Thank Peter. I wondered if it could be teak oil that had been spilled previously somehow as it stained my hands and is the right color. This boat has a plastic shower seat and no teak below deck so it seemed like an unusual place to find teak oil or it’s residue. It is also more viscous but maybe that is due to slow drying? I have a fan blowing into the shower seat compartment and will see if it “disappears”. Thanks again.

Chris - I had the same on my 400. I am the second owner but the water was Brown , and slightly oily. Mine gathered in the Bilge under the Galley sink, it had a strange smell, not bad or good but like a 'woody smell ' .
I do not know how the water ended up here?, but I came to the conclusion that it was swishing around the bilges and gathered up all the dust, wood chips, and other small amounts of oil or residue .. I sponged it out , and it has stayed away, - the smell is still there, but this winter I am going to remove the floor boards and clean all the bilges with Bilge X .

Thanks for this. Sounds like your challenge is of the exact same nature but slightly different (perhaps) location. I have cleaned out every accessible area - under hot water heater, below the muffler/exhaust, bilges, under sinks, by fresh water tank, etc. Smell still remains. Pls keep me in the loop as we try to fix this. The smell is not intolerable but makes me think something is not quite right. Thanks!

One source of this problem has not been mentioned: a separation of the seal between the hull and the liner where the saildrive attaches to the engine. A slight break in that seal will allow sea water to enter sporatically depending on the forces on the hull. That water may be brown, smell woody, look oily as it picks up items left in the course of construction. Left unrepaired the separation will increase as will the amounts of water on board.

Its been interesting to read this and the many other threads on this forum about water in the bilges. I had two episodes, one serious the other simply annoying. The first was failure of hull valve sealants on post-purchase launch which in my mad rush to find the cause had me lift every single bit of flooring down below to find the cause as surprisingly you had to shine an angled light on the hull valve before you could actually see the water fanning out from 2 valves. The second is an ongoing slow creepage largely due to overflow from the FW tank, something I later proved on exploring the inside of the stringers with an endoscope.
I was concerned until I remembered my old long-keeler with its deep bilge that always contained water no matter how often it was pumped or the potential causes checked. The simple facts are that Bears poop in the woods and boats leak. The various posts are all valid; there are such a plethora of potential causes that its virtually impossible to eliminate them all. Rather, I'd focus on the rate of leakage and the type of fluid, bearing in mind that its often surprisingly hard to determine if water is salt or fresh just by taste; do it often enough and a leak will soon not be at the top of your worry-list. Logically identify the sites that may cause catastrophic leakage on failure and check them thoroughly; once you're reassured of their integrity then anything else falls into the 'nuisance' category. Sketch out and examine the cooling system, the FW system, all discharges and hull penetrations; check your SD water alarm works. If you wish place indicators that will show water at suspect sites or even get an endoscope and check out the bowels of the boat. Having reassured myself that all's good at the start of a season I then just check under the sink and lift a flooring board once or twice a month, inserting the nozzle of an oil-extraction pump into the stringers. Having established the 'normal' amount of leakage I'd only be concerned now if the level had risen dramatically. Its all valuable stuff, making you get to know the boat thoroughly for that time when something goes badly wrong at sea. Besides, my wife says she's glad I've got the boat as I've now no time (or money!) to spend on another woman. |

I have never checked my stringers , but with all the info you have mentioned , I better !! - does water get in here and not get out ?
Where should I check ? - or where does the water ‘usually’ collect ? - under my galley sink is dry , slight condensation - and a musty smell ... so maybe I need to investigate further and remove all floor boards .. Thanks for all this info .

If you haven't noticed water in the more easily visible spaces like under the galley then you probably haven't got any real concerns. The void spaces inside the stringers are pierced by approx. 3cm diameter holes at either end to allow water to flow through. In the 400, the overflow pipe from the FW tank empties inside a stringer in the main cabin. Hanse could have taken it back to the bilge pump area but then that pump itself is sited higher and further aft than the lowest part of the boat. I do like these boats but there are several design flaws we just have to learn to overcome.
I did raise all the boards when I had the issue with the hull valves and it was very informative; always a good idea to get to know the guts of your boat and I'd recommend you do the same. However, all I need do now is simply raise one board in the main cabin once or twice a month to check what's there and extract water if necessary. If the level rises to the point that it gets to the bilge pump I'd be very concerned and I'm re-siting the pump. |

Sorry - best board to lift in a 400 is the long one just inboard of the chart table. I keep this secured with just a couple of screws. Don't be too concerned, however; decades of different boats has taught me that they all leak one way or t'other…...
