    Le Trawler was fitted out last year in the same yard at the same time as our sailing yacht – at the Allures factory in Cherbourg, Northern France. They specialise in aluminium sailing yachts with lifting centreboard designed and fitted out for long distance blue water sailing.
    The guys at the factory were incredibly proud of the finish and level of equipment, and it was a big project for them. It is nice to see it is receiving great reviews. I recall the press couldn’t believe the standard of the rolled aluminium hull without chines – they thought it was GRP.
    The boat headed across last year in mid September in a two week window between boat shows, and were pretty oblivious to the hurricanes of that time!
    (We’re heading across later this year, so will be working our way up the east coast next spring headed for the Northwest passage later that season. Hopefully catch up with a few Panbo-ers then)

    Ben, why is the orientation of the anchor winch twisted?

  3. Jon Longworth says:

    Looks like it’s aligned with the starboard hawse.

  4. Ben Ellison Ben Ellison says:

    Jon is correct. If you look at the Garcia photo gallery, the GT54 has a ship-style housed anchor on the starboard bow. I’ve never used a rig like that but it looks easy and clean, and I notice in the construction shots that they included chafing ribs. Probably quite noisy, though, and I guess you have to manhandle a second anchor over the rail.
    Wait, come to think of it, I had some drama with a system like this when I worked on a 160-foot oil rig supply boat in about 1973. It generally worked fine, even anchoring in 400 feet plus of water so we could tie stern-to to a deep rig.
    BUT, if it was too calm when we picked up the anchor or anchors the chain could pile up and jam against the deck so a couple of us had to climb into the chain locker and roughly flake it. Damn scary.
    If some idiot in the wheelhouse had accidentally let go the winch clutch, I might have literally come up through the hawse pipe, in small pieces. Also, no one was asleep when we handled anchors.

  5. Ben – I think the diagram left out more than the jumper between hubs… The N2K networks look a little funky to me. Both of them appear to terminate in the “Convertisseur” you mentioned – what kind of device acts as an N2K – 0183 converter, and also terminates multiple N2K networks, while keeping them isolated in conformance with NN3D requirements? I assume the daisy-chaining shown is where the N2K backbone “changes names” to “CANBUS” and then back again… 😉

    Good catch, Grant! The diagram shows the NMEA 2000 backbone daisy chaining four times, each one a no-no. Personally I use daisy chaining on Gizmo, despite NMEA’s ban on it, but I only use it along a drop. I wouldn’t do it in the backbone as shown. I’ve never heard of the N2K “tee” built into those FI-50 displays failing, but still…
    However, are you sure that a Furuno system like this can’t have a single N2K backbone? That’s the way I read it, with termination at the GPS and Compass and an assumed tee at the N2K/0183 converter.

  7. Ben – I’m pretty sure. From the NN3D Installation Guide:
    “You may ONLY connect one MFD or DRS to the same NMEA2000 Network. Some NN3D vessels may contain several smaller NMEA2000 Networks where data from each NMEA2000 network is linked via the High-Bandwidth NN3D Ethernet Network. In these cases, each separate NMEA2000 network will be “Bridged” together via the NN3D Ethernet Network. NN3D MFD and DRS NMEA2000 ports shall also not be connected together. In the case where NMEA2000 engine data, or other ship’s data, is introduced to the NN3D Network, the connection is made to only one MFD, and this MFD will bridge the data to other MFDs in the network.”
    I’m guessing the vessel isn’t wired exactly as depicted on the diagram, otherwise there would probably be some issues….

    I can see a Furuno autopilot display here.
    Do you know what kind of driver unit they use for such a big boat ? ( I can’t find anything that match Raymarine Type 3, and I have Navnet 3D … )

  9. Ben Ellison Ben Ellison says:

    Hi Rolf, I don’t know how the GT54 is set up but Furuno 700 series autopilots can use various size Accu-Steer drives, including an unusual option that enables power steering and “shadow drive”:

  10. Rolf says:

    Thanks Ben, that was new to me !
    It’s actually a sailboat (Regina af Vindö 43) I want to replace a Raymarine-Type-2 long drive unit.
