With the yacht inverted, preparing it had to have been extremely difficult. Salvage crew would have had to cut the mast off, seal the boat, turn it over and then tow it.
Every day that passes, the chances they'll be found gets exponentially worse.
They are going down to check if the mast is still there.
I doubt the crew had any chance of survival.
I am waiting for reports from people at the yacht.
However, our members are still on standby and if we hear anything we'll act swiftly.
