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 x 75 x 9 mm or more and at least two pieces should be used; one each to ship’s bow
and stern directions. If possible, install two more stays in ship’s transverse direction.

Figure 3-7 How to install stays
Do not install the stays vertically as shown below. Vibration-resistance effect is reduced since
vibration is applied to the stays as rotation force. Install them horizontally.
