Obviously, you don't sail the Chesapeake. We spend most of our time in

often raft up with others, so knowing the actual depth is even handier.

Actually, waters that are very similar to C/B, mostly the western 1/3
of Lake Erie; however, Detroit and St Clair Rivers as well as Lake St
Clair can make things very interesting on your way to Lake Huron.

You learn to stay at least a mile off shore, and then head straight in
when it is time to go to port.

The shore line is definitely not your friend.

If you don't touch bottom at least once over the weekend, , you stayed
in your slipG.
