Personally I have no experience with convection but my step son and wife have one in the house...all new cookware of course! They love it especially that it stays cool. However she is constantly wiping the top since everything is by touch...set temp, turn up or down so the black top is covered in seconds with finger prints and she is an obsessive neat freak! I would think that glass top would be slippery with the least movement? At least steel grates are far less so and it be useless if the boat is in even a small sea.
