Maybe I am dumb, but it seems that I could break that record, with a ski in FLAT water, making loops around a calm lake... loops of around 50 miles each. This way, you have a 5 min stop once per hr, for water, and gas, and your risk is less, because you re never far from shore. But, as you know, YOU did it, and I did not!
Anyway, I predict that someday this record will be up there around 800 miles, with a super fast ski, and some flat water.
Thanks for sharing. It takes a spark, and then on we go!
