A retractable deck pin for cooperating with a boat line includes a cylindrical pin body which is axially movable in a pin guidance by an underdeck positioned actuator. A seal element is positioned in a clearance for sealing the pin body with respect to the pin guidance. The retractable deck pin is improved by providing a reservoir filled with an oil volume. The reservoir which is positioned under the pin guidance has a reservoir opening for receiving the pin body in the contained liquid volume. An air inlet is provided with a non-return air valve. When moving the pin base into the liquid volume, an air volume above the liquid volume will get pressurised. An airflow escapes from the reservoir via the clearance to the ambient. The air flow through the clearance counteracts a possible incoming flow of leaking.
