I am very new to sailing, but live on the water off of the Chesapeake. It is an estuary that is generally shallow and 4 feet deep (high tide) at the end of the dock. With the exception of a catamaran, is there is sailboat that can be used in such depths (lack thereof)? The Bush is subject to winds which at times can even leave the end of the dock just mud, no water. Is there any solution? Thanks for your help!
