Re: whats the best way to anchor a boat.
Boy is that a loaded question.
How to safely anchor your boat depends on the size of the boat, the type of anchor being used, conditions at the time (wind and current), water depth, bottom type (gravel, mud, weeds, rocks).
Generally, I prefer to anchor with my bow into the wind, and leave as much line out as needed to prevent the anchor from lifting off the bottom, sometimes this is a considerable amount.
I also let out my stern anchor straight off the back, again leaving as much line out as needed to prevent drifting.
I use 25# anchors, that are blade type, they dig in decently and weigh enough to hold my boat easily in most any condition.
If it is soo bad that my anchors wont hold, I don't stay on the water.
