Lightweight-type anchor, such as a Danforth, holds well in sand, hard mud, or soft clay bottoms, but is difficult to set in grass or rocky bottoms.


Setting an Anchor 1 After checking area, approach anchoring spot slowly, heading into wind or current, whichever has a stronger effect on boat.


2 Stop boat and lower anchor over bow − do not throw it. The end of rode should be attached to boat before releasing anchor.


Bruce anchor holds well in most types of bottoms.


3 Let out anchor line as boat drifts downwind. If wind has too little effect, back boat very slowly while letting line run out freely. Avoid backing too fast, which could cause anchor to bounce along the bottom.

Plow-type anchor holds well in most types of bottoms.


4 When a scope of 5:1 has been let out, wrap line around bow cleat and reverse slowly against it until it becomes taut. Once anchor is set, let out additional line as needed. To check whether anchor has set, hold a hand on the line while reversing to feel for any chatter or vibration from anchor dragging or bouncing along bottom.

Horizontal or low-angle pull digs in anchor.


Mushroom anchor is best for mud and silt bottoms. Unlike other anchors shown here, it depends primarily on its weight for holding.


Most anchors dig into the bottom and hold best when pulled at a low angle to the bottom. A more vertical angle of pull can prevent the flukes from burying or even break the anchor free.
