Bedding
We did the same as Mark. However, we found it is important to have a mattress that is vinyl covered at all points that come in contact with the boat, ie; the bottom and sides of the mattress that contact the wood or fiberglass. This makes it easier to remove any mold. We do not leave bed coverings on the bed when we are not on board. Worse mold is when on board and heating the inside on the boat.
