what is the recommend height then over water if I leave the VPS enabled
As was discussed earlier in the "yo yo" post, which his problem turned out to be prop or gimbal guards I believe, the vps does not work well over water, so I turn it off, especially since some of my video is done 1-2 feet off the water and under tree limbs. But if you have no obstructions above you I would say go what ever alt you want and if the sensors start seeing the water surface it will just rise.
