Is this a dock box?

Question

Did Supreme products ever make fiberglass dock boxes. I obtained what looks to me like a dock box and it opens from each side. It is white fiberglass and has the words

'supreme core' on it.

Our marina is very adamant on white fiberglass dock boxes. Last year someone tried to pass off a wooden retagle box painted white and they were made to remove it.

Answer 1

It seems to me the issue is: What does YOUR marina define as a dock-box !!

I lived in 6 different marina's in San Diego, and Redwood City California over the years.  SOME had built in fiber-glass dock-boxes and wouldn't permit ANYTHING but a simple stair-set, and others permitted an additional dock box AND extensive stairs dock-box

In Penisula Harbor, I made several combination stair/boxes from marine-grade plywood, that were FINE.

GOOD LUCK

Answer 2

Take the photo to your harbor master and clear it with him/her. Explain what it is made of, how big it is, and the brand. They should clear it for you. If not, ask them for recommendations.
