APPENDIX 3 HOW TO INSTALL THE RETRACTION TANK FOR WOODEN VESSEL
AP-9
•
Install a flow rectification component to the hull where the transducer projects.
Install a fairing or stainless plate as the flow rectification component. See the next page to select
a faring or stainless plate.
Selection of the flow rectification component
According to the vertical distance between the
bottom line of the keel and center of the retrac-
tion tank, select a fairing or stainless plate as
the flow rectification.
Recommended dimensions for the stainless plate
• Length (bow-stern direction): R. P + 20 mm or more
• Length (both sides direction): Pipe O.D + 100 mm or more
• Thickness (T): 10 mm or more
• Diameter of the hole: Pipe I.D + 1 mm
Note:
For flat bottom hull, prepare a wooden reinforcement block to decrease the vibration of the
retraction tank. The recommended dimensions of the reinforcement block are shown below.
Recommended dimensions for the reinforcement block
• Height: 300 mm or more
• Length (bow-stern direction): Same as the distance between the ribs
• Length (both sides direction): Pipe O.D + 100 mm or more
• Diameter of the hole: Pipe O.D + 1 mm
