I was wondering if any of the WW brain trust has seen this before and might know what it is. I have a 2001 Chaparral 205 SSE with Beautiful white and yellow vinyl interior. I keep it in premo condition and there is not a scratch or nick in it, it looks like the day it came off of the production line. I keep it clean and protected with a vinyl cleaner and protectant made by Boat USA and have been very happy with the product for the 10 years we have owned the boat. However, 2 years ago when I pulled the cover off of the boat after its winter nap my heart dropped when I seen the huge stain on the back of the engine cover vinyl. I tried everything that I could use on it but the stain was not to be removed. I went in and told my wife that our beautiful white vinyl on our boat now looked like something you pulled out of the dumpster. The next day when I got home from work my wife asked me what was wrong with the boat, so I took her out to show her and it was totally gone, back to a brilliant white like new. One day in the sun and it goes away. Since then I have tried putting towels under the cover in that area, elevating the cover, and so on but if the cover is on it for a week or more the stain returns, getting worse the longer I leave the cover on. Every time though, if I let it sit in the sun for one day it completely goes away. Have any of you seen this before, know what it is, and know what is causing it. See pictures of the stain and what the interior of the boat looks like after a day in the sun.
I have come to the conclusion that it might be a mold of some sort but I am very careful to make sure that the boat is completely dry before I cover it or store it for the winter.
