    Anodes

    Wheels I have worked on a number of vessels with an Impressed cathodic protection system - none used zinc anodes,think it might have been graphite mixed with something else.
  2. if mixing small quantities try a few avo syringes.
  3. 700lumens what about 4100lumens http://www.wickedlasers.com/torch or http://www.reactual.com/outdoor-equipment-2/led-lights/brightest-led-lights.html for one with 7500lumens
  4. Perhaps Weiti river has a lower salt content than Tamaki river?
  5. Apologies everyone - hit page down. Rehab. I take it Was aimed at me. My understanding for email via HF is that you need a modem that works with the SSB – and a shore provider that operates the receiving HF gear. How much for the HF modem - another bit of kit. I have heard of yahoo and gmail – but as far as I know they do not have HF stations. Please post details for the sat phones with free email. Provided they are in range Why bother with pre programming half a dozen boats in when a DSC distress call is automatically an all ships call Ships are required to have
  6. Part of my job has required a fair bit of rule study recently. Still learning....
  7. Gotta say resiliently mounting the generator would be worth doing if not already done.
  8. I keep seeing the mention of email so when I saw in a recent post the one touch email had an * I looked it up So it is not part of the DSC system -You have to have an email provider and a modem Apologies for thread drift - I spent a number of years working in areas where vhf DSC was supported - it was a complete pain in the proverbial - only one genuine distress call and the voice mayday call on VHF 16 came through first, it was not until I turned the ship around and steamed towards the vessel (~40nm away) that the VHF DSC alarmed. When at anchor the OOW on watch or duty AB
  9. The Col regs In NZ Part 22 sorry did not paste well but go to http://maritimenz.govt.nz/Rules/Rule-documents/Part22-maritime-rule.pdf page 29 of 34
  10. NZ does have DSC coverage - but not for VHF or the 2MHz band
  11. As stated earlier: Some AIS PLB/MOB devices have VHF DSC capability as well - this is the alerting function that is req under GMDSS Also not all AIS units (fitted on vessels) will recognize AIS PLBs as an emergency device or at all - so your onboard AIS unit may not alarm when it receives data from a PLB / MOB device or even display a target. Also some onboard units will not display virtual AIS AtoNs. One brand of transmitter that many Garmin devices will not pick up is Vesper. Garmin hope to have a fix in about 12months last I heard. So if buying AIS PLB's make sure your onboard AIS
  12. The LED lights are great and batts seem to last for ages - someone had a light with built in PV cell in it. BUT tend to agree that having wired lights is easier. I never got round to having a socket/charger below for stowing the light. Has anyone considered using fibre optic cabling rather than electrical. Thanks Beccara - misread your earlier post...
  13. No maximum distance. Minimum distance 1 metre Agree with your plan Scottie - Sailing - side lights and stern light Motoring - side lights and all round white light anchoring - all round white light. If wanting to avoid running wiring to the masthead your could fit a steaming light low down on the mast and just hang an anchor light when needed. I made a fitting years back where the battery powered anchor light clipped in to a fitting on the front of the mast - turning it into a steaming light. Beccara - Can you clarify what lights you have on when motoring?
  14. Did you get any info from that guy I put you in contact with?
  15. Good Luck Wheels! Let me know when you get close to Tauranga. If entering on an ebb tide go wide on Tanea and keep an ear out on VHF12 for shipping movements.
  16. In the words of Larry Robbins - It is called impact hydrography. He told me that on a run to the Riverhead Pub..... on a steam launch.

    Splicing 8 plait

    That was part of the old chaff gear from a towline - yeap just the right size for heaving lines once puled apart

    Splicing 8 plait

    With splicing a used towline have used dish washing liquid. Makes it easier to splice hands end up clean part of the towline gets cleaned

    Splicing 8 plait

    Is it old or new? In old rope that is hard to splice I have used a manrope knot splice, bulky but short Are you using the correct splice for the exact product? There maybe a diff splice?
  20. Not sure if many on the site knew him but Young Ron passed away last week. Ron had been a volunteer with The Spirit of Adventure Trust from the early days. A volunteer with the maritime museum in Auckland - He helped with the construction of the Ted Ashby and crewed on several of their vessels. He crewed on Viking with Con Thode and Sir Gorden Tait on their circumnavigation of NZ. Enjoy your rum and orange - you deserve it.
  21. Errors can creep in: - The antenna position. example - a 266m long ship with antenna aft above the bridge, but setup has it positioned on the bow. A 200m error in one case. - Some older GPS units do not communicate well with early UAIS units - your main nav GPS on a datum other than WGS-84, - quarter nm error on one occasion. - Manual offset on main nav GPS - error witnessed by this one was +10nm... With Class A they have to take a feed from the main GPS - they also have their own built in GPS but the external feed overides the built in one. I think the USCG highlighted the issues w
  22. Point taken on the non magnetron radars. The point I was trying to make was do not rely on a ship's radar set to pick you up - the majority currently have magnetrons. Also from personal observation of hundreds of different ships, and who knows how many radar setups I have found a large number are poorly setup.
