Comment by ninalanyon 6 hours ago What's the advantage over a catamaran or hydrofoil ferry? 5 comments ninalanyon Reply nomel 5 hours ago Cavitation limits hydrofoil top speeds to ~60 knots. Although, there's a neat profile that just ignores top surface lift entirely [1] (probably at the expense of drag?).[1] https://www.metstrade.com/news/sustainability/record-hunters... IshKebab 2 hours ago Isn't that basically how supercavitating torpedoes work? bruce511 6 hours ago Speed. 290km/h is pretty quick by maritime standards.And comfort. With a 1.5m swell, you're gonna feel that in a boat. A hydrofoil will still go up and down.Whereas a ground-effect vehicle is still flying, so a lot smoother. nradov 6 hours ago Hitting a partially submerged log or lost shipping container is pretty rough on hydrofoil ferries.
