The only solution when it comes to keeping your Racing Yacht dry when not sailing. The Stainless Steal Dehumidifier combined with the 31 North Hatch Cover can extract a whopping 12L of water from your boat, in just 24 hours. The Desiccant dehumidifier 'fires' moist air out of the boat via a 45mm pipe, so there is no need to try to drain a hose out of the boat or into a bucket (which we at 31 north essentially see as pointless) and then it pumps warm dry air back into the boat via a 120mm duct (literally the perfect scenario), so its good bye to any heaters down below! We can supply an analog timer that not only can save you on power, but it can be timed in with the operating hours of the boat yard to provide an even safer environment for your boat. A must have combo for anyone who is serious about their racing and cares about their boat. The 31 North bow cover is specifically designed to work in conjunction with the Ecor Pro and has an 'extreme seal' across the front of it that seals to the deck to stop water ingress through the front hatch, a mast gaitor, and a simple design that allows for access to the bow.
