In the meantime, i sewed all the bad spots on our canvas, first, tho whole thing has to come off, then maneuver it all into the boat, set up the Sailrite sewing machine, and redo all the seams that are falling apart.   It wasnt too bad really, i had done some of them already in the past few years, but the canvas was very dirty, especially the side towards the land, so it took quite a bit of scrubbing, with a nylon brush, ( so as not to break the cloth), but its looks great again for another 6 months.
