I recently had to remove the large tarp I had over my O-192; which is on a trailer in the snowy northeast. The problem was that the lifeline stanchions are at about the same height as the lowered mast, which sits lengthwise across the cabin top. The mast and stanchions formed "twin peaks" under the tarp, which lead to water pooling on top of the cover. This then froze, giving me a solid block of ice - about 100 lb worth, which was putting strain on the tarp, the stanchions and the mast. The ice was very difficult to remove; so much so that I haven't put the tarp back on.Anyone have suggestions or pictures of how a tarp can be put over the boat without creating this problem of water pooling on the tarp?
