Marine sanitation holding vessel

A marine sanitation holding vessel for collecting and storing waste material, comprising:

• a. a barge having an upper deck, the barge defining first and second end compartments and a storage compartment, where the first and second end compartments are filled with material that provides buoyancy to the barge and the storage compartment contains waste material;
• b. a filter compartment mounted on the upper deck of the barge, the filter compartment being in communication with the storage compartment;
• c. a hollow mast having a first end in communication with the filter compartment and a second end extending above the upper deck of the barge;
• and
• d. means located in the filter compartment for filtering air passing from the storage compartment, through the filter compartment, and out of the hollow mast;
• e. the filter compartment being arranged relative to the storage compartment and having a maintenance opening therein such that the air filtering means can be removed therefrom to allow cleaning of the storage compartment.

• wherein
• e. the filter compartment is defined by a housing having an upper opening and a filter cover rotatably attached to the housing to selectively cover the upper opening, where the hollow mast is so attached to the filter cover that hollow mast rotates between:
• (a) a lowered position when the filter cover is open;
• and (b) a raised position when the filter cover is closed, where at least portions of the vessel may be serviced when the mast is in the lowered position.
