My new Mainship 34 T 2006 has scuffs above the water line the yard I am at now said it was from the shrink wrap last winter. The boat was stored with the same yard since new except last winter where it was stored by brokers yard. I believe this is where it happened . Current yard puts a band of plastic below the rubrail and shrink wrap is on top of this band to prevent abrasion.The survey did not show any of these damages prior to storage and I took delivery of the boat from Canada into US during the travel restriction. I did not notice it until I had it on my mooring. I thought it was from the mooring ball. My question is if the scuffs are not through the paint color can they be polished out?
