Your're way off the mark!
B412,
Your concerns regarding lack of currency are well off the mark. All aircrew operating within a maritime environment are required to be HUET compliant. But it is not just the crew, those pers from the RDF (or any pers) that may be required to travel by helo over water are also required to be current. Those in the SASR are certainly up to date regarding HUET.
So let's not speculate about the recency of training etc. As those that have undergone HUET know, it is very different to any other sort of training or water based activity.
