Rescuers are again pleading to help them help you. If you lose any piece of marine equipment - a life jacket, a kayak, a dinghy, a lifeboard or your Dan Buoy, please let the authorities know to avoid unnecessary searching. When abandoned equipment, whether floating or washed up on the shore, is found rescuers must assume the worst and begin a search.
For example Portland volunteer rescuers report that on 21st and 22nd July two separate tenders were lost by vessels who knew that they were missing, but simply did not bother to report it.
In the second incident, Portland Coastguard fairly quickly worked out what had happened but the yacht in question rebuffed all attempts by another vessel to explain why he should contact the Coastguard to confirm that it was his.
If it - or any other piece of gear - is lost overboard, please let your local rescue authority know - .. .
This was in the middle of an extended search for a missing diver and several other incidents and involved the launch of two lifeboats.
Ros Evans, Portland Watch Manager, says: 'Whenever lost equipment is found at sea, unless we have information to the contrary, we have to assume the worst and begin an investigation which might lead to us starting a search and rescue operation involving coastguard teams, lifeboats, helicopters and other vessels.
'Obviously, there is a significant cost to this type of operation, but we are also very concerned that we may be diluting resources that are needed for a real emergency. Those who report lost or missing equipment to us help us to prevent needless searches. And of course we may be able to reunite members of the public with their lost equipment.'
