Anchor chain combo

Hello to all,

First I am not trying to start any debate on anchoring as I know how that can evolve. I am curious as to the anchor / chain combo people are using on their PSC 34's like I have.

Currently I am using 180' of 5/16 BBB with a 45# CQR.
Been thinking about upping to 300' of chain and possibly routing the chain aft to a locatoin under V birth. Or maybe simply to the chain locker.

I'd be curious as to any FIRST HAND KNOWLEDGE of this amount of chain stacked up in the locker. Also any FIRST HAND KNOWLEDGE of any difficulties with an electric windlass stacking this much chain in PSC 34' locker.

Thanks to all!

We have 200 feet of 5/16 on our 34 and when I put in all back in recently after marking the chain, I had to adjust the pile in the locker. It would pile up too high to fit more chain without pushing it around to make room for the drop of more chain. Additionally, the chain locker divider has been cut back slightly and covered with a heavy duty wire reinforced rubber hose split in two to help protect the divider from wear.

Keith,

We cut back from 300' of 3/8" to 240' for a few reasons: save weight, make it stack below the pipe and because we were never using more than 240' anyway. You can shorten scope to 3 to 1 when you anchor deeper than, say, 50' (see Eric Hiscock, Miles Smeeton, etc.). There is so much weight out there you will never lift the chain behind the anchor off the bottom, although you will lift 5/6" closer to the hook than 3/8". I have always based my choice of chain size on weight, not strength. If you have the weight, the strength follows, especially with HT, though BBB is fine.

Since we rarely use more than 180', even in coral waters, we put the first 60' (10 fathoms) on the port side of the divider and the rest in the main part of the locker. Our 180' of 3/8" stacks with no problem that way. If we use more than 180, it draws from the port side and we have to lead it back to there when weighing, but this is rare.

One other tidbit: if you sail the hook out in any kind of breeze, the chain will not stack, but this is not always possible.

As to electric windlasses. Can't say. I took the electric windlass out when we bought the boat and put in a Muir manual. Never gets hot.

Just the kind of info I am looking for

Thanks so far guys!
This is exactly the kind of info I want.

Dave,
Not sure u remember me. I'm the fellow who purchased Mike Chings boat up in Ventura. Was having trouble on maiden voyage deploying Jib. U were kind enough to help.

Thanks and please keep the input coming.

As I haven't looked very extensively under the V Birth I'm not really sure what I'll see. I know I have a holding tank on port side and a water bladder on stbd side. Does anyone know if there is room for anchor chain storage if routed in a clever manner?

Am I the only one to think that for general use 180' of chain on a 34'er should be more than adequate ?

On Raven (34' 6.5t) we had 35m (115') of chain. I would have gone to 50m (165') in the long run but I don't see that for her intended purpose I'd ever need more than that. Yes, it would be nice to have twice that but you surely need to draw a line appropriate to the size of the boat.

tdw-

I am quite sure you are not the only one that believes 180' of chain is adequate.

However this thread was created to hear from others the anchor chain combo that they are using. In addition to hear of any chain storage issues or alternatives they have dealt with.

I have already determined that I want additional chain as my preference.

Thanks much

You are right Tee Jay, it all depends on where you are going. From New Bern North Carolina to either Baltimore or the southern Bahamas we have seldom used more than the 100' of chain that is on our main anchor. When we did put out some of the 250' of line that follows, it has never been more than the length of our 30' chain snubber. Why carry the weight if you are not going to use it? Chain is expensive, heavy, hard to mark, and needs re-galvanizing every few years.

By the way, is there some way to train the galvanic corrosion gremlins to attack the cheap inch thick zinc hull anodes rather than the expensive microns thick zinc galvanizing on the anchor chain?

We were on the boat last week for a couple weeks of sailing on the North Carolina Sounds before hurricane Irene appeared and we returned from Bath to New Bern to prepare for the storm.

The anchor chain touches the boat's metal in three places. It sags between the anchor roller and the windlass touching the bow fitting. It wraps around the windlass chain wheel. And, it touches the hawse hole in the windlass before dropping into the chain locker. I measured the resistance of all three spots. All were below 1 ohm although the spot at the bow fitting was hit or miss as the chain moved around. The resistance link to link in the chain is also under 1 ohm.

The windlass motor (and hence the windlass body) is connected to the boat DC ground system by a #8 wire that goes to the underwater metal plate mounted forward and to starboard of the keel. All of the underwater metal and the engine are connected to the plate.

I guess the surface area of each link in the chain is 2 square inches. With 12 or so links per foot, there would be 2400 square inches in 100 feet of chain. There is far more underwater area of zinc exposed on the chain of my anchored boat than on the few square inches of zinc anodes. Why wouldn't the chain galvanizing be as subject to galvanic attack as the anodes?

Isn't distance a factor? Those electrons have to travel from the chain to your prop? I assume this is why my bronze seacocks don't have zincs (they are electrically isolated).

Good luck with the storm, hope it jogs east of you.

anchor and rode

Hi there, I bought my dream boat last summer in SW Florida. It came with a 35 lb CQR w 10 feet of stainless chain and what looked like 150' of 5/8 double braid in marginal condition. Also has 35 lb Bruce with another 10' stainless chain and 150' three strand. Moved stainless chain to danforth stern anchor.

I left the Bruce the same but for the CQR I bought a 50' section of 5/16 ht and spliced on 150' 5/8 three strand. This will eventually be my secondary rode but all I could afford for now. It's also all I really need for our deepest anchorages in the SE like the other captain said, in around 25' water.

Also have FX 23 under port settee.

Is this sufficient for northern Bahamas? Maine? Chain is expensive, and I'd love to have at least 150' but $$ is tight and I don't want to buy enough chain for the pacific to rot in the chain locker while I anchor in 10-20' water until retirement.

Also have manual windlass which is not as easy as I thought. Singlehanding this summer I sailed into cape lookout late one night and anchored in a breeze. Somehow I totally blew it and anchored too close to a boat so had to get my gear up and reset. Not easy. I'm a 200 lb farmer, but by no means superman with my blown out disks. Amazing the difference in weighing anchor compared to my old 5 ton boat. I Guess the windage on top of extra weight adds to the load.

Curious about the muir windlass mentioned earlier in thread, I think. Can't reference thread on iPhone. Does it have more mechanical advantage than the stock lewmar?

Hi Folks,

I've been sailing around Maine for the past 20 years or so and lived on a trimeran in St Croix for a few years in the 1970s. I've never felt the need for the length of chain some of you have. I currently have a 33 lb Bruce with 50' 5/16" HT chain and 300' 5/8 nylon rode. My backup is a Danforth 3000 HT with 30' 1/4" HT chain with 180' 1/2" braided line.

On rare occasions I need to anchor in deeper or more exposed locations that I'd like but I've never had a problem holding. I've always assumed that if the chain is sufficient to transfer pull horizontally on the sea floor you are getting all you can expect from your chain. Have some of you had your long chains pull tight and drag?

You should use a snubber if anchoring all chain to provide some elasticity. You are correct about the horizontal pull but there are other reasons that using all chain is nice:
1. easier to stow
2. when in tidal waters and the boat is aligned with the current, a nylon rode can end up getting caught in the rudder/prop, where chain will hang more vertically
3. superior abrasion resistance.

anchor and rode

We have been cruising the east coast from Maine to the Bahamas for the last eight years on our C37.Our everyday anchor is a 44 lb Bruce with 100' of 3/8 BBB and 200' of 5/8 nylon 3 strand.99% of our anchoring is in 20'of water or less meaning that the nylon rarely gets wet unless the wind picksup or a storm threatens.The only anchorages that I can think of that require more than the chain are Block Island and Newport RI.
I also acknowledge anchoring on the west coast requires much more rode having sailed in the Channel Islands of Calif.
When using only chain I always use a nylon snubber to absorb the shock load.
Another very important item of gear on the east coast is a washdown pump and hose as most anchorages are very muddy especially the Chesapeake and mid Atlantic states.
