FPB 64 Update #19


Welcome to progress report #19.We’ll start with a sure sign that we are in the 21st century. The opening photo shows the start of the NMEA 2000 “backbone” which we are installing in the FPB64s.

This robust interface allows us to monitor engine, electronics, pumps, and a host of other functions on easily programmed interfaces. We’ll have lots more on this as we get closer to launching.


There is a large hi definition TV in the salon (standard on all boats). This shows the mechanism (with a faux screen) in the stored position.


This resides on the starboard side of the salon.


The privacy door between salon and forward cabin is shown here. There is a vertical and horizontal closure, which slides to starboard when open.


The same door, now looking from the forward cabin aft.


Speaking of doors, this is the entry into the great room. There is a conventional lockset for everyday use. The dog handles are for securing the door in heavy weather.


Switching to the second boat, which is quickly coming together. The large roll (white) in the center of the great room is the Armaflex insulation.


The timber blocks glued to the hull side are attachment points for furniture and hull panels. The insulation can be seen below the topside stiffener. It will eventually cover almost the entire interior of living area, providing insulation, condensation protection, and noise suppression.


We’ve been working on efficient and reliable fridge systems for 30+ years. The package developed for the FPB83 is the best yet, and it is being replicated on the FPB 64s. These are the three compressors, for the fridge and two freezers. They have “keel coolers” immersed in an integral fresh water tank. No through hulls or salt water to create maintenance issues. The off white colored tank to the right is a back up drinking water supply, operated with a hand pump at the galley sink.


The other part of the refrigeration equation shown above, stainless liners for the inside of the heavily insulated boxes.


The mast assembly is standing up on FPB64 #1. The spreaders are now attached.


View from the side, with the awning frame in place.


The awning frame is designed to allow a strong, simple, and effective covering of the flying bridge. When venturing into areas where extreme weather is a risk the awning can be easily removed and stowed.


The arched shape is designed to shed water. Platforms for two radars are just above the awning frame. The flat between the two pipes at the top is for a Satcom or SatTV dome. The hoop to which nav lights are fixed is not yet fitted.

    ist the architecture of the electical systems in the FPB 64 designs still a “conventional” i.e analog system or are you installing already bus systems to control functions and equipment?
    Thanks for the very interesting reports about the design and progress of these boats.

    Best regards,

    Hi Rainer:
    We are using an analog (traditional) distribution system. The newer remote control digital systems are too new for our type of service.

    Have you considered a Dutch door for the entry into the great room?

  4. Steve Dashew Says:

    The entry door has to be able to deal with substantial hydrostatic pressure in a knockdown, and while this is theoretically possible with a double door, it would substantially increase the weight.
    We have found with Wind Horse (FPB83) that we can leave the door open at sea 99% of the time, if desired, and stay dry inside,so paying the weight and complexity penalties for a double door do not seem like a good tradeoff.

    Hi Steve

    2 questions:
    What is your view of ceramic paint such as Mascoat to supplement your insulation?

    Is there any concern that your wooden nailers could be an entry point for water?


  6. Steve Dashew Says:

    Hello Casey:
    We have not had any problems to date with the timber fastened to the aluminum to which the interior is affixed. Regarding additional insulation, what we have now works quite well. On Wind Horse we have spent time in Greenland, Svalbard, and Alaska without condensation problems.
