As the officer-in-charge of operating GMDSS equipment, my first action would be to immediately activate the distress alert on VHF channel 16 and make a DSC distress call. This will alert any nearby vessels and the VTS of our emergency situation.
The distress message should contain the following information:
Who we are (vessel name and call sign)
What has happened (steering failure)
Our position (latitude and longitude)
Our intentions (drifting or anchoring)
The number of people on board
Any other relevant information, such as the extent of the damage or if there is danger of collision
Example of a distress message via radiotelephony:
"Mayday, Mayday, Mayday. This is [vessel name], [vessel name], [vessel name]. We have suffered steering failure and are unable to maneuver. Our position is [latitude and longitude]. We are drifting towards [direction or landmark]. We have [number of people on board]. Requesting immediate assistance. Over."
After sending the distress message, I will continuously monitor VHF channel 16 for any response and maintain a listening watch on VHF channel 13, which is the designated navigational safety channel in the VTS area, to keep track of any nearby vessels and their movements. I will also make regular updates to the VTS and other vessels in the vicinity about our situation and intentions.
