Re: Breasting my fin keel? Help please.
I have no experience with tides being on the great lakes but we do get water level variations of several feet due to wind. You said the bottom under you is hard. The one caution I'd give is that in our case, as the keel is starting to touch the bottom small waves can lift and drop the boat and it can hit pretty hard. Once it's firmly seated it's fine, but as water is going out and coming back it can pound.
