I don’t know many details on the loss there so I do not know if they were able to be saved or if they would have been assumed dead before the coast guard could have responded. Maybe the coast guard there just doesn’t care?
Can’t really compare either of these situation because they differ too much. Ask the Greek coast guard why they didn’t make an effort.
Apparently it covers their ass since they would only be held liable if they misrepresented the dangers. Since they mention death 3 times on the first page, I don’t think they did.
