Yes, that rib was not the most appropriated but that was what they had available.
Portugal is in a deep of very difficult economic problems that are being addressed but that involve huge cuts to everybody, mostly in what regards state costs. With those costs the life guard service has not money to be run as before and they only pay their workers from 9h till 17.30h. They do what they have to do at any our without being paid. The cuts also involved the impossibility to assure what they consider a proper service so the navy is helping with the equipment they have and they don't have adequate equipment for rescue.
That RIB, the one that capsized was a navy boat with sailors not specifically trained for rescue. They didn't have even life saving suits. If they had then probably that sailor would not be dead. They all come to help and have done the best they could for some sailors that were doing the wrong thing and that could be safe sailing offshore.
This starts to be a problem, I mean sailors doing things without knowing how to them and then ask for help:
Yesterday the life boat from Peniche went out to respond to a mayday. The time as disagreeable but not threatening and today is a nice day. The saillboat in question had 9/10m and had a engine problem. I saw photos of the boat and its sails were intact and apparently without any problem. The conditions permitted the life saving boat to tow them to Port. Why the hell did they not sail to Port? Probably another ones that did not want to pass a disagreeable night at sea
