Fluke Danforth Boat Anchor Sizing Chart

Pros: Performs well in mud and sand. Arguably the most popular general purpose anchor. Stows easily on most bow rollers.
Cons:  Does not perform well outside of mud/sand.
Bottoms:  Performs excellent in mud/sand. Performs poorly in other bottoms.

The chart below lists the recommended Fluke/Danforth Anchor Size for various lengths of boats. The anchor sizing chart below assumes average boat characteristics in average anchoring conditions. If you have an exceptionally heavy boat or are anchoring in exceptional conditions (typically greater than Gale force winds) you may consider going up one size of anchor or larger.
