I have a 13 1/2 foot Boston Whaler. It currently has an electric anchor system, with the anchor coming down off the right front of the boat. It is a donut type anchor. It didn't take long last year to realize that one anchor would not hold me in position. Do you advise putting a second anchor off the back? If so, should it also be on the right side of the back or left side? I Don't want another electric system. I also feel that a different type anchor might be better, at least at one end of the boat. What type would you recommend. Most of my fishing is on lakes with varied bottoms. Sorry that was so long winded, but wanted to be as clear as possible. Thanx! A Bunch.
