Interactions with other boaters
This is probably the top thing that I would consider when anchoring. Key questions include:
- Am I allowed to anchor here?
- If I am using a single anchor, and the winds or currents change where will my boat swing?
- Are other boats using a single anchor or multiple? You should do the same thing, so that your craft moves constantly with other crafts.
How many anchors?
I would recommend a single anchor. This allows you to:
- Avoid tangling multiple anchors
- Dedicate the proper amount of rope or chain to the single anchor. This will be much more productive that multiple anchors with insufficient scope.
- Be much easier to manage
- Be clearer for your fellow boaters where your anchor lines are running.
The only times I would consider using multiple anchors is when:
- The wind, waves or current are running in different directions and you have a very good reason to point into one of them.
- Boats around you are using 2+ anchors and you need to as well to avoid swinging into one another.
I have personally had good experiences with both personally Bruce Claw Anchors and Danforth anchors. More info.
The Claw works great in mud and sand, although on harder surfaces, I sometimes had trouble getting it to grab.
How much scope?
How much rope or chain do I need?
Typically, if you are using chain, you need to use 3 feet of chain for every foot of depth. In your case this would mean 30 feet, if the water is 10 feet deep, and 60 feet, if the water is 20 feet deep.
If you are using rope, you need to us a 7 to 1 ratio.
The key is that you don't want to pull up on the anchor, you want to pull it a long the bottom.
Setting your anchor
- Drop it in the water where you want it to catch.
- Slowly backup your boat, spooling out line/chain. Don't drop lots of rope or chain at once, because you risk tangling it
- When you have reached a reasonable scope, stop letting out rope/chain and use your engine to reverse on your anchor. Your anchor should be as strong as your engine.
