"Sump-less in Portland"
Our Olson 34 has an arc-shape bottom in the midsection of the boat. No sump - zip - nada. First wake-up call was when we were rail down, driving to weather, and I found water in the storage shelf beside the nav table seat! It dawned on me, belatedly, why the fabric hull liner was water stained...
Within our first two years of ownership, we installed a PSS no-drip shaft seal. With no water migrating forward from the old stuffing box area the situation improved markedly. Nowadays there is some fresh (!) rain water in the winter from the inside of the mast, and sometimes a little bit of water from condensation from the refrigeration copper lines under the galley counter. I sponge out all moisture from the 5 inch deep bilge.
FWIW, I know an offshore cruiser that puts a large sponge in each bilge section and wrings 'em out regularly.
As a friend used to tell me: "a dry bilge is happy bilge."
