Anchor Size

[nipper]

Thanks BC. To the depth of the water you need to add the height of where the rode will be fastened to the boat from the water. It's not much, but that 4 or 5 feet should be factored into the equation. 7:1 is proper, and probably necessary for overnight anchoring. You can generally get away with less when you are in the boat and attentive to what is going on (i.e. whether you are drifting despite having the anchor down). I am always amazed when you see folks anchored (often with other boats rafting beside) with the anchor rode going virtually straight down.
