TWIN SCREW TUTOR
The Simple Manual for Maneuvering Twin Screw Vessels

ABOUT THE AUTHOR
Captain Charles J Riechert

Captain Reichert has logged over 100,000 nautical miles operating twin screw vessels. During that time he trained personnel to maneuver and safely operate commercial U.S. Coast Guard inspected and certified passenger vessels that had twin screws and twin rudders.It became obvious to him that the students did not understand what forces were being exerted beneath the vessel when a maneuver was being executed. It seemed that no matter how comprehensive the explanation, it had little or no meaning to the person involved. Captain Reichert drew a crude set of visual aids in the form of flash cards and sent them home with the students overnight. The rate of improvement in every student was noticeable and the students soon were maneuvering the vessel with much more accuracy and understanding.

Several years and much thought later Captain Riechert decided to improve upn his method and to offer it in the form of a FLASHBOOK for sale to the public. The simple yet understandable form is a TUTOR for the beginner or the professional who constantly strives to hone his or her skills. The illustrations in the learning manual are plain and give the impression of looking down through a glass-bottomed boat. The water flow and rudder position have a major influence in the maneuvering of the vessel. The explanations are simple and easy to understand. The FLASHBOOK is easily used by one or two individuals at a time and can vastly accelerate learning time.

The illustrations in this book show propellers and rudders, however the same basic forces apply to inboard/outboard drives and many of the maneuvers depicted herein can be successfully accomplished even though rudders are not present. The turning of the inboard/outboard drives causes water flow direction to change and in some cases the response is faster than with rudders. All the maneuvers in this manual require practice and experimenting with your own individual vessel. Always practice in an uncongested area and never put other boaters in danger. Many times you may be able to practice at a deserted dock or float.
