splice them

Tue, 2013-06-18 19:37

 you may have to thin the strands down but a good splice always worked for me.Is it going through a winch? If it is its about the only way.The other way is to put a short piece of chain between the splice that gives the winch a chance or you to have something strong in between.

No winch

Tue, 2013-06-18 19:40

 No winch, the first piece is joined to 3 meters of chain. That is 20 meters the other one is 250 meters long and is 6mm, the first length looks like it is about 12mm.

Get rid of the 6mm

Tue, 2013-06-18 19:44

 Thicker rope is better to pull and less likely to snap.250m is a heap of rope on the anchor ,I hope you use a bouy?

Haven't used

Tue, 2013-06-18 19:47

 Was just wondering, picked up a new coil of rope at a garage sale for $5. Just throwing some ideas around, would not use the whole 250m.

Do you have a second anchor

Tue, 2013-06-18 19:52

 I have two anchors ,one on the winch and one I take up the beach when I want the arse towards the beach.My second rope is about 20 metres maybe its a idea for you.

That's some serious anchoring

Tue, 2013-06-18 19:58

That's some serious anchoring depth ability and the majority is 6mm with no winch??? That'll be fun to pull.
Suggest splicing a small eye in the 12mm then using the 6mm tie a double sheet bend. Splice the tag end of the 6mm back into the standing end of the 6mm. That ain't coming apart.

6mm?

Tue, 2013-06-18 20:12

What size is the boat and anchor?

 

My first thought is that 6mm for an anchor rope is a bit light and not worth the hassle or risk..

4.85m fiberglass

 Not a very big anchor only for sand might look around for a witch I think.

Unless it's nylon,

Tue, 2013-06-18 20:17

Unless it's nylon, spectra/dyneema etc.. which I very much doubt at $5 for a coil then I'd be very wary of relying on it unless your in a dingy and/or you do not leave the boat unattended at anchor. You really should find out the braking strain and then consider your boats weight before you consider using it as your boats anchor rope. Silver rope ~300kg, Poly ~500 kg if nylon ~1300kg spectra/dyneema even higher.

Top of me head. The point

Wed, 2013-06-19 23:06

Top of me head. The point being - don't trust ya boat & life to a $5 coil of rope. But you got me thinkin' so checked Donaghys and I'm a bit out - 6mm poly ~750kg and 6mm nylon also ~750kg. The nylon I had 1300kg in my head but that's for 8mm BS as that's what I just fitted to my winch. So correction, Silver~300kg Poly ~750kg Nylon ~750kg and Spectra/Dyneema ~3200kg and that's from a reputable supplier, if using cheapo I'd reduce these figures.

 hehe just checkin.....also

Fri, 2013-06-21 09:14

 hehe just checkin.....also depends on the length of rope aswell doesnt it??

 

But non the less your right. If you didnt take that coil off rope off the shelf at your local marine shop and open it yourself I wouldnt be trusting any SWL eritten on the side....that coil could off been sitting in the sun for 5 years

6mm rope

Tue, 2013-06-18 20:36

6mm rope should be used for hanging a net, not for anchoring any sort of boat.

I would be using not less than 10mm on a boat of around 4.5 to 5.0 metres and one bit to remember, the regulations are that you have carry enough rope to be able to anchor in the area you are fishing. Example---fishing in 100 metres of water equals 150 metres of rope minimum.

Tue, 2013-06-18 21:10

 You'd want a bit of chain if you expected the anchor to work. I thought 3x the depth of the water to anchor affectively.

Have chain

Tue, 2013-06-18 21:24

 Not using 6mm rope did not think it was a good idea, always heaps of knowledge that is shared on this site. That's the good thing about it, thanks for all the help.

Sorry Ol Yella, should have

Wed, 2013-06-19 12:19

Sorry Ol Yella, should have been a question mark at the end of my previous sentence.

On my boat, i have 50m of line nylon. It starts as 14mm for the first 5m (for chafe resistance, then goes down to 12mm for the next 5m, then 10mm for the remainder. Nylon is nice and stretchy and wont jerk. I was lucky that i worked for a supplier and was able to get the rope very cheap

I think the rope you were talking about is double braid rope? I guess it would be OK for a tinny in light wind, or for a beach anchor, but if you ever got the pick stuck, i wouldnt put money on you getting it back again.

 

Ref my previous comment, the safe amount of rope for anchoring is 3 x the water depth. If you are in really good ground then you can get away with less. Personally, i have had 50m out in 5m of water at the top of dirk hartog island once. Two anchors in and we still dragged.

hey Swampa do you use chain,

hey Swampa do you use chain,  if you are pulling in 5m of water sounds like your chain is not sufficient.  (with enough chain the 3 x rule goes out the window)...within reason.

Stapeling

 I saw a repair of some Qantas wiring done O/Seas and they just stappled it,lets face it,if it works for a passenger jet,why not a rope.
