The Seep has a fair bit of freeboard with a light load. The open lid on the forward deck allows air to go to the radiator, and the air exits thru side vents just under the canvas splash curtains. In surf or rough water, the deck intake and side vents can be closed. Air is then drawn in from under the dash and exits thru a vent that opens just above the dash, but airflow is limited and overheating can result. Spinning the wheels at the same time as the prop adds a little speed, but puts a heavier load on the engine. Spinning the wheels alone can deliver a speed of about 1.5 mph.
