Both took roughly the same time - PMY did it in seven hours, my crew of four in a plastic pilot gig called Angela in seven and a half. With four of them powering a boat more than twice as long they should have been a lot faster, but they were inexperienced rowers and had run a relay from London (about 30 miles each) the day before.
Spot the difference in the courses the boats took.
The other major difference in strategy was that PMY did careful calculations on a paper chart, whereas Mike Oram, the support boat skipper for Angela, just set his autopilot to take us straight over.
I don't think any of that all that much difference - as far as Angela was concerned, the dominant factor in choosing a crossing time was the current dramatically changeable weather, making finding a day when it wasn't going to be blowing a hoolie and lashing down with rain something of a problem.
In the event, the weather was dry and bright, with a fresh breeze and a bit of lumpy swell left over from the depression that whizzed through a couple of days before.
Lots of pictures here.
