I’m no physics expert but I’m told water has a speed barrier and that coming of as vehicle into water at speed is like hitting concrete, the thought of going this fast in an unpredictable environment (waves, or ‘big ripples’ in a lake) would be super scary
- gwill 4y agothe "lake" is long dried out. this was done on land in a vessel with a cockpit. there's a video toward the bottom of the article.
- nonfamous 4y agoLake Eyre is dry most of the time, but does fill briefly every few years. Notably, the reason why Mad Max Fury Road was filmed in Ethiopia instead of Australia was that rains filled the lake a week before filming, and turned the desert into a field of wildflowers unsuitable for the apocalyptic setting.
- trillic 4y agoThe current limitation of in-water sailing vessels at the moment is cavitation. Cavitation is the process by which the pressure of water is reduced so low on the trailing edge of a foil at high speeds that the water instantly boils, turning to vapor, making your lovely laminar flow over the trailing edge of the foil turn into a turbulent flow. No fun if you were nicely balanced ripping along at 40 kts on an AC75. Now only the leading edge of your foil is working, it needs a higher angle of attack to maintain the same lift, which increases the drag, slowing you down and causing your owner to cry into his billions of dollars because you just lost him the America's Cup.
