INSTALLATION
MANUAL
Section 1: MECHANICAL INSTALLATION
1.0 Introduction
This document is intended to give details and guidance to a boat builder or equipment installer to
install the Seakeeper 9. The Seakeeper 9 is capable of producing loads up to 17.09KN (3,842
lbs.) at each of the four mounts and careful consideration should be given to foundation design to
ensure it is capable of transferring 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.
It is assumed that the installer is familiar with installing mechanical fasteners in marine
structures or using high strength adhesives on aluminum and fiberglass (FRP), 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 perform a structural
analysis.
The installer should review the following list of reference drawings to ensure the mechanical
installation procedure is fully understood.
