FPB 64 #5 Topped Out – #7 Construction Starts

FPB64 567 Aug Sept6 11 100 We have been behind in our reports on how the FPB 64 production is progressing. This batch of photos were taken during August and the first week of September. The lead photo is, in construction industry parlance, the “topping out” of FPB 64-5. The jig built roof structure is being lowered over the window mullions. Very precise construction is required for these elements to fit together. FPB64 567 Aug Sept6 11 101 Looking forward from the aft side of the house. FPB64 567 Aug Sept6 11 102 The great room roof is heavily reinforced. Note the transverse girders which tie to the mullions. FPB64 567 Aug Sept6 11 103 All of this structure depends on the stiffness of the window mullions. The mullions are connected at the top of the coamings (a box beam), at the deck, and to a heavy topside girder. The “couple” between the topside girder and coaming top makes for a hugely stiff mullion connection. FPB64 567 Aug Sept6 11 104 House roof structure welding now almost complete. FPB64 567 Aug Sept6 11 105 Jumping below the waterline, a few s keg details, starting with this very complex shape on a skeg plate section. FPB64 567 Aug Sept6 11 106 The skeg framing on FPB 64-6. Between the heavy framing and 12mm plate, this is designed for abuse. FPB64 567 Aug Sept6 11 107 Note the massivee casting that is welded into and projects aft, beyond the prop tip, from the bottom of the skeg. FPB64 567 Aug Sept6 11 109 Still on #6, a series on the bow reenforcement. The stem bar (centerline girder) is stiffened with horizontal frames. FPB64 567 Aug Sept6 11 111 This area is sealed off with a collision bulkhead forming the forward bulkead of the chain locker. The round bar is the towing bit/Sampson post above deck, is solid, and welded at three horizontal locations. FPB64 567 Aug Sept6 11 112 Switching back to FPB64-5. FPB64 567 Aug Sept6 11 114 A nicely faired thruster pipe. FPB64 567 Aug Sept6 11 115 Strapping and notched frame (reinforced of course) for plumbing and wiring runs. FPB64 567 Aug Sept6 11 116 Looking into a coffer dam, the separation between fuel and water tanks. The lid with its access hatches is ready for welding in place. FPB64 567 Aug Sept6 11 117 Preparation for transducers in the forepeak. FPB64 567 Aug Sept6 11 118 A Dorade box before the top is welded in place. The down pipe with lid ┬áis at the top of the photo. FPB64 567 Aug Sept6 11 119 Same pipe, from inside, looking up. Note the gasket (black) to seal the lid. FPB64 567 Aug Sept6 11 120 The stabilizer insert reinforcement. FPB64 567 Aug Sept6 11 121 Same area, now with the 12mm (15/32″) hull plating in place. FPB64 567 Aug Sept6 11 122 All of which resides in a watertight coffer dam. FPB64 567 Aug Sept6 11 123 The lid of which is here closed. FPB64 567 Aug Sept6 11 124 The aft end of the great room . Note the penetration at the top for mast wiring, of which there is a lot! This opens into a locker under the stairs (new in the second series of FPB64s) which keeps it dry. FPB64 567 Aug Sept6 11 125 Inside of transom on #6. Hard spots are for various exhausts. FPB64 567 Aug Sept6 11 126 Aft end engine room, showing centerline reinforcement, which terminates at the rudder post. The top of the rudder shaft pipe is well above the waterline, so no packing gland is required and there are never any leaks. FPB64 567 Aug Sept6 11 128 A day tank in the engine room. FPB64 567 Aug Sept6 11 108 And finally, the cabinet work for FPB 64 -7 has started. This is a hatch coaming.

    Steve – have you considered the gyro type stabilizers? such as seakeeper? http://www.seakeeper.com may decrease construction costs and decrease drag, no external stablizers. keep those updates coming – :) kindest,

    Hi Wolff: We have discussed gyros before. For our type of use at present they are not well suited.
