The Seakeeper<\/span> 2 can be affixed to the hull structure using two methods 1) Longitudinal Beam Bolt-In installation or 2) Transverse Beam Bolt-In installation. Neither option affects the operation of the Seakeeper<\/span>. However, one option might ease the installation process or allow for a larger service envelope. Depending on the structure to which the Seakeeper<\/span> is fastened, blind threaded holes or thru-bolting can be utilized.

Refer to Seakeeper<\/span> Drawing No. 90487 \u2013 Seakeeper<\/span> 2 Installation Details \u2013 Bolt in Method. Important dimensional and load information is given in this drawing that will impact the design details of the structure that will receive the Seakeeper<\/span>. It is assumed that a proper structural analysis has been performed for the hull structure to which the Seakeeper<\/span> will be fastened to ensure proper strength margins for the loads the Seakeeper<\/span> will create during operation.

The hull structure supporting the Seakeeper<\/span> should be installed so the Seakeeper<\/span> is parallel to the waterline. In addition, the four areas on top of the beams on which the feet of the Seakeeper<\/span> foundation and isolation gaskets will rest, need to be co-planar within .06 in. (1.5 mm) to minimize potential distortion of Seakeeper<\/span> support frame when installed. The isolation gaskets are only used on dissimilar metal to metal contacts.<\/span><\/p>\n\n\n\n

Seakeeper<\/span> offers an optional installation template kit, P\/N 90473, which contains four plates that mimic the mating surfaces of the four feet located on the Seakeeper<\/span>\u2019s foundation. These plates have 4 holes located at the same centers as the mounting holes on the Seakeeper<\/span>. The fixture locates the hole patterns at the proper spacing both in the forward-aft direction and the port-starboard direction. See Figure 5 below. Once assembled, the fixture can be used to check clearances and alignment of the hull structure.

Note: Do NOT use the installation fixture to establish the Seakeeper<\/span> envelope dimensions. Refer to Drawing No. 90487 \u2013 Seakeeper<\/span> 2 Bolt-In Installation Details, for envelope dimensions. A 3-D model of the Seakeeper<\/span> is available on the Seakeeper<\/span> website (www.seakeeper.com<\/a>) to aid in designing the Seakeeper<\/span> foundation and the space around the Seakeeper<\/span>.<\/strong><\/p>\n\n\n\n

NOTE: MAKE SURE NO OBSTRUCTIONS FROM THE HULL STRUCTURE CAN BE SEEN WITHIN THE INSIDE OF THE INSTALLATION TEMPLATE KIT (INSIDE THE MARKED RED LINES). REFERENCE SEAKEEPER DRAWING NO. 90487 \u2013 SEAKEEPER 2 BOLT-IN INSTALLATION DETAILS.<\/p>\n\n\n\n
