This might sound like overkill and a lot of trouble, but it works great for me. I place cheap cotton towels on the carpet, covering almost the entire floor. On top of the large towel at the back, I place two rubber backed "welcome" type mats to catch most of the water from the skiers getting into the boat. The towels on the floor on both sides of the motor box catch water from skis, boots, gloves, and jackets. After skiing, pull it all out and place into the sun to dry or into the clothes dryer if I am in a hurry. I find that this takes care of at least 95% (seems like more) of the water that would have been in the boat, and I can put it up almost dry. I have it down to a routine, so it is just part of cleaning the boat after each use. Never had a problem with mildew or odor in my 22-year old boat. My boat is kept covered on a lift. You will be surprised how soaking wet a thin cotton towel can be and the carpet underneath can be nearly dry.
