Question for information. Have always been taught that when drilling & bolting equipment down that whatever the size of hole drilled and tapped for securing that you should have the same amount of metal on each side of the bolt being drilled and tapped into the plate for proper strength of the securing plate. In you case they use a 1/2" bolt for example shouldn't there be at least a 1/2" of metal on each side of the bolt being used. As for a mechanical standard.

  • Page 3 This document is intended to give details and guidance for a boat builder or equipment installer to properly install the Seakeeper 1. The Seakeeper 1 can produce forces of up to 1,515 lbs. (6.74 KN) in the vertical direction, 2,248 lbs. (10.0 KN) in the longitudinal direction, and 1,697 lbs. (7.55 KN) in the lateral direction at each of the four mounts.
  • Page 4 3. While handling / installing the Seakeeper assembly, protect exposed hydraulic brake cylinder rods (see Figure 1) from scratches or damage as this could lead to premature seal failure and oil leaks. 4. Exercise care to protect any exposed surfaces as damage to finish could lead to early appearance degradation of the Seakeeper.
  • Page 5 Seakeeper noise has been measured under steady state conditions (no wave load) in Seakeeper's Engineering Lab and in our Factory Demo Boat. The steady state noise at 1 meter is typically in the range of 62-64 dBC un-weighted. As the frequencies emitting the highest sound pressures are low (like other marine machinery), it is recommended that the Seakeeper be installed in an enclosed space such as a leaning post / seat, bilge, center console, or machinery space.
