Eye height all depends on the rig and how you are towing...but generally does not matter....they are usually placed for how a boat sits on a trailer.
Sure you can order a heavy duty one, install one or beef yours up..but if the are strong enough to pull a boat off the dry sand of a sand bar...towing is baby stuff.
Now.... as the dingy grows into a multi-thousand pound center console of say 25 feet or bigger, loaded down and twins....sure the forces start to rise where a custom tow eye or multiple tow rings are added is probably a good idea.
Boats with cored hulls just need to ensure the backing plate is substantial enough...usually eyeballing is enough if better than fender washers....but I have never had an issue with say Boston Whalers newer than from the 60s or back when the eyes were poorly installed.
