what type of anchor to get

[hlb]

Nothing to do with size of boat. 3 times depths is minimum chain. You can use chain and rope, but then 6 times depth.


Think about it. You need chain on the ground to do any good. Swinging about is doing nothing. So Lets say in ten metres of water. Little bit of wind and tide. Thirty meters of chain out. Theres only say 10 metres of chain on the ground. The rest is at say 45deg to the ground. Bigger wind or tide and theres nearly no chain on ground. It's the chain on the ground that stops you. Not the anchor. The anchor only holds the last few metres of chain in place. Then course. In my case, the bow is two meters from water. Or three from bottom of boat. So If it's ten metres from bottom of boat, it's 13 metres times three, minimum. So 39 metres of chain. But this is minimum. Having said that. You might manage off far less, in fair weather for an afternoon. I always let out three times minimum though.

it's the metres bit that gets me . With a 25 ft boat , why do I need whatever 90 M of chain is in english

Hib,Dave was asking about his 102' boat so he needs

thicker/heavier chain

Agree length needs to be the same and said so

cheers Joe

 

[JKay]

30 metres not 90

cheers joe

its mainly rope the now i would say max depth would anchor in would be 25-30ft

[/ QUOTE ]Well. that is why your anchor won't hold - stick about 30~45metres (100'~150') of 5/16" chain on the end of your folding anchor and try again. failing that change the anchor for a delta and keep an all chain rode paying out between 3 and 5 times the depth of water you are moored in plus 10' ~ 15' extra chain.

As previously stated you will need a minimum of three times as much chain as the depth you're trying to anchor in, but you have also got to consider how you are going to handle it.
Have you got a winch and a chain locker? If you have a winch you will need calibrated chain to ensure that it runs through the gypsy with out snagging, no winch, uncalibrated will be o.k.and cheaper.
A combination of chain and rope is a good compromise if you have to haul it in by hand.
As suggested, I think the 6kg Delta is a good all purpose anchor, I have used these many times without any problems.

If you go for 30 meters of chain you will put the boat bow down, and remember you have to haul it, go for 20feet of chain a Delta 10kg will do you and rope that you already have, you will need however to deploy at least three times the depth to get a grip.

thanks for all that so off shopping once again, anywhere should try first for the anchor/chain or they all the same prices? and its be hauled in by hand

 

[Solitaire]

Before you go running off - can I make a suggestion! I assume you have one of these?

Because of nav light configuration, you will need to stow the anchor in the bow locker and this wont be very easy with a delta or a plough. Secondly you are have to pull the anchor up by hand so too much chain will play havoc!! I would recommend you look at say a 7 1/2 kilo danforth which folds flat and say 10 metres of chain and 30-40 metres of warp. You won't need all chain on your boat! I used to keep my boat in Kip so know the area.

I had a 7 1/2 kilo danforth on chain and warp and never had an anchor dragging problem on a 23 ft boat. OK, so you may have to put down 5 times depth, but it's a dam site easier pulling up a load of warp than it is great lengths of chain and what's more you'll be pulling over the deck as you don't have a bow roller.

You'll have to pull the last bit of chain carefully as you'll scratch the gel-coat!!

Not sure why others are advocating all chain especially on a small boat. I (and most other multihull owners) use a mix of chain and rope in order to reduce weight. I looked at my normal anchor depth and selected 3 x that depth of chain, and then added another 45m of octoplait for times when I want to be able to anchor in deeper water. I suspect that you dont have an electric windlass, so you dont want anymore weight than you can carry

I hope we got to him before he left to do his shopping! Totally agree with you, or should that be you agree with me as as I posted first /forums/images/graemlins/wink.gif

 

[hlb]

Because it was only half way through the bloody thread, that we knew what the real problem was.

Dont bother with a new anchor yet, just stick some chain on it, the more the merrier! Will that do.. /forums/images/graemlins/crazy.gif

 

[Solitaire]

He did explain that he had a 23 ft cuddy in the first place, so did not take a brain surgeon to work out that it was a small boat - plus his "name" also rather gives it away! Rinker232!!

A grapnel is not the world's best type of anchor and OK so it lays flat in a small space but it's a [--word removed--] to work with, particularly when sitting on the front of a cuddy bobbing up and down trying to get the flukes together so you can lock it off!

He'll be much better off with a danforth (even a small bruce would do)as you suggested, plus some extra chain.

 

[Chas25]

Totally agree regarding the grapnel, it held my 21.5ft no problem (ever!) but was a pain pulling it in then trying to lock it of, especially if there was a bit of a swell /forums/images/graemlins/frown.gif

think I had something like 5-6m of chain... it did the job!! The thought of trying to haul 30m of chain in doesn't bear thinking about /forums/images/graemlins/crazy.gif

 

[emcm0025]

busy morning here sorry not replied still to go shopping the grapnel one held my 20ft fine but this boat, so here is choices get chain 10-20m for the grapnel one or get a danforth one with 10 - 20m of chain and same in rope views on either idea would be great help, got to admit this rinker great boat

 

[hlb]

Are we going to argue the toss all day. BOAT WOULD NOT HOLD. But it will hold with enough chain out. Now, that might be three foot or 30 metres. How the hell do I know.

I seem to have inherited, two folding anchors. So I am promoting them. OK

I hauled up 30 metres of 8mm chain, only the other week. But thats another story. Nearly killed me... /forums/images/graemlins/crazy.gif

 

[hlb]

It's all a compromise with a small boat. I have 60 metres of 8mm chain.

I used to have 20 metres. But it would not reach the bottom some places, or least, not enough of it.

Decide what depth you want to anchor in. Look at what you have now. Improve on it. The anchor dont matter to much. If a Danforth looks like it might be easier, get a bloody danforth.

3 X depth, chain is the rule. But if only stopping in sheltered water for an hour or two. Less will be fine. Maybe. In short any amount of chain will be much better than none.

Trouble is. 5 metres of chain, then rope, might do the job. But if it dont. You have to go buy some more, till your happy.

 

[Solitaire]

Let's start again!! Ignoring the grapnel for the moment, how much chain and warp do you have? Did you "swop" from your old boat to the Rinker, or was the rig already on board?

 

[emcm0025]

sorry if seeming like a right noob here, i took the rig from my bayliner, its 4kg grapnel with 60ft rope

 

[Solitaire]

Right, so now we are getting to the crux of the matter! 4kg grapnel with rope! No wonder it doesn't hold!!! Much too light and with no chain at all then you will have more chance of falling pregnant!!!

I'm surprised even the Bayliner held on that combination. Go to the chandlers, but a 7 1/2 kilo Danforth 10-12 metres of chain and 40 metres of warp.

Use the grapnel for second anchor if you like, but it's no good as main!!

The chain is what does most of the holding - without it you'll not hold a candle.
