If your boat has thru-hulls below the waterline that can’t be closed, it should be stored ashore for the winter. Raising and refurbishing a boat that sinks is a daunting job that can keep the boat in the repair yard for many weeks over the spring and summer. And all thru-hulls, especially the ones for the cockpit drains, must be double-clamped with stainless steel hose clamps at each end. When water freezes, it expands and will lift a poorly secured hose off a fitting. A thru-hull is a fitting designed to accept pipes, hoses or valves to allow water to pass in or out of a vessel. Most of the thru-hulls above the waterline do not require having seacocks. Thru-hulls above the waterline are not required to have seacocks and most don’t. That doesn’t mean that these thru-hulls aren’t vulnerable.
Ordinary plastic thru-hulls crack and deteriorate in sunlight, but that won’t sink the boat until the weight of ice and snow in the cockpit forces the thru-hull below the water. Plastic thru-hulls near the waterline are especially vulnerable and should be replaced with bronze. Plugging exhaust ports will also prevent unwanted guests from finding their way aboard. There have been several claims involving muskrats chewing their way through parts of the exhaust system, sinking the boat. Bilge Pumps If the bilge pump runs, it means your boat is taking on water or, to put it another way, your boat is sinking. There’s no acceptable amount of leaking. Make sure the bilge is free of any debris or oil that might clog the pump or interfere with the switch, and that the bilge pump is wired directly to the batteries so that it will operate when all of the switches are turned off at the main panel. Also check the operation of bilge pumps. After you’ve cleaned the bilge, add enough nontoxic antifreeze to trigger the float switch. Bail or sponge the remainder out.
Shrink wrapping kits prevents damage from extended exposure to heavy weather and road grime. Unlike a tarpaulin, because the shrink wrap fits so tightly, it cannot fold, which is the secret of its durability. Whether you are carrying your asset by low-loader, trailer or as deck goods it will become visible to the components, ecological features and other threats. We aim to guarantee customer satisfaction. From our warehouses, we specialize in supplying shrink wrap materials. The structure is complete; a single piece of plastic is cut and draped over the boat. The plastic must then be wrapped and heat welded together to create a snug fit around the top and sides of the boat. Fully automatic stretch wrappers can decrease the number of employees and time needed to centralize. Steel supports are best, but timber frames will also do the job if they have been inspected for declined wood and rusted closures. The shrink wrapping kit will require some alteration to improve adjacent support before they can be used for winter storage.
