2003 Carver 466. Just noticed a small, but steady and continuous stream of water exiting from underneath and 1 1/2 ft back from the front edge of the swim platform on the port side. Inside the platform is dry and completely above water. Aft salon and master cabin a/c are off and the grey water tank is empty. No visible leaks from the sink, shower, head, a/c units or washing machine. No recent rain or wash jobs. Has anyone experienced this? If so, do you know the source? Does it have a purpose or can it be stopped? Photo attached.
