C ommunication onboard is very important. If communication does not go well, there is a big possibility that a lot can go wrong. Think for example of:
As a crewmember on the ship you will use the VHF radio.
To talk on the radio there are 3 rules on how to do it correctly:
Rule 1. Press the send button BEFORE you start talking!
Rule 2. When you talk, do it in a clear and understandable voice.
a. Never talk with the wind in the radio. The receiver will not hear or understand you!
b. Do not mutter in the radio. The receiver will only hear a noisy tone!
Rule 3. Finish talking BEFORE you let go of the send button!
When orders are given by the captain or any other officer, you have to repeat the order. This way the captain or officers hear that you have received the order.
Warning: Communication is a 2 sided process! If 1 side does not co-operate, the chain of communication will be broken, with consequences!

Some values are fixed for the Sirrah. You’ll need them later on in the calculations. They are:
