  1. Just got a letter explaining the NRC continued failed attempts to eradicate Fan Worm in Opua, and that they are going to have another go. If you can't eradicate in the fully enclosed, clear water Marina at Marsden Cove, what are they using to justify continuing in the murky open waters of the Bay of Islands. I guess its not their money so there is no limit. Watched the effort in English bay, 6 on board I think, all getting paid, big boat too, you couldn't see 1 foot below the surface.
  2. The government makes all sorts of regulations, doesn't mean we have to agree with them, nor does it mean they are correct or fit for purpose. You have led a very sheltered life if you believe governments get it right all the time. A number of people here are expressing an opinion with some good reasons, the outfits you are referring to are not asking for submissions on upcoming reviews from the public and we have been given aback door to the process. The offshore passage rescues of late I have heard about have all been yachts with cat 1. Have not heard of any foreign cruisers coming to grief

    You can go sailing on your computer now, virtual reality goggles and all. No inspections, qualifications entry fees ... No rescues , maybe these rule pushers are onto something getting people out of boats and off the water.
  4. Black Panthers talking about making cat 1 for cruisers optional, nothing to do with what your on about, maybe if you calmed down a bit and read the posts before yelling you might make some relevant responses.

    I don't think its really about grown adults being allowed to make decisions for them selves, more a case of a grown adult being able to make a decision for them self but not allowing any one else to do the same.
  6. I have made a few of these in the past, some pretty complex, some just a pipe into an elbow. You definitely want to inject the water further back, it needs to be well mixed (the arrangement is referred to as a mixer in some documents) before it hits the hose. Inserting the tube into your first elbow after the flange and pointing down the pipe a couple of inches would be good, pays to have something to encourage the mixing, maybe even a solid bar the water hits just after injection. If you have room you could add a length of pipe to what you have made, cut your tube off back to the elbow and

    Read the first line again, its dead on topic and should be copied to the YNZ Race Regulations Cat1-Cat5; Anomalies and concerns thread too. The more that YNZ gets pointed out to them the dissatisfaction and over bearing nature of the Cat 1 regime the better.
  8. Cna someone confirm if this forum is still an avenue to raise points with YNZ about the safety regulation?
  9. Thank you, I do understand the different types of corrosion. I think you may have finally realised my point about paint being an isolator. As to stray currents, if you have them and then bond an otherwise isolated prop / shaft or anything else to the item that is then immersed it is not going to be good. Get rid of the stray current, don't go and pass it through an otherwise innocent part. I would like your opinion on what to do when you have an isolated shaft / propellor with one anode that is obviously overprotected, the current i.e.induced by the anode is way more than needed. I think
  10. Worth a read: https://www.westmarine.com/WestAdvisor/Marine-Grounding-Systems Bonding everything together not always a good idea, can help deal with stray electrical currents but you are better off eliminating them.
  11. Electrolysis is already happening, flowing THROUGH THE WATER, that’s what it is. Bonding makes everything sit at the same voltage, like a battery with all the negative plates removed. No current will flow. So if I bond everything together I wont need an anode because everything sits at the same voltage? Not a very good explanation me thinks. In order to have electrolysis you need an anode a cathode and an electrolyte, if you remove one (think insulation) you dont get a battery. If you have no battery and add a zinc you will have a battery With out proper testing, we continue to sp
  12. That's what we need, more bureaucrats and enforcement officers running round telling us what to do all day issuing fines and notices, all boaties should be licenced and have to receive permission before embarking on any passage, it's a wonder the government hadn't got the process underway already.
  13. Wiring the two coupling halves together can work however it will tend to cause any currents present to flow through your gearbox bearings which is can be a bit of a problem. Pretty sure painting a zinc will stop it working, try making a battery with the anode and/or cathode sealed with paint. Think of it as preventing contact with the electrolyte. With out proper testing, I am quite happy to speculate on what was happening.
  14. Did the Anode last longer with the grounded shaft? My shaft isn't grounded, I painted my shaft and prop put a new anode on and got problems, the paint blistered off, the anode disappeared real quick and I got Oysters growing on the shaft and prop. Bit of research led to the conclusion I was over protected, these were all the classic signs. I left the anode off and all is now happy, the anode actually made a very nice battery and caused more trouble than it solved. Two boat builders I spoke to at the time also suggested leaving the anode off. I was a bit nervous initially but a year later, wit
  15. Why? you want to create a circuit to get the electrolysis going? If you haven't got electrolysis don't touch it.
  16. Some good Ravens turn up on TradeMe fairly frequently, pretty cheap and very seaworthy. Often had quite a bit of refurbishment done due to age, would be wary of one that needed work though, wait for one that the moneys been spent on all-ready.
  17. "the rules are simple to learn and simple to observe and implement." surprised no one else jumped on this one, never been to a yacht club after a race either?
  18. "enjoying a quiet sail" you gave up that right when you went sailing in Auckland
  19. How do you guys cope with the drive from home to your boat? Just remember, in Auckland according to the council housing people, regulations are just a guide - open to negotiation and interpretation depending on your circumstances.
  20. Spent quite a few afternoons sailing round Bream Bay while the F50 SailGP cats were being trialed. Waste of time trying to get close to them, just have to hang around and hope they will swing by. Got buzzed a few times, wish they came closer too, was some of the most thrilling stuff I've seen on the water, when one of them is coming straight at you at 40+knots its pretty awesome. By the time they got to Team USA and AUS they had them pretty dialed in and were happy to come closer, the early teams looked a bit out of control and kept their distance. Each to their own I guess, I love sailing.
  21. This topic seems to be the most active the forum has had for a long time, and its not even marine related.
  22. I just read through the site rules and couldn't find anything to support your statement, "This is a community of individuals who share a common interest in boating" Correct me if I'm wrong, but I couldn't see anything that said we could only talk about boating stuff, there is some rules about politics, religion and weapons, but otherwise politeness seemed to be the main guideline.
  23. Mast out of boat, standing rigging at NSR for replacements. Mast and boom fittings stripped, cleaned and repaired. Chainplate out for inspection, primer on ready for touchup paint.
  24. Climb up the hill behind you, driveways on the development help. The view is one of the most stunning I've come across in the Bay.
