Im wondering what kind of anchors to use on my 20ft pontoon. I use 15lb stockless in the front and back but still get pushed around by the wind or a current. Maybe I just need heavier anchors? how big are the typical anchors on a bass boat?
thanks

We always had to use 2 20-25 lbers on my dads pontoon if there was very much wind. We also made sure to give plenty of rope out...

Box anchors

Two 17# box anchors hold my 24 ft in pretty rough water

Box and "Digger" brand anchors--
You get away with a lighter weight with the digger brand but in both cases longer rope helps set the anchor.

Steve, I have never used a box anchor but have been considering it. Can you let less line out when using them?

THiS ^^

I used a 10lb for the rear, and a digger for the front and never had an issue, it's all about length of rope

On your boat yes Mudshark, on a toon less that you need to with a digger, but the longer line creates a better angle to grab.
A length of chain helps on the box anchor also.

maybe my main problem was not letting enough rope out.

When figuring rope for an anchor, 30 ft of water depth will take at least 90 ft of rope

It also depends on where you fish. A hard clay bottom like Lewisville has is hard to get anything to grab.

+1 on the chain and more rope.

How much chain do you guys recomend for the box anchor? And if you had to choose one which would it be? The box anchor or the digger?

I don't use chain on box anchors

I have both on my boat, both work very good but when you total things up the box wins.
One big difference to me is the weight, my box is about 8 pounds heavier.
