Abstract
A deck ventilator suitable for small vessels is formed as a low dome 12. Outside air may enter it through window 14 and then circulate around member 30, through orifice 22 and down duct 7 which pierces deck 4. Member 30 usually serves merely as a shield against spray, however if a surge of water enters compartment 18 the orifice 22 is closed by movement of member 30 which is slidably hinged to U-shaped rods 23. This closing movement results from the combination of the impact of the water on member 30 and the member's inherent buoyancy.
