I suspect
Someone would have a problem with that boat on the lake.
There is ALWAYS Someone.
From the Speed numbers I have been able to find it looks like the Vestas boat reached 102.92 Kph/63.95 mph. Other than speed on the lake, the problem I think would be the Beam of the boat ...combined with the Speed...

Lets not forget OUR
"Sensible" 150' rule. .......Wipeout those idle Bayliners
Another note: The Vestas boat waited for good wind on windward shore to avoid seas. They had the advantage of strong wind just downwind and over a beach,....SO NO Waves.
The French have ALWAYS been the leaders/inovators in
Offshore and particularly
Single Handed Long Distance Offshore racing . ie:
Round The World
EDIT: Lets not forget the
UNITS of Conversion. MPH to Acres Per Second....

NB
