A cable grip is designed to take the load on cable.

Do you really mean "cable," as in wire rope? That would be VERY unusual as an anchor rode.

I think we have a winner,
Quote:
The LMG is a device for pulling, gripping and tensioning unsheathed wire ropes, cables, and metal rods in all forms. The parallel jaws provide a firm, non-slip grip without causing damage to the wire. A special spring-loaded guide prevents the grip from dropping off the wire and affords instand release without jamming.

WESTERLY has a winch, 40' of 5/16" HT chain, and 300' of 1/4" stainless steel cable.

It's what the boat came with when I bought it 20 years ago.

I have found the winch to be very serviceable, and the rode works well, although it is more like a line/chain combo in the swinging area needed. It has a pawl that keeps the drum from moving, if the winch were to fail holding the rode, the bow would probably be gone along with the winch.

In my towing days, we had a carpenter's clamp for emergency purposes (tow machine brake band failure, etc) that clamped around the wire rope. But I've seen one of these explode when exposed to dynamic pressure. We had special precautions to keep the crew safe when one of these was in service.

The best answer for increasing the ability of the rode to safely weather high strains, is to increase scope. As FF mentioned, a kellet can be helpful, as long as the winch is strong enough to handle retreival. If you are rigged appropriately, kellets can be retrieved separately.

WESTERLY's solution for extreme weather conditions is to replace the SS cable rode with a 3/4" nylon line (435') that is available at the winch. Just takes a minute or two to change out the shackles, this almost doubles the available safe working load of the assembly, and provides much needed dynamic surge capacity. When deployed, it is still made fast to the winch. Done this twice in the last 20 years, may have been un-needed both times.

Interestingly, I've seen broken strands on the wear areas of my SS anchor cable, but only when I used 316 SS. This last time, I purchased 304 SS and over 3 years have yet to see any broken strands. SWL is almost identical, but service life is 2-3 times that of 316 SS.

Almost all of the cable reel windlasses I have seen are on fish boats that are fully manned.

This means weather anchored for an hour or a day , a watch was able to observe the vessel.

Perhaps the wire could be removed and nylon used , to gain the stretch ability that makes nylon such a delight.

If I designed this winch, it would have a spring loaded drum. So, at some preset torque, it would turn a little, then return back.
Hard fastened steel all the way to the seafloor is not for yachts, I submit.

My two centavos worth ---

Jay N has drum setups figured out, has for a very long time it would seem. The Nordlund in question (call Nordlund if an OEM install) likely has a pretty robust cable drum system but knowing how robustly it is affixed to the deck structure is a question for us in the dark. Thus one of the many commercial cable grippers can be considered. Just keep it clean and oiled as salt water will destroy it in short order.

Thousands of drum setups like it in use worldwide. Stainless rode cable is a dream for the commercial guys due to cost. As Simi notes, strength less than non SS cable but an extra 1/16" makes up for it. And no rust!

FF, deck watch overnight on a lightly or single manned (peopled if in Canada) fishing boat not common. Those that I'm familiar with just drop the hook, affix the drum holder and go to sleep. I doubt they know an anchor dragging video can be found on TF.

As mentioned, cable drums normally have a cog or other braking device. The OP states he needs to determine how to set and release this braking device with less effort. A visit to the commercial dock will yield results, at worst share a cup of coffee or beer with a fish boat guy who knows the ropes!

Humm, some big yacht owners do just fine with all steel, especially those with metal boats.

fine, as long as you anchor in mud, sand, and the like. Once you hook into some of the more unstoppable objects/materials is where it gets more interesting and costly.

Much more room for road with a mix of chain and cable on the drum. Stainless because i didn't buy it, nice though

I'll try the "knot" with nylon on inch line and let you all know if it works, i.e. Doesn't slip

Thanks,
