b.) they never weather a storm at anchor.

most recreational boaters don't either.... and if they did, hopefully
they would have sense enough to put a snubber on each anchor line.

a "storm" strong enough to jerk and all chain rode loose from the bottom on a
for an anchored recreational sailboat is not even 20 knots of wind and 3 foot
waves.

but thanks for enlightening us, for you have told us *you* are always tied to
the dock at the end of the day, so you buy 300# of chain just so you can brag
about buying 300# of chain to weight down the bow of you boat.
