I have a 33 hunter cheubini I picked up last fall and have been slowly going threw stuff .. I notice the bildge pump drain hose were it exits the hull comes up from underneath but loops above the thu hull fitting than down than out is there a reason for that ? splash back? acts like a plumb trap?..seems kinda tight and subject to crack hose there... or just sloppy wokmanship like the wiring which is another nightmare that needs addressing

Most electric bilge pumps won't prevent water from flowing back through them, so the high loop is probably to prevent water from pouring in through the bilge pump when heeled.

Boats have been sunk in the past by siphoning water into the bilge pump hose. Ideally the outflow through-hull would remain above water, but as mentioned this may not be true with a heel. Some vessels, including my own have a loop as you described and additionally an anti-siphon valve at the top of the loop. 'take care and joy, Aythya crew
