this summer on a hot day working in my boat was very hot...so I instaled a boom tent...as soon as it was up you cauld feel air mouvement thrue the cabine...so I figured why not instal a tent over the front hatch
thing when I did the nice gentle breeze stopped...my girlfriend accidently triped on the bungies holding the front tent and it slipped off the hatch
...the airflow imidiatly started again.
is it possible that when the sun heats the bow...heats build up in the V-berth and raises out the hatch fast enough to creat airflo inn from the companionway
across the cabine...and sins the air under the boom tent is shaded and cooler a breeze is created??
anyone noticed this or its my imagination
