Setting the stern anchor.

[jrc]

Never tried a mushroom anchor, I'm just parroting what I read. I'm glad it works for you.

As to boat wakes swamping stern anchored boats. I use a stern anchor to keep my stern is facing shore and the bow pointed out. In most cases, it's impossible for significant wake, wind or waves to come from the shore.

Away from shore, stern anchoring may be a higher risk. But although, a bow anchored boat will usually point into the wind and the wind driven waves, that's not always the direction of the boat wakes.

In a steady wind my boat likes to tack when on a single bow anchor. It will turn the port side to the wind, and the swing around and turn the starboard side to the wind. It will keep swinging back and forth. A stern anchor usually slows or stops the tack.

Here's a neat gizmo for dropping a stern anchor: It's an anchor line that stretches—a whole lot!
