Question about boat covers
Please excuse my ignorance of the subject since I live in a warm climate area and don't have these problems, but why couldn't one build a total boat cover out of sunbrella that is raised with the jib/spinnaker and main halyards? The cover would go from stem to stern to allow winter work to be performed. Obviously, for wind reasons, you wouldn't want the cover to go very high up the mast, but what about to, say, two feet above the sail cover?The lower ends could have some arrangement of cringles and d-shackles to attach to the toe rail (or upper lifeline for those without) with an overlapping "hem" on the outside of the toerail to keep water/snow flowing outside of the boat instead of in. (Infinite combinations of drawstrings, ties, shackles, snaps, or fittings could be used to attach the cover to the desired edge of the boat and to keep the overlapping "hem" from flailing around and beating the gelcoat to death.) Sunbrella comes in 60" widths as well and is not that expensive. Of course, by the time you add cringles every 12-24", d-shackles for every cringle, and extra heavy duty zippers with overlying Vecro'd flap, I suspect the entire cover would be costly, but it would be something you could use year after year with proper storage in the spring/summer. In addition, you could actually put a "door" in the sunbrella with a zipper so you could access the vessel and perform work when you wanted. If any shore power, even for an extension cord, is available, bring along a ceramic heater and put it in the cockpit seat (if you need to work on deck) or in the cabin. Obviously, a drop-light would also be required. In fact, if you left a drop-light with a 60 watt bulb turned on inside the cover but up on deck, it might keep the entire cover warm enough to keep snow from ever building up on the cover. This would allow a little bit more heat available when you showed up to work on the boat? Then again, if you wanted some daylight to assist in the lighting effort, you could spend some more bucks to install plastic windows in the cover in strategic areas where you would need light to work. (Anchor locker? Mast step? Companionway? Cockpit lockers?)So, what are the issues: Is the amount of area too large that high winds would put the vessel at risk of being blown off the stands/trailer? Is the cost of this not worth it? Does sunbrella not hold up well to cold/snow/ice/winter? Are halyards removed for the winter?Just curious, please let me know what you think. If it's viable, I'll market it!
