1.1.5 Installing stays (anti-vibration measure)
Install stays from the top of the hull unit to the ship's hull. The stays should be angle iron
with a size of 75×75×9 mm or more and at least two pieces should be used; one each to
ship's bow and stern directions. Install if possible, two more stays in ship's transverse
direction. This measure must be done to prevent damage to the transducer.
Do not install the stays on a crossbeam on an overhead. Vibration-resistance effect is
reduced since vibration is applied to the stays as rotation force. Install them horizontally.
