Can someone please tell me where I can get an inexpensive but reliable mooring cover that I can easily put on/take off from the mooring in the water? It seems like the covers online are for trailers, instead of mooring. I have a 2013 SLX staying in the water until September. The sun is damaging the seats, so I'd like to get one asap, versus an expensive, 3-wk wait kind of cover. Thank you!
