Prior to spot lock I used 2 #20 Navy Anchors. The longer the line, the better boat control, plus you can move if you place your anchors correctly. Now that I have spotlock, I still use 1 #20 Navy Anchor when the grandkids swim off teh boat. Anchors are to be set off both ends of the boat on teh upwind side. Plan it so the wind blows the boat to your spot and it will hold it there. Th is method is extremely effective. I have a buddy who Crappie Guides using a 24' pontoon boat. He double anchors all teh time. Holds his toon perfect.
