Which two common anchor types are described, and what are their typical uses?

• A. Grapnel anchor – best in rocky bottoms.
• B. Stockless anchor – general purpose; Danforth anchor – effective in soft bottoms.
• C. Plug anchor – decorative purposes.
• D. Danforth anchor – effective in soft bottoms.

Answer: (A)

The main idea here is matching anchor design to the type of seabed where you’re anchored. The grapnel anchor is built with multiple short, curved prongs (tines) that grab onto rocks, reefs, or clutter on the bottom. That grabbing action makes it especially effective in rocky or weed-covered bottoms, where digging anchors would have trouble or could get fouled. It provides reliable holding power by catching on irregularities rather than trying to dig down, and it’s typically favored for smaller boats or temporary holds in rocky areas. In contrast, anchors designed to dig into soft bottoms (like mud or sand) work differently, which is why a description saying another anchor type is best for soft bottoms doesn’t describe the grapnel’s suitability. The other options mix real anchors with uses that don’t align with the grapnel’s purpose, such as decorative plugs or general-purpose anchors, so the statement that the grapnel is best in rocky bottoms most accurately captures its specialized use.
