Hi Rich, The port sail locker is where I keep my "Claw". I have a narrow milk crate type of box that holds the rode, chain and anchor: always ready for use. My guess is that it should hold very well in 20 kt winds, though I've only used it as a lunch hook. But holding strength is more a function of the type of bottom you are using. If you have a nice sandy bottom, you get excellent holding power. If it is soupy mud, you'll need a Danforth with large area to hold under those conditions. That's why anchoring is an art form for sailors, and why you need different tools (anchors) for different bottoms. Don't hesitate to use two anchors. You sleep much better knowing that two anchors are down and holding, than just using one. Two anchors also restrict the boat's desire to "sail" around the anchor. With one anchor, your boat might fall off and sheer away in one direction until the anchor rode jerks the bow to a stop. The stern then swings around, the bow falls off in the other direction and the dance starts all over again. Two anchors down, and that dance is cut to almost nothing. Connie
