The core advantage of gooseneck ventilation ducts over straight-tube ventilation systems is their superior backflow prevention performance. Their curved neck structure forms a natural barrier, effectively preventing seawater, rainwater, and debris from entering the ventilation channel. Straight-tube ventilation systems, lacking this barrier, are prone to seawater backflow.
They also offer better resistance to wind and waves. The curved structure disperses the impact of wind and waves on the ventilation duct, reducing damage to the system itself. It also prevents wind and waves from directly entering the cabin and causing sudden pressure changes. Straight-tube ventilation systems are more susceptible to direct impact from wind and waves and have poorer stability.
Furthermore, they offer advantages in sound insulation and noise reduction. The curved channel reduces the transmission of external noise into the cabin, lowering the impact of wind, waves, and ship machinery noise during navigation on the cabin environment. Straight-tube ventilation systems have a smooth noise transmission path, resulting in poor sound insulation and affecting cabin comfort.
