I’d use a PBR material with normal map on the ground plane. I gave the material that I created the name Deep Water on GP.rmtl (514.1 KB). Play with the size of the texture mapping on the ground plane to get the waves the size you want them to be.
Play with the material opacity to change the color action
I added further an environment using the tonemapped 8k jpeg for lakeside on HDRI haven for custom reflection and custom skylight. The sun was added too.
The sail is a simple PBR material with Subsurface Scattering enabled.
Inside Rhino you could still of course play with post effects
For big waves you can always quickly generate a mesh in Blender for that, took me less than a minute. Just a simple plane with ocean modifier applied, tweak some settings of that modifier and export as OBJ, import into Rhino. (The sail I also did in a few minutes using cloth modifier and a wind force).
