Teensie-weensie 12 volt fans move a lot of air...
...especially useful when underway in boistrous conditions when hatches and ports are dogged shut.In response to Melody's query, some Hela fans below really move the air. I have six (6) Hela 2-speed fans aboard -- one each in fwd head, fwd statroom, after cabins, and two in the salon (over galley and navsta). We usually use the low speed which is exceptionally quiet and minimizes the already increadably low current draw. I try mount the fans near a hatch or port so that, when open, they tend to draw air into the boat.PRACTICAL SAILOR gives Hela top recommendation. We concur - really increases the quality of life belowdeck. Stay cool--Ernie April
