anchoring in water 500m+ deep

Its so simple, you buy a trawl like fishy boats do you then chuck it over the blunt end, using your octopussy ropes
mit baling twine attached to various bits of chain, now
heres the clever bit TCM, then you proceed to the 500 metre
bit and like all trawlers you trawl up and down until you
"Come Fast"(Fisherman knows what i mean). Now you are
firmly anchored, you can break out the G&T's and start
bobbin up and down like this.you can practice the hornpipe
safe in the knowledge thats there is no one else daft enough
to be out there, who might see you
When its time to leave, you merely attach a large dhan
buoy to anchor line and cut loose.
Then in future you will always have your very own mooring.
OH! OH! word of warning don't trawl in submarines lanes
So you see it only required lateral thought
Cheers Tony
 
Or simply moor in company - tie your sterns together with a few yards of rope and set your autohelms to opposite courses then adjust throttles to lowest possible speed that keeps you both still.

Make sure your boat is the one facing the wind. Nothing can go wrong.

Odds are, if you lay a mooring, every time you pick it up some little jobsworth in a dory will appear and ask for 20€ mooring fees for the Crown Estate.

That's the beauty of a mooring - I have assumed in 500 m of water it will be more than 3 miles offshore, so international, so no-one can claim any money from you! And I would not recommend a sinking bouy - with all that chain and rope underneath you will need an enormous bouy to support it - so the bouy will be big enough to write all kinds of warnings about it being private property etc. On second thought, maybe you should stencil "Property of US Navy - unathorised users will be shot, bombed and sent to Gitmo" on the side. That will keep the riff raff away.

But personally I would still try to find a pontoon.
 
Just remember that, once you have dropped your hook, you can gaurantee that within half an hour someone will come and park up 20 metres away from you.

You'll then be able to compare notes on deep water anchoring!
 
One engine running, full right hand down a bit boat goes slowly round in circles.

Just wait of it coming round next time.


Mmmmmm

Praps not
 
I think the question you are asking is - how do i set an anchor in this depth?
In my experience an all chain affair is much preferable and reduces the tendancy to swing enormously. Iam sure that you should consider two anchors perhaps using your kedge astern to ensure a fixed position and minimal swing. This will ensure that you are always bows on to you chosen horizon.The kedge could be on a suitable length of good multiplait with perhaps only the usual say 10% of chain say 50m.It may be wise to lay the bower anchor first before rowing the kedge out in your dingy.A reliable out board for your dingy may be useful for this since you may have to row upward of a mile to drop your kedge at a good extension .REMEMBER to hoist your black ball to show that you are at anchor and shine your all white anchor light at night.
good luck

5 x depth

i disgaree. Surely, to anchor in 500 you don't need to have over a mile of rope/chain lying on the seabed. Bearing mind that the orientation of the rode from boat will be essentially vertically downwards for the first (say) 400 metres, ish.

500m of 20mm polypropylene weighs 100kilos, the weight of another person on board.

[/ QUOTE ]I think you need some lateral thinking. There are virtually no currents in this spot (??) so all you need to do is get the windage down. Just open your sea-cocks and allow the boat to ALMOST sink! Very little will show,and you did say you could put up with a bit of drift /forums/images/graemlins/tongue.gif
 
Re: 5 x depth

Fascinated as to why you want to anchor in such water. Imagination is going wild thinking of sunken treasure and a small ROV! As for coiling it up, just flake it into a plastic dustbin or two.
 
You could try contacting Cousin Trestec . Although their yachting ropes come in the usual 100m reels (some up to 300m - smaller diameters) their web site claims their military ropes come in lengths of "several dozens of kilometers". That should be enough! The down side is they don't say what diameter/type these are.

They used to have a distributor in Taunton but since they are a French company they would have a supplier much closer to your boat.
 
Truly 3-dimensional thinking suggests the answer's a submarine, then you can park it more or less where you like. Ideal for avoiding those Mediterrenean storms and overnight berthing fees.
 
Your somewhat generous rule of thumb for calculating the amount of anchor chain to deploy doesn't work for deep water. How much you need depends on a lot of factors, but IMHO 5 times is way too much in 100m of water. Depending on the circumstances and tackle deployed, you might only need 1.5 to 2 times the depth.
 
Taking three dimensional thinking more literally, all that's needed is a tanker load of aggregate. Find location for anchoring, request tanker unload aggregate so that it forms a neat pile on the sea bottom, the top of which should be within normal anchoring depth. Drop anchor in the usual way. Simple, eh !!
