Yuck!! You are a much braver soul than me to buy a boat with someones sh!t on the floor. Are these snap in carpets? If so I'd pull them and take a power washer to them. If they are not snap in I'd probably still take a power washer to them!! Or some sort of sanitizing cleaning machine.
As for the vinyl are they dry rotted or still soft and just dirty? If dirty go to your local marine store and get any number of heavy duty vinyl cleaners and medium bristle brush. Starbrite makes good stain cleaner for vinyl.
Post some pics so we can so we can see what you have on your hands and maybe give better advice.
