Steve, soapy water and clean water can get into
any place that dirty smelly water can get into--or any place that your recommended solution of bleach and water can get into. No, it's not a job that can be done in an hour...put enough water and detergent in the bilge to clean, go sailing for a couple of hourse, tacking a lot...come back, drain it...flood with clean water...go sailing and tack a lot...come back, drain...add more clean water, go sailing again...till the water sloshing around in the bilge is clean. It's a day's work, but it can be done and SHOULD be done at least once a year. That Hunter neglected to drill limber holes doesn't make their absence sacrosanct...blaming Hunter is just an excuse to avoid the work necessary to put them in yourself. That may require cutting and fitting some hatches in the cabin sole, but a cabin sole without hatches isn't sacrosanct either, and having both hatches and limber holes would certainly make keeping the bilge and grid clean a LOT easier. And btw...re-routing the icebox drain into the bilge only contributes more bacteria and smelly water to a bilge that's already full of dirty smelly water. It should go into a sump that's easily accessible so it can be cleaned easily when it starts to stink.
