Here's my opinion and worth everything you paid for it.
I've got three anchors on my boat. I've got a claw on the bow with 50 feet of chain and 250 of nylon rode as my primary anchor. In the cockpit locker, I've got a quikset loose with a bit of rope up to the top of the locker so I can get it out. That anchor's rode is 30 feet of chain and 150 feet of rope rode. It is usually attached to an 11 pound claw (lunch/stern) anchor.
All along the Gulf coast, I have never drug at anchor even in winds up to 50 knots. (Thunderstorm Squall) But we are talking about sand and mud, other bottom materials will probably cause difficulties for my anchors.
My claw on my previous boat (21') proved itself several times. The scariest time was at Chocolate Bay on the end of West Galveston Bay. We had anchored for the night behind an island just off the ICW so that the tugs wouldn't wake us up every 15 minutes or so. There was a huge storm to the north of us and we watched the light show for a while before going to sleep. About 1 AM, I woke up because the wind had died down. Went up on deck and noticed the storm was still raging pretty hard to the north. Just for peace of mind, I raised the anchor and let the light wind blow us about 200 feet closer towards the storm. Dropped the anchor and laid back down to sleep. About an hour later, the storm backed down on us hard!! And instead of being sheltered behind the island, we were now being pushed towards a lee shore. After watching the range markers on the channel for a while, I figured we were not dragging and laid down again. But the pitching up and down in that little boat was not conducive to sleeping. By morning, the storm had blown out and we were still a ways from the shore. Raising the anchor was tough, though, and involved using the genoa winch and watching the bow go down until the buoyancy of the boat broke the anchor loose.
On Impetuous, I've got a hook and line laying in one of the forward dorades so I can hook the anchor chain and run the line to a winch on the mast to get a stubborn anchor up. I've looked at a windlass but I'm not sure I want to put an electrical part and big hole on the bow of my boat.
