What this video covers
Nikki and Jason Wynn document how their aluminum explorer yacht handles sub-freezing winter conditions while moored in the Netherlands, walking through every system that keeps the boat warm, dry, and undamaged at temperatures down to 20°F (−7°C).0:10
The primary heat source is a Cabola diesel heater — described by Dutch sailors as the gold standard for marine heating — which circulates hot fluid through radiators and underfloor pipes throughout the boat, running off the same diesel tank as the main engine at over 90% efficiency.8:22 Three additional radiators protect the engine room, generator, and batteries from freezing.2:56 A heat-pump system serves as backup but stops working when water temperature drops below 40°F; a plug-in electric space heater supplements on shore power.12:44
Condensation is identified as the biggest winter-boating challenge.6:09 The boat addresses it with 1.5–2 inches of closed-cell spray foam insulation on the aluminum hull, double-paned windows throughout (single-pane hatches and portlights remain a problem they are still solving with improvised bubble wrap), a continuous ventilation gap between hull and interior walls with a circulation fan, Dorade vents in the owner's cabin and saloon, and a proper galley exhaust vent.16:22 Cork decking provides exterior thermal insulation and grip.1:07 The 7mm aluminum hull is ice-rated, unlike fiberglass or carbon fiber, which become brittle in freezing temperatures and vulnerable to ice impact.23:42
