How heavy of an anchor do I need for my boat?

Holding power is formulated based on environmental factors, like wind speed. As a general rule, a holding power of 90 pounds is sufficient for safely anchoring a 20′ boat in winds up to 20 mph. For the same wind speed a holding power of 125 pounds is adequate for a 25′ boat.

Do you drop anchor in a storm?
