Smell

Apart from fresh air: I have replaced all the waste pipes from the heads in my boat and that really helps too. When they get old the smell percolates through the hose wall. On top charter boats they routinely replace all the hoses every 2-3 years. Also, fabric conditioner in the bilges to make everything smell nice.
 
I had a pong going on in my boat. New to me last spring but a 1999 vintage. A waste tank smell. I had a burrow and pulled a panel out to find the waste tank, it was stinking in the compartment. The tank, never used by the previous owner, had vile contents of a serious age and turns out that it had been leaking into the plywood base that it stood on and into a void in the hull.
pulled the tank out, very carefully as it wouldn’t empty, emptied and sterilised it. Replaced all the hoses and refurbed the heads pump. Also cleaned out the 5-6litres of fetid water and “stuff” from the void beneath the rotten plywood base that I had ripped out. The pics show before and after in the boat and the fetid stuff in a bucket.
I used a load of bleach and floor cleaner in the hull then two coats of Zinsser6611C0E2-B16D-454C-964C-7BEB30088BAE.jpeg42C1A3B0-0891-4D3B-8728-A556B942EA44.jpeg47D15C14-762C-4C82-A6BF-50C890BE628F.jpeg Cover Stain to seal it.
 
I had a MAB that smelled like one. Chlorine bleach spray into all lockers and bilge, plenty of Febreze on all soft furnishings and then more into lockers and bilge. It used to work for a couple of weeks.........?
