I think if you took a survey on this, a majority of us have tried the tarp in some form or another and ultimately found that there is really no substantial benefits to it other than piece of mind. I think in the time you spent tarping you would be better off trying to mildew proof instead. Primarily, getting it as dry as possible prior to tarping. From what I have been reading on the other posts, the water between the floor/hull issue would make that task almost impossible. Putting the seats indoors and 303 the vinyl left in the boat was a big help for me. And another thing, anything touching the vinyl any time of the year will cause the black death to grow in that spot!
