With your boat, 2 or 3 people, gear. etc, a 35 pound anchor is none too big. I have a couple of anchors, one 30 and one 45, they both live on my trailer, brackets on each rear corner, chain welded on to padlock anchor to trailer, then depending on the drift/water I pick the anchor du jour. Also how much rope do you have, just replaced mine last year and went to 65 feet which is way more than enough. But then remember to watch the angle of the dangle of the rooter unless you are using chain then it's the angle of the bangle.
