  1. Sabre - when you say maneuverability how are you trying to swim? On your back or front?
  2. The other week a bunch of folks from work had a go with several different Inflatable Life jackets - I think there were about 10 Life jackets tested - 4 types, 2 of 275N and 2 of 150N First one I tried was my old work one - about +10years old and 18months since last serviced - a 275N one - inflated gently and rolled me onto my back head clear of water, easy to breath, no crotch strap Second one was a 150N jacket - failed to roll me onto my back, if unconscious I would have drowned. No crotch strap, once on my back the jacket just did not feel as comfortable as the 275N one. In every case wh
  3. Would be close to the max range. Camera was eye height of the shortest officer on the bridge. For those that regularly sail in Tauranga harbour the stbd buoys and beacons in the main channel are set 20m outside the channel - straight line between them it gets shallow enough that the tugs will not go there ~5-6m at the last survey. Tanea 2 and 4 are inside the channel by ~ 10m, but from the buoys to the 5m contour is ~45m at No2 and ~25m at No4 depending upon the current / wind acting on the buoys. If anyone has questions about the changes to the channels / marks just ask.
  4. Nope here are another few - thought on the cruise ships there are cameras 347m S Class https://youtu.be/_WalknYC8_w Cruise Ship view https://youtu.be/9Rn38XUdJFY
  5. A recent arrival into Tauranga.
  6. Hi Willow, It was great to have the channel clear, I had slowed down as I had been told there was a number of boats in the cut. Have a camera recording fairly often so might have footage. Thanks again
  7. KM - agree it does not sound like Jim. Any comments on the pics below? The pic was taken after the ship took action. There was another small boat that cannot be seen. The yachts racing on Saturday were fantastic at keeping clear - Thanks!!
  8. It directs you to the location of where the incident happened - not to where the tag is now. Has a 50ft range - bluetooth. If you search for key trackers you will find a bunch of similar devices, some with a greater range.
  9. Hi Wheels - 400ft long ship - try 1138ft long - that is the longest vessel type currently calling in NZ waters. The longest container ship is around 400m - 1312ft.
  10. Area near where yacht was I think. Beacons are outside the channel by ~20m.

    Kaikoura Wharf.

    LINZ from what I understand - though the local HM would likely order a survey.
  12. or try something like http://www.supercheapauto.co.nz/Product/ToolPro-Utility-Oil-Pump-1-Litre/384856 Avoids holes in the deck and / or funnels. For small quantity topups I use an 80-100ml syringe.
  13. for what it is worth 1936 - 3.99m - 13ft 1&3/32" 2011 - 4.12m - there was a deep depression coinciding with a spring tide
  14. Here is a bit of text from one report relative to the land.... Looking at that have they looked at the level of mean land level - in other words has the land risen or fallen relative to a vertical datum other than MSL?
  15. On the 5nm off the coast - there is a voluntary code for vessels with oil or other harmful liquid cargo - 5nm - till alteration to make port is required. If you have a plotter showing you out of position check what datum it is on and what datum the electronic charts are in. Also check if some fiddler has put in a manual offset. Also check how many sats the thing is picking up - in some places in the sounds I have found the sat numbers below 4. another point WAAS - designed for North America - apparently it can lead to position error in other places. IMPORTANT!!! check your smoothing funct
  16. fatigue could be considered as well water ingress
  17. Have you looked at janus config log transducers?
  18. Vessel was in ballast being towed to china to get a new fore body fitted to the aft section - probably very little oils onboard. Vessel was built for service on the great lakes in 1978, sank in 2009 - that is old for a bulk carrier. A bulk carrier in ballast under tow in heavy seas.... the vessel had be aground in the past - was due to get the fore section replaced - fatigue, water ingress and so on.
  19. There are hydraulic cutters, but never had them only had gas gear or cut off discs on a big angle grinder - hence my preferred option of paying out the wire, after all if you have a 1200m wire and you cut off 400m you will most likely change it out so why risk people to save a bit of wire.
  20. OK - towing on a bridle with fish / delta plate then pennant to towline. Situation: Not an emergency - Heave in the towline and lock the pennant eye in the forks / sharkjaw / pelicanhook, undo the shackle from towline to pennant, release the pennant. Situation: OH F$%^ - On the old dutch tug we could just dump the brake and the wire would run out. Worked on a couple of boats where the winch was secured on a dog - meaning you had to heave up to remove the dog then you could dump the gear. - If you could control the position of the wire - you could take the chance the pennant / stretche
  21. Yeap - did use one on doors a bit like those, had to adjust the gates
  22. Have said it before - Resene did hire them - I-strip speed heater.
  23. Nearest Navtex transmitter is in Asia - there are no stations in NZ or Aus. You need to be in range of a transmitter - say 500nm or less. So unless you are going to be traveling to part of the world that has Navtex I would not bother with the gear, and even then....
  24. you missed one that has been out for years - AIS & DSC VHF in one. http://www.mrtsos.com/products/personal-locator-beacons/smrt-v100 406mhz is the sat freq - have a read here http://www.mrtsos.com/plbs-explained/what-is-a-personal-locator-beacon-plb AIS is not restricted to commercial vessels, Many ports operate ais receivers, not to mention about 80-90% of the coast is covered.
