    Lifting Engine with Boom

    in TechTalk

    Posted

    Get a big friend, or two normal friends to actively balance the boat with their body weight as you swing the boom out over the finger... 

    And put some tarps and polythene down to catch any crap that dribbles out of the engine. Have a few wooden blocks ready to prop the engine up to stop it rolling or turning out of control.

    This seems like good advice.. thanks!

    Going to attempt to remove my engine with the use of a chainblock and the boom.. with the boat in the water.

     

    Swing the boom out over the side and lower onto finger.

     

    Any advice on what/what not to do?

     

    Engine is about 140kg.. I think that included the gearbox.

     

     

    Solar Logging

    I actually think I RaspPi even in mid winter wouldnt kill the batteries as they are kept full by solar easily.

     

    well this is what i set out to proove ????

    yes.. power consumption of the Pi and modem is high.. but I have the shore power most of the time to cover this. 

    Maybe one day I'll try dumb it down to lower the power usage.

    As for the SIM.. 

    2degrees (and some others probably) let you share data among (up to 5) SIMs... I already pay for a sim for a mobile wifi stick thing when I'm travelling,so it costs no extra to share it with the boat

    Epever MPPT solar controller, RS485 connection from that to an onboard raspberry pi, which polls the data and logs it to a database.

     

    4G router to access it all.

    Software is

    Grafana to make the graphs

    Node-Red to poll the solar controller and push to database

    InfluxDB for storing timestamps and values.

     

    been fiddling with this for a while now. Today I've got it updated to show total AH in per day. 

    Integrating Raymarine auto pilot/B&G wind gear

    in TechTalk

    You can tell the Zeus which nmea 0183 sentences to produce, so provided you know what's required you should be able to produce it....

    It was a while ago since I did this, but I seem to remember that you could turn specific ones off, but that you could only choose from the list, and they didnt include the older version of wind sentence. I think they were all enabled by default.

    The AP you have has an nmea0183 output, so it can go directly into the Zeus nmea0183 input port, and vice versa.

     

    Caveat with this - I tried on the ST2000, but the Zeus 0183 uses a different (incompatible) 0183 sentence for wind data to the raymarine gear, and so althought they both talked 0183, I could not get the AP to steer to wind without some kind of additional conversion.

    Catamaran training

    in MarineTalk

    Posted

    I'm looking for someone with a Cat  30-50ft to take me sailing (not racing) for a day or two.

     

    I have experience on monos, but bugger all in a cat..

     

    I've signed on to skipper a charter in Europe later this year in a Cat and need to do a bit of sailing and manoeuvring under power beforehand.

     

     

    Happy to pay my way... anyone got any suggestions?

    Offshore Medical Course

    Thank you Razz, Fish and others for your support.

     

    Steve Pope as to your comments - ".. it is surely a commercial venture."

     

    Actually -you are quite wrong.

     

    I do this to help NZ yachties and do NOT get paid to do so. I do it because I enjoy it, because I was asked to do it and I want to give something back to yachting.

    It also enables all of the volunteers (there are many of us - Sally, Bek, Jenny, Angus and I) to donate money to a yachting charity.

     

    All of the profits are donated to charity. 

     

    I was paid to rewrite the YNZ Medical requirements -  I donated this money to Youth Sailing.

     

    Profits from the first "Dr Dave course" - were donated to Cyclone relief in Fiji

     

    All of the other course profits were donated to Disabled sailing.

     

    Firstly we outfitted a boat for a disabled race officer to help her get in and out of the boat.

     

    Last years profits are going to buy Defibrillators for patrol boats and the RAYC for cardiac arrests.

     

    We are also putting money towards building a yacht to teach disabled sailors how to sail

     

     

     

    I suggest prior to making ill-informed comments - you find out the facts

    Legend. Thank you Dr.

    Rigging Inspection & Insurance

    in MarineTalk

    Posted

    We get it checked every year regardless. I don’t like the idea of the rig falling down. I dislike the idea of the rig falling down for some stupid reason even more.

    Over the years we have found cracked rigging screws, cracked spreader and a worn shroud thingammy. All of which would have resulted in a catastrophic failure somewhere.

     

    I think that if we service the engine regularly why wouldn’t we service the mast? It’s better insurance that any policy.

    pretty solid logic

    can I ask size of the boat and approx how much an inspection costs?
