Chris is changing the game here guys ONLY USE WHEN NOT ON THE WATER! : "I made these hatch fans to get my boat hull super dry. Inevitably sailing an older RS400 all year round I get some damp in the tanks so to try to keep it down weight I use these regularly when it’s a warm/dry day.
Easy to make from a hatch cover, computer fan and battery pack. Very quick to use, just swap out the front hatches and remove the rear bung for airflow through the hull. A lighter/dry boat is a fast boat."
