Warren-
I have mentioned that I have an all-chain rode on my CD-22 many times.
Actually, it's 100 feet of 1/4" GS40 High Test chain followed by 150 feet of 1/2" three-strand Nylon rope, the rope being for more traditional anchoring situations where more scope is possible.
However, since I usually anchor in a steep-sided inland lake, I can't get the desired 5:1 or more scope ratios recommended for anchoring, so the solution that works is to use an lot of chain and an oversized anchor to hook up as quickly as possible and to minimize the rode length so as to keep the boat off the shore in narrow inlets.
To that end, the 100 foot of chain weighs 74 lbs, and the Fortress FX-16, while only weighing 10 lbs, is size-intended for 33-38 foot boats.
One real positive advantage of the all-chain rode is that the boat "searches" or wanders much less at anchor in the shifting winds as compared to how much it would with a long and light section of rope and a short chain. This is particularly advantageous in those narrow anchorages.
Another advantage is that the windlass gypsy and the chain have ZERO SLIPPAGE as compared with using rope. Essentially, you have a chain and a sprocket, not a friction tooth and rope arrangement.
The chain also brings less water aboard when it is retrieved as compared to a saturated rope.
I originally had some problems passing the larger diameter rope to chain splice with my Quick Aries 500 windlass, but solved the problem by inventing my own splicing technique.
Using 100 feet of chain up front enables me to anchor most all the time without getting down to the rope section.
It's been a great addition to my boat, and helped solve several problems at once, and additionally helps to hold the bow down in chop, necessitating less gas wasting bow down trim with the motor.
This system works for me where I boat, but, as they say, YMMV!
