You would be surprised how many times this comes up.
Do you detect a smell when you are on your boat? Face it….
DOES YOUR BOAT HAVE.......BO ? (Boat Odor)
More often than not, if you do, It’s most likely coming from the bilge.
The bilge collects everything dropped, dripped, and spilled on the boat. If your boat’s bilge has been neglected, pouring bilge cleaner in and closing the hatch may not fully resolve the issue.
You’ll need to roll up your sleeves, remove all the debris, and then scrub the bilge. Rinse THOROUGHLY with hot water, and if necessary, repeat the process until the inside of the bilge is thoroughly clean.
There are no shortage of environmentally safe products that are good at degreasing and eliminating odors. Cleaning the bilge is important, but if done routinely, it should become an easily accomplished and quick fix.
If elbow grease and the proper products don’t eliminate the odor, I recommend checking the vent hose from the holding tank. If it is compromised or if the fitting needs to be tightened, it’s a quick fix. Should the odor become markedly stronger and fouler, after the holding tank is pumped out, you may need to replace the hose from the holding tank to the outside pumpout fitting (this is a common issue for older boats).
