I don't think it's lack of skill, but rather a different kind of skill. There's huge skill required to push those modern boats around as quickly as they do. In my mind there is no question they are extremely talented, excellent sailors.
There is the aspects of ever increasing technological dependence/use. I think the weekend sailor that goes out extending their range well beyond the abilities aided by technology is another question, and I think perhaps the one you are referring to.
If I am heading off shore, I'd take a Volvo Ocean race sailor (for example) with no qualms. Just some of the usual 'find out if we are compatible' type questions.
Now if it's a weekend sailor who tells me he has done some ocean sailing I will be asking a shit-ton more questions. That experience won't be a green light from me. A while lot of needed hands on knowledge will have to be shown.
What an awesome experience to have actually sailed with Bernard M. I met him in France when they were inducting one of his sailboats into the museum. I met him after all of the hullabaloo and he was just sitting and chatting with folks on the docks.
