I am rerouting all tank vents to my pilothouse roof from the "usual" spot under the rail on the hull for exactly this reason, and my plans include a sort of drip loop and petcock just before the final vertical run, plus of course a gooseneck on top. All this will go inside brass poles doubling as handholds inside the pilothouse.
In a similar vein, I am going to have a shut off on my starboard side waterline exhaust
so there is no chance of water ingress back up the exhaust
circuit if we are sailing well heeled. The shut off lever will engage a circuit on the engine
key, so if the exhaust is not open, the engine
I could rig a solenoid for this, but I prefer all manual. It's also a sort of anti-theft device as few thieves would think (and would find problematic to access if they didn't know about it) a long rod that leads to a yoke that opens and closes a seacock behind a tank.
While this is interesting (ATTWOOD Vent at West Marine
), I find, having done a few kerosene flushes due to failed spring and piston combos in anti-siphon loops, that I am happier with straight hoses and high-placed goosenecks if the object is simply to bring outside air pressure to the inside of a tank and to allow a way for condensation
On a lot of modern sailboats, this is going to be aesthetically displeasing (although one could run the vents into the lazarette out of sight and water), which is why I chose a steel
pilothouse, where such considerations aren't really an issue as the thing already looks 3/4 trawler
