Several people have asked me about my ground tackle setup, so I thought that I would post this here to explain what it is, and how I use it.
Below is a diagram of how I would deploy the anchor if I needed the greatest holding power (storm).
The optional 10' of 1/2" chain weighs about 34lbs, and acts like a kellet, except that it will not chafe the nylon anchor rode. To be honest, I have not had the need to use it in the 3 years that I have hade the boat, and am afraid of having to haul it up with the two arm windlass. The windlass is getting old and creaky...
The usual setup is to deploy the 33lb Rocna on 25' of 5/16" HT chain.
You'll notice that the retrieval line is tied, with a float to the thimble at the end of the 5/8" nylon rode. The float keeps the lightweight line from getting tangled on the bottom, and should the nylon line ever be cut, it would make retrieval easier. I believe that I have a better chance of catching this with a grappling hook. Because I don't usually anchor in more than 30' of water, if I untie the line from the thimble, it would act as an anchor marker.
I tried the anchor a couple of times without the retrieval line. I found that it was hard to break free, and it hauled up about 15 lbs of bottom. Now that I use the retrieval line, the anchor breaks free MUCH easier, and it only brings up about 5lb of muck.
Ya' it's a Chinese made Rocna; but it works fine, fits my bow roller, and sets right every time.
Here are two pictures showing how it fits on the bow;
I use the retrieval line as a safety, in addition to a stainless steel carabiner hooked to the Rocna's rollbar, to keep the anchor secure on the bow roller.
I'm putting this here for my benefit, but if it helps someone else, you're welcome.
