10. The __ anchor should never be used to anchor boats larger than a small canoe, rowboat, small sailboat or inflatable boat since the holding power is weak. a mushroom-type b plow-style C fluke-style

## Step 1<br />The problem is asking us to identify the type of anchor that is not suitable for larger boats due to its weak holding power. The options provided are a mushroom-type, b plow-style, and c fluke-style.<br /><br />## Step 2<br />We need to consider the characteristics of each type of anchor. A mushroom-type anchor is known for its broad, flat shape, which allows it to grip the bottom of the body of water effectively. This makes it suitable for larger boats.<br /><br />## Step 3<br />On the other hand, a plow-style anchor is designed to dig into the bottom of the water, providing strong holding power. This makes it suitable for larger boats as well.<br /><br />## Step 4<br />Lastly, a fluke-style anchor is designed to grip the bottom of the water, but it is not as effective as the other two types. This makes it less suitable for larger boats.
