Harley - Class Rule excerpts for reference:

5.4 Deck Gear. No additions, relocations, or modifications are permitted except as herein provided.

5.4.1 Permitted Alterations or Additions:
.....
5.4.1.4 Deck prisms and/or ventilators which must be watertight when sealed shut.
.....
5.4.1.10 Substitution of plastic for wood toe rails.

So it appears that your opening ports are class legal if they are watertight when closed, but the metal toe rail is not class legal. If you want to discuss this as a potential rule change, please post it in the One Design Class Rules forum.
