Yes, world, Gary achieved 62mph in my landyacht (increased beam 5sm) under conditions I believe equal or exceeded my personal best of 64. I believe I had the tire pressure higher on my run on another occasion. And I felt pretty good about our attempts and thought my goal of getting mid 70's in a vessel you could put in the back of of a minivan was possible. But now, it looks like almost anything you put wheels and a rag on will hit low 60's. (Mantas, Scirrocco's, etc.) And I don't think there is much chance of me breaking 70 without a heavy investment in time and technology. Still, I look forward to our next attempt at mediocre results at getting 300lbs to go 60. Although the speedo only says 60 (you actually rarely get a chance to see it at that speed), your heart and sphincter organs say 200!
