Just saw this on West Marine:
Anchor Type
Size
Holding Power
Helix
10" screw
10,000lb.
Dor-Mor
650lb.
6,500lb.
Mushroom
500lb.
1,200lb.
Concrete
2,000lb.
800lb.
Concrete
8,000lb.
4,000lb.
I don't understand the difference between the two concrete but clearly 500 pounds without slack and/or snubbers isn't going to do it.
I think we're going to start with adding slack & snubbers before the added expense of more weight and chain.
