Divers lost+recovered alive off Kimmeridge Monday

Was anyone listening to this on the VHF at all? I could only hear the coastguard's half of it.

It sounded like the dive boat in question searched for an hour before calling mayday. Am I right? That sounds rather bad practice to me.

I would have gone to help search (was only 15 mins away) but didn't have enough fuel left.

Why was that bad practice, were they in grave and imminent danger, or grave or imminent danger

I think what nos is saying is, an hour looking for a missing diver before calling the mayday was bad practice.

As a diver myself, the practise is to plan a dive and then dive the plan, so the skipper of a boat will/should know the dive plan with regards to maximum dive time. If that time passes by more than 5 mins and no surface marker bouy has been sent up or seen, then that diver still down should be considered in grave and/or imminent danger. So appropriate actions should be taken, including increasing search perimeters by getting help from divers on boat for possible(only if appropriate) underwater search patterns, and making pan-pan or more likely a mayday to get additional help for searching further afield.

If that is the case then the only right course of action is a MAYDY.
IMHO

the MCGA press release says the divers had been in the water for an hour when the maday went out rather than "missing for an hour". I'm not a diver myself but I guess that they would not have been missing that long then?

From what I heard on the VHF the divers were diving with an SMB rather than a DSMB. They were 1 hour 15 minutes overdue-or the boat lost contact with them for over an hour and spent time searching downtide for them before the mayday was called.

I DID only hear the Solent coastguard/Portland coastguard side though-apparently even the coastguard was having trouble hearing the dive boat itself and repeated everything at least twice.

It actually sounded like the skipper wasn't very competent-it took nearly 5 minutes for the coastguard to work out how long the divers had been out of contact.

<edit> The divers had been in the water for well over an hour before they were recovered- the boat that found them did so nearly 30 minutes after the mayday was called.

If they were diving towing an SMB rather than just surfacing with a DSMB how did the surface cover lose them in the first place?

Losing divers

Re.If they were diving towing an SMB rather than just surfacing with a DSMB how did the surface cover lose them in the first place?

There are plenty of scenarios....

One possibility was they were diving on a wreck/reef as part of a larger group of buddy pairs. If this decided to/ were forced to drift off the wreck and the rest 'dug in' to the wreck, then the skipper would have the problem of following both the moving SMB of the pair that are being carried away with the current...and those that remained stationary where they were dropped.

Even on drift dives...where all the buddy pairs go in together with SMB's and allow themselves to be carried by the current...I've seen some pairs head off in totally the wrong direction due to a mix up with their navigation giving exactly the same seperation of buddy pairs.

As a previous poster said 'plan the dive, dive the plan'...and be competent to follow that plan (e.g. being able to use a compass correctly on a dive). Obviously things can and do sometimes not go to plan through no fault of the divers or the skipper.

From what I've read of this incident, one thing seems pretty clear in that skipper should have raised the alarm a lot earlier.
