General Overview
Type of Yacht:
  • Vessel construction is in accordance with the existing rules of the American Bureau of Shipping’s (ABS) XA1 Yachting Service – AMS designation (hull & machinery) and the vessel is built to the UK’s Maritime Coastguard Agency’s (MCA) Large Yacht Code (LY2), with unrestricted vessel operating area (i.e., more than 150 nautical miles from a port or safe haven), as administered by the Cayman Islands Shipping Registry with a surveyor’s inspection.


  • The following specifications for the vessel are not warranties and should not be construed as an expressed or implied warranty, including implied warranty of fitness for a particular purpose or marketability. The warranties offered are contained exclusively in the Construction Contract and Security Agreement warrantied by Christensen Shipyards.


General Construction


  • FRP parts are constructed to detailed laminate schedules, using resins and glass reinforcement. Builder shall achieve the highest fiberglass content by using steel rollers or squeegees. Builder to use large molds, integrating decks, coamings and transverse members to minimize secondary bonding.
  • Vacuum Infused Molding is used in place of hand lay up. Vacuum Infused Molding draws special low viscosity resin into dry fibers using a vacuum induced by a pump. The process compacts fibers much tighter and stiffer than laminates with more evenly distributed resin concentrations. Parts are kept under vacuum until curing resulting in a flat and/or fair surface.


  • The entire hull bottom is a molded PVC sandwich core designed structure, with (1) layer of core sandwiched between solid fiberglass laminates, integrated into which are longitudinal channel stringers. Keel, stem, chine and spray knocker sections are reinforced. Both longitudinal and transverse frames are vacuum infused or hand laid structural foam core material with fiberglass outer skins spaced and sized to provide optimum structural support and rigidity. Web frames are structural foam cored sandwich laminated with fiberglass to the hull sides, and transverse frames have limber holes for access and piping runs as required.




  • The cabin sides, front and back are 5# PVC foam cored sandwich FRP structure.The bridge deck and fly bridge deck are infused 5# PVC foam cored sandwich FRP structure, reinforced with fiberglass hat section beams. Superstructure sections are laminated to deck structure to form a structurally integrated assembly, which conforms to classification requirements.


Hard Top / Mast:


  • The hardtop is constructed from FRP (fiberglass) / mast and the upright supports are constructed from Aluminum.



Bottom Paint:


  • Bottom paint is two coats of anti-fouling paint International, Interlux Ultra and applied over two coats of anti-blister epoxy primer. Paint color isblack.


Hull, Top sides & Superstructure:


  • The hull, topsides and superstructure are painted with Awlgrip hi-solids linear polyurethane topcoat over prime coat. Color is Matterhorn White.



Fuel Systems:


  • The fuel oil storage tanks are FRP integral, construction with aluminum baffling and hydro-tested to ABS requirements. The fuel day tanks and aft trim tanks are fabricated from aluminum; formed, welded and hydro-tested to ABS requirements.
  • Fuel storage tanks are filled via fill station connections located on the port and starboard weather decks. Fuel storage tanks, aft trim tanks and the fuel day tanks are connected to an expansion tank, which is then vented to the atmosphere. The fuel vent expansion tank will capture approximately 80 U.S gallons (302.8L) of overflow before it escapes through the vent. Installed low in the tank is an alarm float switch that provides a warning that tanks are full and that fill operations should be stopped or modulated.


  • Either the AC or DC electric fuel transfer pumps may be used for transfer operations. Main engines and gensets draw fuel independently from the day tanks through the separate fuel service manifolds.
