Da(m)nforth anchor!

By that title one probably suspects I dragged a Danforth all over the bay in yesterdays storm in Puget Sound. Well I don't know for sure who all was hit but I was. I was anchored in Indian Cove on Shaw Is. We got there on Saturday afternoon and weather was quite nice. Dropped the 35 pound or so Danforth with all chain rode and let out about 60 feet in 20 ft of water. Next morning got up to the soft slap of wavelets against the hull which seemed to grow over time. A couple hours later it was a stiff 15-20 and later still gusting 30-35 with attendant chop that grew to 3-4 feet in height. I was the only powerboat in the cove with 5 or 6 sailboats of varying size including the well known MARTHA, a fairly good size wood schooner, and they all bailed out early. So after lunch my boy and I decided this sucked and said lets move inshore into the more protected part of the bay. Long story short, didn't start but eventually got going and went to pull the anchor. I worked for about a half hour getting that sucker up! I rode over it, I jumped up and down on the tight chain, I tried to back into the wind to get behind it, I finally let out a lot of chain and pulled on that sucker in reverse sideways after exhausting myself and all other means I could think of. My poor Lofrans was getting hot and working its arse off tying to get that anchor up. It finally broke free and we got it aboard. I should have had half again that much scope out for the conditions and did let out some when the wind started picking up, but holy cow that anchor held on short scope! Of course the two flukes are no longer on the same plane, one is now north of the other. I haven't closely examined it yet but it may be OK. We left there and went over to Friday Harbor to wait it out and came home today. I guess Rosario was bad enough the Victoria Clipper wouldn't cross it during the blow. Seemed more like October yesterday!

Danforth will be pleased!
We used the Victoria Clipper in May, from Seattle. There was lots of vomiting, fortunately not from us, in "lumpy" conditions, Cats at speed have odd motion.

"60 feet in 20 depth " amazing holding with such short scope.

A small buoy with 3/8 line to the crown would locate your anchor for other boaters and probably have made retrieval a yawn.

I find the S-Sarca trip slot comes in really handy when I get a very buried and grippy set. Takes a lot of the pain out of the situation.

I've seen (not used) this method of rigging to increase ease of retrieval in tough situations.
It eliminates the need for a separate trip line to be attached / disconnected / stored etc...which one will probably not do EVERY time you anchor and Murphy says you probably won't rig it when you will need it.

Wonder if the zip tie breaks when the anchor pivots during a tidal current change.

I agree Ted,
With that method one is putting the unknown strength of a tie-wrap in the lineup of all the other elements of anchoring that are carefully choosen.
Most of the little charter fish boats in SE Alaska do that but they don't anchor overnight w that arrangement.
It appears clever but is not overnight.

You should only use that break away configuration when anchoring for a short time in an area with a high likelyhood of fouling. Like fishing in a rocky area.

You can use Monel rigging wire instead of zip ties if you want a bit more secure connection that you can still break away.

78PT,
Why did'nt you get vertically above the anchor and "Soak" it up. You would need constant power on to stay vertically above the anchor and I assume that was'nt practical in the strong wind.

What kind of "Danforth" was it? A cheap copy w a steel plate cutout shank or a forged shank and maybe forged flukes as well. From the sound of it you put a lot pull on sideways and should have had a bent shank .. but you only mentioned skewed flukes.

Good short scope performance w Danforths been my experience too. We hung all night in 35 knot winds on a forged shank 13lb Dan. That night all signs suggested benign weather but we were in a blow hole. The name "Windfall Harbor" should have alerted my suspicions .. hmm?
I would have been very comfortable at 4-1 scope in those conditions. But 3-1 is'nt very short scope after Steve's setting vids. I've always been good w 3-1 but most here still think it as "short scope". Some anchors are better at it than others and Danforth is one of those anchors ... IMO.

I might try what was suggested awhile back.

Instead of the wire tie setup that could possibly be an issue....someone suggested tying a length of line, just longer than the water depth to the crown of the anchor and up along the anchor line.

When retrieving the anchor, you just pull this line in separately and if the anchor snags, you now have a trip line already attached that wasn't a hazard to anyone in the anchorage or a danger to your running gear that some always point out.

If weaker than you rode, if it snags and the anchor is free, you can break it. But it should be strong enough to back out a fouled anchor.

Not totally sold but sounds promising.

Here is a vid of the conditions that day.
I did have a hook line on the chain to take the strain off the winch and it too held together. First time I have used such a thing but my other boats didn't have all chain rode.

Eric, I tried everything I could think of with what I had. I was right on top of that puppy, bouncing up and down on in the waves, jumping on the chain trying to get it to pop, but until I let out a lot of chain and pulled sideways on it, NADA. I will post a pic of the anchor later.

I have a Danforth S-40# and boy does it hook well in this mud we have around here. We've had some pretty nice days at anchor with only about 15 mph winds and it took being very careful pulling up a couple of times as the bowsprit was flexxing a bit. Just had to sit over it slowly pulling with the windlass until the suction broke. Lots of mud comes up with it. I've been considering using my smaller 22# Danforth for most anchoring unless I'm spending the night or expect some weather.

Sweed I have a 22lb Dan w forged shank and forged flukes. The flukes and shank are considerably longer than all the "lesser" Danforths. Haven't used it yet but Steve w Panope tested one that I think is the same. It did quite well as I recall.

If the Dans are'nt up to their frequent mischief or getting plunked down in bad ass seaweed or (mermaid forbid) ell grass they are wonderful. And if one dos'nt set them too deep they probably do veering and reversals well too.

Sweed I'm quite sure you're 22lb Dan would be good for anything up to say 35 knots. Not the cheap Dans though. But they may be good for 25 knots but probably not veering much.

Here is the anchor in question. It weighs 40 lbs., the shank is 1"x1.5". You can see its pretty stout.

I like the idea. Makes deploying an all chain road a little more complex. One twist of the chain and it becomes useless wrapped around the chain.

Has me a little worried to...but maybe just steady tension will resolve the twist as it passes the roller before the wildcat.

First attempt might be not much more than twine and in a wide open anchorage.....just in case a knife is needed.

Those Danforths bring up too much mud and pinch my fingers. Weren't they developed for using from landing craft on sandy beaches? Ds are too much for heavy mud. Claws work better for me in such circumstances. ... Hey! Saw a Rocna at Vallejo's K dock last Sunday!

Just picked up a near new Danforth Hi Tensile H20 anchor at Marine Supply in Anacortes for about half the new price. Said to be good for a 50' boat in 20 knot winds with rope and chain rode. Should be a good fit for this boat.
