Ive always just propped open the rear lid with something small to vent the area, then put the cover on the boat, and plugged up the charger on an outdoor timer (Full charge after fishing, then timer charge after that). The timer turns on for 15-30 minutes per day, and you dont ever have to think about plugging and uplugging your boat. Never have to take cover on/off either. Hope that helps.
