2.1 Mechanical Installation Introduction

The Seakeeper can produce loads up to 11,381 lbs (50.6 kN) at each of the four mounts and careful consideration should be given to foundation design to ensure it can transfer these loads into the hull. These loads do NOT include vessel motion accelerations, such as vertical slam loads which can be significant for high speed vessels. The responsible party for designing the supporting structure (boat builder, installer, or hired sub-contractor) must accommodate the above forces plus a reasonable factor of safety. Seakeeper recommends a minimum safety factor of 3.0 (yielding a Safety Margin of 2.0).” The Seakeeper 40 FRB supports Bolt-In and Bond-In Installation methods.

It is assumed that the installer is familiar with mechanical fasteners to marine structures and has performed structural analysis to assure the structure to which the Seakeeper mounts, can properly transfer the loads the Seakeeper creates into the hull structure. If the installer has any doubt about the ability of the structure to transfer the loads to the hull, then a licensed naval architect or marine engineer should be contacted to do a structural analysis.

The installer should review the following list of reference drawings to ensure the installation procedure is fully understood.
