How to Draw an Anchor
To draw an anchor, start by drawing a cross with a ring on top. Then, flare out the ends of the vertical part of the cross, and draw a large crescent at the bottom of the cross. Next, draw a triangle on each end of the crescent, and draw a smaller triangle coming off the center. Finally, erase all of the lines inside the main outline of your anchor, and shade in your drawing.
Draw a ring. To draw the ring, draw a circle. Then draw a smaller circle inside the first circle. At the bottom middle of the inner circle, draw a skinny trapezoid. Draw a thick cross underneath the outer circle.  At both ends of the crossbar, flare out the ends. Slightly flare out the bottom half of the vertical part of the cross. The shank is the vertical part of the cross while the stock is its horizontal part. Draw a crescent at the bottom of the cross slightly wider than the crossbar width.  At the crescents midpoint, draw a small triangle pointing downwards. This is the crown. At the end of each arm of the crescent, add a triangle pointing out. This is the fluke. Draw the outline of the anchor based on the sketch.  Erase the guidelines.  Add color.
