ANCHORS AND ANCHORING TECHNIQUES
Choosing an anchor for the 2009 season? Anchors come in a variety of types, Fluke, Claw, CQR, and the Fisherman. Each has their own strengths and weaknesses. This week’s newsletter (http://myboatsgear.com/newsletter/200788.asp) looks at each anchor type and their modern equivalents. We also provide some anchor test data and links to reports. This information will help you pick the right anchor and size! RSS feeds are available at http://myboatsgear.com/mbg/index.asp
