor which quickly set in the clay sand.
In one extreme storm the inshore anchor did skip but reset itself.
