...but I'd like to read anybody's thoughts on this, and on the worst wind-against-tide situation they've encountered.
I don't think it's just relative velocity that matters. Flow across the sea bed, through different depths and around obstacles will have an effect and so might the propagation speed of surface waves.
Worst I have ever been in - which does not necessarily mean particularly bad - was round the Mull of Oa at the SE corner of Islay. Yeuch. It's the only time I have ever had trouble with a towed rigid dinghy, which before I started tying it alongside on the high side (I was single handed, so tacking was fun) sank our times.
