Re: anchor for 16' 4" boat
You will want to post some more information. How big is the motor, approximate weight of the boat at anchor, where are you boating (river, lake, bay, ocean, bottom composition (big rocks, little rocks, mud, sand), and what type of anchoring you are planning on doing (fishing for a couple of hours, overnight, permanent mooring). All of these factors will determine the type of anchor you will need. Post some more information and you will get some experienced advice!
