Well- that will help me as well!!Thanks to both of ya!The correct way to set your anchors is to drop one anchor, usually the front. Then back the boat away from it as you feed the anchor line out. The amount of line that should be fed out on an anchor is generally 5 times the depth of the water. So anchoring on both ends you should almost double that. Feed out the line and then drop the rear anchor. Pull the front anchor in as the rear rope goes out until the boat is centered between the anchors. Pulling the anchors a little when they are at this angle will cause them to dig into the mud and strengthen their hold. This is the best way to hold your boat steady. Not perfect but about as good as you can do.
The mushroom anchor is not the best anchor to use but is not too expensive and easier to store that many.
hope this helps.
