Don't know about the water ballasted h26s but most boats have more than a few gallons of water trapped in the hull stringers below the sole. The sources of this water are usually rain leaks, wash downs, galley spills, sea spray, wet bathing suits, plumbing leaks, condensation, through hull leaks, showers, ice coolers and refrigerators discharge. Depending on the source the water and its routing, it will flow at different speeds with clearer water reaching the bilge faster while some of the water remaining and festering deep in the hull. Water contaminated with diesel fuel, oils and bacteria will foul. Besides collecting water for discharge, the bilge also acts as a P-Trap keeping most fouled water smells from entering the cabin. Attempting to dry the bilge can be a seemingly futile endeavor as soon as the boat gets in motion it will release some of the trapped water and quite soon it will be releasing some of the fouled water with all its smells and nastiness. I try to correct rain leaks, stop any plumbing and thru-hull leaks and control packing gland drip and as far as the others I continue to enjoy boating without minding them. I do keep the backflow level on the bilge which gets refreshed every time the automatic bilge pump expels the excess.
