Is it comon to have diesel odors on sailboats that run a diesel engine? The few sailboat that I have been on really smell of diesel. The boats were older and when I do decide to buy a sailboat it will probalby be a boat from the 70's early 80's in the 36-38 foot range. Is there something that can rid of these odors? I think it would be hard to sleep on the boat with the odors. Thanks.
