When I started cruising aboard a 26 foot, tiller steered sloop. I learned the value of simplicity. Fewer components meant that there was less to fail and fewer things to fix. Despite all the upsides of doing more with less, I dreamed about a wheel-steered 40 footer and days spent surfing down trade wind seas. […]
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.
