Water is considerably different to air and there is no analogous effect for ground effect in water.
Edit: I realise now that you mean hydrofoil as in the boat rather than the submerged wing (it's confusing that they both have the same name). I don't think the ground effect from the boat's hull contributes much to the lift but it is something that the designers of the AC75 boats take into consideration https://www.sailmagazine.com/racing/36th-americas-cup-different-design-approaches https://www.sailmagazine.com/racing/36th-americas-cup-differ...
- nixy 5y agoI think the OP is referring to ground effect above the water surface, as employed by for example eraknoplans (https://en.wikipedia.org/wiki/Lun-class_ekranoplan https://en.wikipedia.org/wiki/Lun-class_ekranoplan)
- jojohohanon 5y agoI would speculate no, as it seems a trade off between inherently stable and inefficient (standard v shaped hull) and inherently unstable, but more efficient (inverted v). Ekranoplans have wings and aerodynamic control surfaces. I also wonder (this may be the primary reason) if the speeds a hydroplane achieves are sufficient to generate much lift in air from something the size of a boat hull.
