    B&G autopilot confusion

    Ok - I will be making the jump to the H5000 Hercules with the H5000 pilot.

    Nexus NX systems

    My Nexus HPC compass died this year so I replaced it with a B&G Precision 9 Compass on the N2K bus. Heading is passed via the GND10 to the server. Unfortunately, the roll and pitch data is NOT passed by the GND10 from N2K to RS485. This means the Nexus server is no longer getting that info for doing the advanced wind calculations. The reason for two compasses you have now is for the server take advantage of roll and pitch only available on the Nexus compass, even though the Evo compass is better. It is normal to read SOG and COG random numbers when docked. Do they display data when the boat is moving? If not, it sounds like you need to get into the source menu and make sure that the source has been selected for the GNX120 displays. --------------------- Different but related topic - I have decided to jump from the Nexus server based system to a B&G H5000 Hercules based system since it is getting more difficult to keep the Nexus stuff working the way it should be. This fall after the boat is hauled, I'll be pulling off most of the Nexus gear and selling it, once I'm sure I have all the B&G bits working. The list of items that will be available for sale is as follows: (2) Multi Control Displays with covers - one has two left buttons inoperative (Set and + buttons) - can probably be fixed by opening the case, also can be controlled repotely (1) Wind Data Display (3) XL Multi Remote Displays with covers and Carbon Mast Bracket (1) NX2 FDX Server (1) Nexus HPC Compass - has noisy drivers causing bus problems and erratic wind data. Someone may be able to fix this or use for parts This isn't a "For Sale" ad yet - just a note to let those who might be interested that it will become available this winter.

    yanmar rebuild?

    That was me and still on my old blog - my rebuild was based on clogged cooling passages on a raw water cooled engine. Didn't need to do rings and valves because compression was good and it didn't use oil. Yes I would do it again. I sold the boat in 2013 and now have a J/109 with a fresh water cooled 3YM30. I don't expect to have the same cooling issues with this engine. The manuals are available on the J/30 site for the Yanmar 2 series and J/109 site for the 3 series.
  4. Moonduster - great comments. I had a pretty reliable setup with good sensor data working with the Nexus server. The wind instrument was originally an analog input to the Nexus server. When the sensor died after 12 years, Garmin had taken over Nexus and replaced the analog output wind sensor with a sensor that connected to the Nexus RS-485 bus. Garmin also introduced the GND10 that translates between the Nexus RS485 bus and NMEA2000. The wind data previously had correction for pitch and upwash using the Nexus server, so was pretty good and I took the time to calibrate it. Bottom line - I had good data and feel as if I've stepped backwards since I had to replace a good compass that is now no longer available. Rather than continuing to throw $ at trying to keep the old system working, I figured it was time to start making the switch. The problem was when the Nexus HPC Compass died, I couldn't get a replacement and decided to use the B&G Precision 9 compass. I thought it would be a good replacement, then after it was installed I found out that the GND10 did not convert roll and pitch from the N2K side to the RS-485 side. Thus all my true wind data is now less accurate than before. I have an Actisense NGT-1 and NGW-1 that I can use to check the N2K bus load and data. I plan to do some tests to find out what the data rate is for wind coming through the Garmin GND10. If it is marginal, I was thinking of getting a Raspberry Pi and programming it so it would be dedicated to converting the RS485 wind data to N2K sentences that contained apparent wind speed and angle at a minimum 5 hz update rate. I think this could work and if not, I can always add the B&G MHU sensor which is very pricey! The H5000 should be able to do the advanced wind corrections assuming the N2K wind data input is accurate and at a fast enough rate. My analog speed input is pretty accurate. I moved the sensor to the centerline and have calibrated it. I put in a blanking plug everytime I leave the boat, so have zero issues with a fouled paddlewheel. The speed through the water data is very good. I planned on using the analog output to directly feed one of the H5000 analog inputs. For the autopilot, I wanted something that will help performance on the short handed races, and making delivery and cruising easier. My Raymarine S1G is "ok" but could be better. I also really like the user interface on the B&G Zeus to easily control the B&G autopilot. On the other stuff - My sail inventory is pretty good. I have new 3Di main and jib and a new spinnaker used for OD racing. The PHRF sails are pretty good too. I'm fortunate to have worked with the local North loft on testing new sail designs and have access to some pretty good stuff. I'm retired so tend to spend my time doing boat projects on my own boat and for friends (e.g. the photo in my original post was work I did on a friends boat). As a retired EE I can handle most of the electronics integration work and can write some software... if the vendors would just open it up so we could fix their mistakes! I have the ability to design, install, integrate and test the various systems and enjoy doing it. Thus the cost to me is the equipment as my labor is "free". I'm fortunate to have built a good reliable crew over the past few years with some who should be able to help with the next level. So - assuming I get good wind data....back to the original questions - any experience with the H5000 Graphic Display versus the Triton 2 displays?
  5. I've posted a number of times with stuff I've done to integrate the Nexus FDX server the previous owner installed in 2005 with the J/109 I purchased in 2013. It has 3 XL mast displays, on the spray hood 2 Mutli controls and the Nexus Wind display. When the original Nexus nWind Race xducer died I installed the Garmin gWind race replacement with GND10, which gave some NMEA 2000 connectivity between the Nexus Server and the N2K side. This summer my Nexus HPC compass died and I replaced it with a B&G Precision 9 on the N2K bus. Unfortunately, the GND10 does not translate the roll and pitch from the N2K side back to the Nexus bus side, so all the advanced calculations done by the Nexus server no longer work. I posted a while back on the J/109 forum with some interconnection diagrams. The diagram is slightly behind what I have now, but gives a pretty good idea on the starting point. Here is the grand plan I am considering this winter: Nexus XL Mast Displays (3) - Leave in place and drive from GND10 for Magnetic Heading, COG (Bottom), TWA & TWS (center), Boat Speed, SOG (Top). Long term replace with N2k compatible displays. I can control the displays for any infrequent settings changes via a laptop connected to the GND10 rather than using a Nexus Multi Control. Spray Hood Nexus Multi Control (2), Nexus Wind, B&G T41 Triton - Replace the 3 Nexus displays with B&G Triton 2 and keep the B&G T41 Triton. One Nexus Multi Control has buttons that are intermittent when pressed so I need to do something to replace it. Since I extended N2K bus to spray hood it is a no brainer to plug in additional N2k based displays. A piece of White Starboard cut with the new holes for the display mounting is what I did in the past and will be done again. Possibly add B&G H5000 Graphics display and B&G pilot control (see 6 below) Question... What does the H5000 Graphics display have that the Triton 2 does not? If no additional features and I can take advantage of unique H5000 Hercules data on the display, I may just use the Triton 2s as I run out of real estate using the larger H5000 Graphic display. Nexus Server - Replace with B&G H5000 Hercules. Connect existing analog paddlewheel to the H5000. Replace analog depth with NMEA 2000 compatible depth transducer unless there is another way to easily get the Nexus (Airmar) depth xducer to play with the rest of the system. Some of the chart plotters will drive the analog xdcer so I need to do more research. The Garmin gWind Race and GND10 will feed wind data via N2k to the H5000. I already have a B&G Precision 9 compass on the N2K bus for heading. Helm Pedestal Mounted Raymarine e125 - Could keep this if I keep the existing Raymarine S1G autohelm for integrated control. Otherwise would get a B&G Zeus 3 12". Nav Station Raymarine e97, Surface Pro 4 running OpenCPN connected to N2kBus via Actisense Converter - All this would be kept. Raymarine S1G Autopilot with Remote - Potentially replace with B&G H5000 Pilot Computer, H5000 Pilot Controller on Spray Hood, RF25N rudder sensor (replaces Raymarine analog sensor). Would use existing Raymarine linear drive - I know it works well with B&G NAC-3 so should work with H5000 pilot computer. If I updated to the B&G Autopilot, I would definitely put a Zeus 3 at the helm for easy control there. I have a router and ethernet network that any stuff on the install can connect to (e.g. the H5000 Hercules, Zeus 3, etc.). It provides local IP connectivity and when I activate the hot spot, provides Internet connectivity. The intended use is as follows with estimated percentage of use: J/109 One Design racing - 15% Beer can racing - 40% Double handed racing - 10% Distance racing - 15% Deliveries & Cruising - 20% I'm interested in comments on the setup and what might not work well or might work better. Question... What calculations/features are available without the H5000 Hercules on the Triton 2 and Zeus 3? (e.g. what do I loose if I don't jump to the H5000 Hercules processor) Below are pictures I took of an install I did on the spray hood of a friends J/109. This is all B&G Triton 2 stuff without an H5000 Processor. It also has the Triton 2 Pilot Controller and NAC-3 pilot computer. There is a Zeus 3 at the helm. Based on sea trial results, I really like the setup!

    B&G autopilot confusion

    great info gurok! Does anything above Perf Level 1 require the H5000 processor, or are there some things that can be done without it? I was thinking of doing an incremental approach for processing where I had Expedition do the performance processing on a PC as I transition off the Nexus Server, eventually to an H5000 Hercules processor.

    B&G autopilot confusion

    Resurrecting this thread. I was looking at the B&G website and course computer documentation. I can see the NAC-3 course computer is designed to handle greater loads than the NAC-2. Are the algorithms the same for the various steering modes and being able to set system response? I also see the H5000 pilot controller but didn't find any difference with the NAC-3 via the online manuals for it. Is it the same as the NAC-3? The install documentation and pictures look the same except for the model number marking on the cover. I just installed on a friends J/109 the Zeus3 12", a number of Triton 2 displays and the Triton 2 Pilot remote on the spray hood with the Precision 9 compass, NAC-3 course computer and RF25N rudder sensor. The old Raymarine linear drive was used without any problem - clutch and motor leads easily interfaced with the connections on the NAC-3. Integration and setup were pretty straight forward. Did initial sea trial under power (no sailing yet) and am very impressed with how easy the system is to use. I really like the controls on the Zeus 3 where you can turn the knob to steer the boat, or use the push button like display that replicates the pilot remote control. I'm considering updating the old Raymarine S1G on my J/109 with the B&G setup and want to know if I should consider the H5000 pilot rather than the Triton 2 setup with the NAC-3. I do some single and double handed races in addition to occasional deliveries. Who has experience with the H5000, NAC-3 and NAC-2 course computers? Looking for some feedback on performance and the actual differences. If the algorithms are the same, would the NAC-2 output be sufficient for a J/109 using my existing Raymarine linear drive?
  8. Finally got a reply back using their website contact form. It is now working again so they must have found an IT person on the street corner.
  9. I'm trying to verify sailor classifications for an upcoming regatta. The entrants are required to include their World Sailing Sailor ID so we can verify the status as Group 1 or Group 3. The Search for a Sailor function doesn't appear to be working. I used the contact form on the World Sailing site to report it, but haven't heard anything back. Is it just me, or is anyone else able to get this to work? Are there any other ways to lookup/validate the sailor's classification?

    Nexus NX2 system failure

    I hear ya dacapo. A month back my wind started reading 300 kts and wind angles all over. I suspected it was the gWind Race on top of the mast that I replaced 2 years ago. Bought a replacement and it came in the box with the housing split open and the guts rattling around the box. Called Garmin and got another shipped, and returned the piece parts. Up the mast and installed the replacement gWind Race. Same problem with the wind readings. Started isolating components on the bus by disconnecting them. Thought I fixed it when I disconnected the various components on the bus. Lifted the bus leg with the compass and server and the displays magically cleared up with wind reading good. Aha - thinking I found a bad server, borrowed one from a friend. Still the problem when I hooked up the new server. It was the freakin HPC Compass that was bad. Since the Nexus HPC Compass hasn't been made in over 10 years and is no longer available, I ended up replacing it with a B&G Precision 9 compass on the N2K side of the Garmin GND10. The Garmin folks didn't see fit to pass roll & pitch from the N2K side to the RS485 side so all the good processing to correct calculations that the Nexus Server does just went away. After spending almost 1.5 grand for wind and compass the system is kind of working again.... and I now have a spare wind sensor sitting in my basement that still works, and a system that won't correct for heel angle. I may just bite the bullet and buy Expedition and have it do the processing and corrections. If I do that, the Nexus server can go away. Seems like a more cost effective approach than going to a B&G H5000. As each of the Nexus displays die, I am replacing them with N2K displays (B&G Tritons) so there is a path forward.

    Can you mix instruments and transducers?

    I am also on my 3rd wind sensor. The original Nexus Race transducer made in Sweden lasted 10 years. The replacement Garmin gWind Race xducer made in Taiwan arrived and was defective. Garmin shipped a replacement. It lasted 18 months and just last week started putting out random data for speed and angle. I just received a replacement that I ordered this week. It arrived with the sensor housing split open and the parts rattling around in the box with no visible damage to the shipping box. I am waiting for a response on when the replacement will be shipped. The USB port died on my GND10 after 1 year. Shipped it back to Garmin for a flat rate repair. Overall, I think Garmin has some quality control issues.

    Can you mix instruments and transducers?

    Raymarine ITC-5 from Defender is $235.99 and works well - I've used it with old Raymarine sensors and new B&G equipment. On another install I used the Garmin GST-10 analog speed to N2K converter. It requires a Garmin device (chart plotter or Garmin N2K display) to do initial calibration. Read this thread with the history on how it was done.

    Asymmetrical spin (only) takedown

    +1 ^this^ I do it single handed on my J/109 using the autopilot. Sail deep - almost DDW. Haven't needed to start the engine. The sail is depowered when the tack is released.

    That's an Echomax inflatable radar reflector. It rates pretty highly as a passive reflector and comes with actual test results showing RCS over a swept frequency.

    Cool pic that photographer Steven Cloutier took shortly after the start of the 2017 Ida Lewis Distance Race. We are ducking Temptress. The picture is now used on the front page of the Ida Lewis Distance Race website.
