Sorry, no pic. I use the heavy poly Hay tarps. I buy a 20' x 60' for $200 and they hold up well as long as i use foam pipe wrap and carpet padding where ever it may contact any kind of sharp edges. Thats the secret. Cover all kinds of edges. The wind will kill a tarp.
My mast is stored in a rack i built 5' above deck; this way i can drape the tarp like a big tent and tie it up tight. I do leave room for ventilation up front and have access in the back for access so i can do my routine work.
Super Sunshield Hay Tarps for Extreme Protection
I didn't buy from this place. Some hay tarps are better than others i have discovered.
