With $655 million dollars marine vessel insurance claims from the 2017 hurricanes Harvey and Irma, there is no shortage of broken boats accumulating in salvage yards. The nations three big damaged boat liquidators - Certified Sales, Cooper Capital and U.S. Auctions are gradually thinning out their listings from Irma and Harvey, but Florence will surely bring a new crop. But just how salvageable are these boats?
The tools and materials required to maintain and repair everything on a boat will barely fit in a room. Just the kit required to maintain vital systems will raise the waterline of a large boat and is impractical in a smaller boat. Fortunately, when day sailing and even cruising locally, all we really need to do is get back to the dock...any dock.
As ventilation experts explore ways to make indoor spaces safer during the COVID-19 pandemic, we became curious about ventilation in our boats. As it turns out, where we install our exhaust or intake vents (portlight, hatch, or cowl) is just as important as what type of vent we use. Just as we can use the suction on the leeward side of a sail to pull the boat forward, we can use pressure differentials in the air surrounding the cabin to maximize the ventilation. Understanding the pressure differentials created by the flow of air over our boat’s deck is vital to the success of any passive ventilation scheme.
