The Hydrotab interceptors are characterized by extreme robustness and total simplicity in construction.
The system is open without any sealing parts.
The housing is constructed by high quality Inox 316 stainless steel, while the air chamber is made of synthetic multilayer material highly resistant to high pressure (up to 30bars) and appropriate to sea water. High shifting forces applied to blades makes interceptors highly resilient to barnacle/marine growth and practically indestructible even after hits and bamps with floating objects,
