  • "A hydrostatic seal provides control of a sealing surface taper as well as the cavitation reduction structure between the sealing surfaces. Control of sealing surfaces taper is provided through one or more relief recesses in the wall. Sounds complex, but it really isn’t."

  • "Underwater, the prop whine and the cavitation of hundreds of thousands of air bubbles radiate outward into the ocean. The sound wraps around the foreshores of Newfoundland, refracts off the temperature discontinuity of the Gulf Stream, and dissipates into the crushing black depths beyond the continental shelf. Low frequency vibrations propagate almost forever underwater, and the throb of the Andrea Gail's machinery ust reach just about every life form on the Banks."
