You are thinking about a slow boat in displacement mode, or a wave-surf board with very small fins. But I can tell you that the wetted surface area of my wing-foil board is exactly zero after takeoff, and all wet surfaces of the foil are, f

> Surfboards will have a Reynolds number of 10^7 which is entirely turbulent. A fin, foil or daggerboard below the board/boat is operating well within the range of Reynolds' numbers where laminar flow is relevant.

I'm pretty sure healthcare costs in the US are also higher as a percentage of GDP compared to EU, so higher wages would not explain the difference. Also productivity should be higher? I think pharmaceutical, hospital, insurance and leg
