The system works really well and I am thinking about making ducts to allow me to fit flaps on my MK2.
That won’t fly. A MK2 does not have a double bottom. Hence the water level inside the cockpit is below the level of transom flaps. But if the water is above the floorboards, I hear you say. Then the flaps are submerged due to the weight of the water in the cockpit.
The best bailer for a MK2 (and any other type): A scared men with a bucket.
