You have to protect the floor with something. The finish being matte or gloss shouldn't have a bearing on it. However, the placement of the slats (gaps) will prevent you from stepping on one lone piece of wood unless you have very very tiny feet.
Wow... long dead thread revival Somewhere I had a pic of original floorboards. Can't find it at the moment but they were nothing fancy, just painted marine ply that covered the area between the outer stringers, with some supporting and leveling cross pieces under. Harder to find or fabricate are the slick little clamps that held them down. They slid in to a slot from the sides and hooked under the outer stringer.
[Edit] Found what I was thinking of...

Some have no floorboards. Some have plywood as original and some have taken it to another level with teak, mahogany etc. Most of us have the skill level, but you might post some prints of what you have in case someone might be interested. Always nice to have resources. Thanks for the offer.
