Section 1: MECHANICAL INSTALLATION
1.3 Preparation of Hull Structure
Refer to Seakeeper Drawing No. 90031, Model 7000A Gyro Installation Details . Important dimensional
and load information is given in this drawing that will impact the design details of the structure that will
receive the gyro as well as selection of adhesive to bond the gyro into the hull.
The foundation “saddles” of the gyro are designed to be bonded directly to the composite hull structure
of the vessel to effectively distribute gyroscopic loads. A complete bond is required between the inside
surface of the saddles and the hull structure. To aid in determining the quantity of adhesive required,
the surface area of Port saddle bond area is 340 in
2
(2194 cm
2
). The starboard saddle bond area is 310
in
2
(2002 cm
2
).
Seakeeper has an optional installation jig available, P/N 90012, that is intended to duplicate the gyro
foundation geometry in order to check clearances and alignment. The jig will allow the builder / installer
to lay-up and adjust the foundation dimensions to create a low-clearance fit between the gyro
foundation saddles and the hull structure. Shear strength of the adhesive will be maximized if the cured
thickness between the vessel structure and gyro saddles is at the thinner end of the adhesive
manufacturers recommended range. Therefore, the jig should be used to confirm that the overall
dimensions of the foundations are square and level and that the adhesive gap is within the adhesive
manufacturer’s maximum recommended thickness. See Figure 3 below.
Note: Do NOT use the installation jig to establish gyro envelope
dimensions. Refer to Drawing No. 90031 for envelope dimensions.
The hull structure supporting the gyro should be installed so the gyro is parallel to the waterplane in the
port/starboard and forward/aft directions.
