Re: Anchor
Generally speaking, a Danforth type fluke anchor is a good all-around choice. If anchoring to fish or picnic, a 4 pound fluke "lunch hook" with 3/8 inch nylon line will be sufficient--but just sufficient, assuming gentle current. Longer or more secure anchoring would call for an 8-10 pound danforth type. 3/8 line is still ok but 1/2 would give an extra margin of safety --more expensive to buy, and more difficult to handle. Not really necessary on a small boat like that for an afternoon. With either anchor a minimum of 6 feet of chain at the anchor to absorb bottom chafe and to help set the flukes is necessary. Use a thimble to absorb strain and splice the rope around it to the chain. For an anchor, don't consider anything else but nylon line. Poly is cheaper, but does not have the strength, UV resistance, or longevity. Does not hold knots as well either. Carry 7-10 times (in length) the depth of the water you intend to anchor in plus the height to the cleat. Example: anchor in 2 feet of water, with the boat cleat 2 feet above the water is 4 X 7 +28 feet of line and chain. Carry a minimum of 50-100 feet though.
Of course, if you will primarily anchor in a specific type of bottom then buy the anchor designed for that type bottom. The retailer should know which is best for your area.
