12' on Lake Eirie,or Huron for that matter? The first trought would
stick you in the mud and the first wave would bury you in it.

With 18 foot depth, a 12 foot wave would leave 12 feet depth in the trough, and
the crest would have you with 24 ffet of water under you.

Our boat only drew about 6 feet, to the keel. Very possibe; I was there. It
was the roughest I have ever seen the lake, in 10 years of sailing on the lake.

I love sailing in waves of up to 6 feet. That just means there is enough wind
to really boogie! g

Over 60 knots of "breeze" is a bit too much, though.
