What type of anchor is best to use in rocky bottoms?

The best type of anchor to use in rocky bottoms is the plow anchor. This design features a sharp, plow-shaped tip that penetrates into the seabed and has a large, flat section that holds well once dug in. The shape allows it to create a firm grip in uneven and rocky surfaces, making it effective in providing stability against wind and tide.

Other types of anchors have different characteristics that make them better suited for specific conditions. For instance, a fluke anchor is designed for soft bottoms like mud or sand and might not hold well in rocky terrain. A grapnel anchor, while useful in grappling rocky surfaces, generally lacks the holding power and stability required for sustained anchoring. Finally, a mushroom anchor is typically more effective in soft, muddy areas where it can settle and create a suction effect, and it wouldn’t provide secure anchorage in a rocky environment. Thus, for rocky bottoms, the plow anchor is the optimal choice due to its design suited for penetrating and securing in such conditions.
