I would find out if the marina owners are in agreement with the marina manager then go from there.
Though it seems that if the marina has vessels that are residences then they must accommodate the OCer whilst the citizen transits to his property. Not unlike a apartment complex.
I suspect that the Virginians who post here are more familiar with "safe passage" laws and will be able to give you a definitive answer to your question.
As always, your money, your decision.
Good luck and keep us posted.
