Hey Smackdaddy, thanks for the welcome. Just so we are clear, I was not referring to any page on the JSD site as bollocks, although they do perpetuate some ideas concerning sea
anchors that I am at odds with. My previous post might well be rubbish. It is a theory of unknown origin that seems to make sense, but may be inaccurate or incomplete in the re-telling and I don't know if it has ever been tested. Whatever the case, there is something going on there. I had intended to make some edits to reflect that, but you'd already quoted it in its entirety so I'll let it stand.
Cheers
Peter
