Chapman Piloting
John: Recommend you get a copy of "Chapman Piloting, Seamanship and Boat Handling", the 63 edition being written by Elbert Maloney. 856pp., 1999. Probably there is a newer edition as well. This book contains a wealth of information, including quite a bit about mooring. For its size the book is fairly inexpensive, and it is probably available in pulic libraries as well. From my perspective, its what is down at the bottom of the mooring that counts a lot more than the buoy. Dick.
