Wood wheels on mostly white fiberglass boats are pretty not in high demand. I don't think your going to get rich on your idea. Even over on the wooden boat forums I started a discussion some time ago. Wood wheels are just not that high on the list. Epoxy encapsulated wheels won't last longer and will still suffer the effects of weather, water and temperature.
There are hundreds of places selling wood wheels that are decorative but not made for actual use on a boat.
Your wheels are metal wheels with a wood rim. big difference then real wooden wheels
here's a build in lamination, don't know the language.
