The stern structureStern frame has two special features not found in other structures: the first is that it is located near the propeller which is a vibration source. The second is that it supports the propeller and rudderRudder. Therefore, the stern must be designed to have sufficient rigidity so as not to allow excessive vibration nor deflection which would disturb smooth rotation of propeller and rudder. In this chapter, important points in the design of stern structure are explained including vibration of stern overhang and bossing, and design of stern frame.

The stern structureStern frame has two special features not found in other structures: the first is that it is located near the propeller which is a vibration source. The second is that it supports the propeller and rudderRudder. Therefore, the stern must be designed to have sufficient rigidity so as not to allow excessive vibration nor deflection which would disturb smooth rotation of propeller and rudder. In this chapter, important points in the design of stern structure are explained including vibration of stern overhang and bossing, and design of stern frame.
