Larger always has more holding power, but be sure to check any critical dimensions if you have a bow roller, windlass, etc.

Mine was within less than 1 inch of being too large.

I don't remember if I made the mistake of ordering the largest they suggested in my boat's size range or if I simply clicked on the wrong size when ordering.

The anchor I have (45 lb) would probably hold well in a storm on the ocean. Since we can't overnight on the lake, I don't need to worry about an anchor holding if a storm creeps up on me while I'm sound asleep.
