Am I reading you correctly? You say that the boat hit the bottom and broke because it was not deep enough where this happened?
I was out at Upper Captiva on Saturday, strong breeze, and 2 to 3 foot occasional swell with 1 to 2 wind driven on top. Crusier wakes much bigger. Came back behind Captiva to anchor, stayed there until 5:00 pm, wind had dropped by that time. But it wasn't "Flat" as some would say, where I was. Condolences to the family.
