Hey guys. I bought a box anchor and don't want to lose her. Which type of rope do you use for your anchor? And is there any sort or minimum width I should get?

I guess while I'm at it I might as well ask what type of knot you guys use?

Of those two materials - nylon.

If you have access to it - amsteel/dyneema etc. are pretty nice.

Knots - if you are doing an anchor i'd get a line with a spliced in ferrule end, then use a clevis.

If not that then you'd want to do something like a figure of 8 and burn whip the tag end.

I believe they say 3/8 for boats up to 26ft as a guide. You should base it upon the weight of your boat and the conditions you will encounter; 3/8 will most likely do the job and not be too big. An anchor line with factory eye-spliced with a thimble is nice.

Example: http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?productId=99811&catalogId=10001&langId=-1&storeId=11151&storeNum=50304&subdeptNum=50305&classNum=50306#.UVfJvRw3t8E

You should attach the anchor to the rope with a shackle. Don't forget to use the safety wire.

Example: http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?productId=102174&catalogId=10001&langId=-1&storeId=11151&storeNum=50304&subdeptNum=50331&classNum=50333#.UVfKRBw3t8E

If using a knot, I would use the anchor knot: https://www.google.com/search?q=anchor+knot&hl=en&tbm=isch&tbo=u&source=univ&sa=X&ei=_cJXUZSPOIa7igKOm4GYDA&sqi=2&ved=0CEQQsAQ&biw=1920&bih=1075#imgrc=7e720qNe5Z5c_M%3A%3BuOUDilzOBLTiFM% 3Bhttp%253A%252F%252Fwww.anchoring.com%252Fimages% 252FArticles%252FThe-Best-Anchor-Knot%252FAnchor-Knot.gif%3Bhttp%253A%252F%252Fwww.anchoring.com%25 2Farticle_info.php%253Farticles_id%253D7%3B500%3B2 89

They say the scope for a box anchor is 2:1 (50ft of depth = 100ft rope). Although I have had good luck with such scope using the box anchor, I still carry 100ft of rope even though I only anchor in shallow water (In deeper water I just drift). Higher scope only helps.

Honestly, at this point I mostly just use the 50ft anchor buddy. I mainly seek shallow (somewhat) protected coves to anchor in.

You are going to love the box anchor. They are great. I swear by mine.

After using anchors like this as a kid, I have come to appreciate a good anchor.

Those look like the anchors I made for my first slalom course back in "62". Worked well for the bouys, but the fishermen kept snagging the line and dragging them out of position.

Looking for new anchor line myself. I got a new anchor from my daughter for Christmas with a 50 foot 1/4" line.

The problem is the last anchor was lost because we had a 50 foot line and threw the anchor in where it was 60' plus deep.

Forget to tie off the anchor line before throwing the anchor over board? Or did the 1/4 line snap?

Nylon is stronger and more abrasion resistant than poly.
I avoid the floating poly because in party lines etc when the boat changes direction and a line goes slack, the excess line floats on the surface. This is prime to wrap in a prop of yours or some one passing too close.

My choice is 1/2" x 150' minimum. It is not that much more expensive than half. If it becomes a little damaged it is still plenty strong to do the job. 3/8 or god forbid 1/4 is compromised much sooner.
If caught in a prop the larger diameter will usually wrap up and kill the motor so the jackazz can not get away with a dumb look on his face as happens when smaller line is cut. Once wrapped it is easier to unwrap than thinner line.
Why 150'min? too many examples as to why 50 or 100 is not sufficient for normal use. Then factor in the occasion the boat breaks down in deeper water and you need to anchor before blowing into shore or visit a different lake with deeper anchorage.
Always entertained when we go to LOTO. It is a deeper lake for several cove out locations and especially Shootout where depth is 60-100' See tons of people with lines straight down because they don't have enough and wonder why they are drifting........

Thanks for the responses. I know that the box anchor doesn't require a chain, but would it hurt to attach one just in case?

Hogwild - the chain never hurts.

Chain acts like lots of extra rope, the design of a box anchor is to allow a higher angle to the line, but in marginal set ups some good heavy chain reduces the angle of pull on the anchor.

Its a pain to stow though.

I'm getting ready to buy a new anchor line as well and was thinking about using this to attach my box anchor to the line.

I use an anchor buddy clipped directly to my box anchor. If the water is over 10-12' deep, I use an extra 30' of Nylon from here (http://www.mooringlines.com/anchor_lines.htm) to make up the extra distance.

You would need to get a very large one to accept the protective line thimble.
I am guessing you are trying to keep it one piece to avoid losing the shackle pin because you want to separate the line and anchor?

A shackle like this is more appropriate http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?productId=102174

The protective bag that comes with a box anchor is large enough to contain both anchor and 150'+ of 1/2".

I am all for using this it's a 1/3 the price. Would you get the 1/2" to hold 4000LBS? That should be more than enough, right?

I think most well made will work and capacity will not be an issue.
A shackle opening large enough to fit the thimble though with plenty of swing room is usually the determining factor.

Unless you are looking for SS, most hardware or farm supply stores will stock galv which works fine and is stronger than SS. If you are hung up on SS for some reason, use the others as a guide for what size is needed.

I just wonder if farm supply places will have the nylon as well as it seems you pay a premium from buying from a "boating" site?

Edit-I did find some 3/8 nylon at academy sports (100ft for $25) but it comes with a plastic thimble so I may have to replace that if I stick with this rope.

Not to be construed as an endorsement...;)

Although I would support buying local, pre-spliced with a quality thimble is hard to find at anything but a marine shop.

I think you guys may be confused with my response. Galvanized vs SS was only in regards to the shackle that will attach the anchor to the line.

A properly eye spliced anchor line is important if you don't want to unexpectedly leave your anchor on the bottom from a knot releasing or line breaking due to chaffing at the knot.
A metal thimble is preferred over plastic from a durability standpoint since plastic will tend to wear faster and crack or break under pressure but its not critical. My largest anchor line is galv, two others are plastic. If they are not going to be exposed to the sun constantly like on the bow of a cruiser, I would not worry.

Where you can purchase largely depends on location. Osage Beach, Lake of the Ozarks, Walmart has a year round boating section that is impressive by any standard and grows in the summer. Most every place has some kind of boating gear.
If you don't live by water or at a small marina, you might have one or two choices at high markup. I like to buy local but regard these places more as a convenience store for last minute or emergency purchases, not regular needs.

My recommendation would be more along these lines (pun intended)-

I guess the other question I would have then is what's the difference (which is better) between twisted and braided nylon?

I found a great site in my search. It seems to have decent prices as well. Thought I would pass along.

That is more of a yachting website but it will work.

Line strength has as much to do with raw materials used as size. Look at 1/2" line by generic imports, common mfg like Seachoice, and quality cordage by Yale or Sampson. The quality of raw material, density and actual thickness is noticeable. Rope is not just rope, just like a boat is not just a boat if you have specific needs.

I prefer double braid nylon over twisted strand for general anchoring. Double braid gets its strength from the inner strands while the outer covering is more protective.
Twisted has the strands exposed so as those are damaged, the line will lose strength. In general too, especially with the lower quality twisted, the fibers will have a greater tendency to snag which leads to frey and compromise.
Twisted is generally preferred by the cruising set for anchorage because it has more stretch which is desirable for overnight and longer anchorage, especially during a storm of surging seas. This stretch acts as a shock absorber to lessen the jerking on an anchor that might lead to it pulling out.
For our smaller boats with relatively shallow anchorage over short time periods; if the anchor is not holding it is either under sized, under scoped or not set properly.

Anchor Buddy: 14-50'
Anchor Buddy shallow: 7-21'

With a 2:1 scope recommended with the box anchor (more = better) the short would be good for up to a depth of 10.5 at maximum stretch. You would not want to be at maximum stretch all the time (no where to go when the boat needs more which means anchor will drag at that point defeating the purpose of the anchor buddy). While Sodar pointed out you can attach a line to get more, do you want to always be doing so? So the short may do you if you are always in shallow places like the delta, in lakes with steeper banks you will want the longer version. With the normal version you will be able to anchor farther out which means more protection from the shore for the boat. For the few extra dollars the normal version is the best. JMO.

So could someone tell me the purpose of the safety pin on this shackle? I mean i could understand if it were on the other end but im not sure how putting a safety wire in the twisted end helps. What am i supposed to tie the safety wire to? Someone please enlighten me?

Run the wire through the hole on the pin and back around the Clevis main body and twist off like a bread tie. It will keep their from working it's way loose and coming undone.
