Main bilge remains dry with a slight pleasant odor. I say pleasant, since growing up on a milk farm, my olfactory senses can tolerate odors that others find highly offensive. It seems what little seawater appears enters from the stuffing box. That water first enters a stringer space between the main bilge and the one beneath the shower sump. It will first spill over through a limber hole into this bilge area before overflowing into the main bilge, so I make it a practice to extract what little water (maybe a pint) appears in these two areas when I complete each daily cruise.
The aft cabin shower sump water is the one most prone to stink if left for a period of time, because the pump float switch leaves about a quart of soapy water. Showering every other day keeps the sump water cycled before any rotting can begin. After the first rotting experience that stunk up the boat several years ago, I now dry out the sump at the end of each cruise. Otherwise, if left, the boat will smell like a rotting roadkill carcass in a matter of a few days.
I do need to clean the bilge area again and will use a cleaner that has worked in the past. I place a small weight on the float switch, pour fresh water into the bilge until the dirty area is covered, then add the detergent and blend. After a day of cruising, that action will spruce up the bilge nicely.
