Obviously, if they have a beacon, we have a position to work from. We have tools, such as a search pattern, whereby we can say that the last known position was there, and that it's been three hours. We look at the weather, sea conditions, and everything, and we establish a drifting pattern. This is how we can search. So, yes, having a position does reduce the search time.
When it's simply somebody calling to say that a fishing vessel should have been back 12 hours ago and isn't, the first step is to confirm that the fishing vessel is not somewhere else, because it could have come into a different port. Once this is confirmed, the search and rescue operation starts.
