Well done! You can copy and paste. Go to the top of the class … except you neglected to read down the rule book a line or two below and so left out the ONLY means specified for determining a risk of collision. Let me know when you find it.
Just a reminder, navies train for war all the time and transmitting on radar, AIS, VHF, sonar, echo sounders and other means can at times tell the enemy not only that we are there, but positions, courses and speeds, the type of ships, force composition, and other things whilst detracting from our ability to passively detect the enemy doing any of those things.
