  1. Not from what has been on trademe lately. Some have been at a real low price. One on there right now for 65K
  2. Now that I have viewed it on a decent screen, I take that comment back. Just wet timber is all. Must have been a solid impact.
  3. Looks to me like the area around the Keel fitting point is rotten.
  4. This is kind of what I am nattering on about. So my understanding is, the Gvt funded a string of sensor Bouy's that run along the Hikurangi and Kermadec Trench. The idea is to give us an early warning of what may be coming toward our shores. The reason is that the edge of the drop off was sounded several years back and what was found shocked the scientific guys. Large areas of the Trench has mud overhangs that can and have slid down the sides of the drop. When these go, they can produce a Mega Tsunami. These types of waves are measured in the many tens of metres in height. This is why my q

    As DoT said and is I may add, the Estate has simply withdrawn those 6 from being reprinted. It's not like they have had existing copies removed from shelves. The author drew cartoons for a magazine in the 1920's and when viewed today, some of the cartoons are pretty bad. The worst I have seen had a caption that suggested taking a Black home to burn on the fire like a log. I cannot remember the exact wording.
  7. So with the huge amount of money that went into the DART Bouy system, why is there not better detailed info of what is coming available. Or is the system not yet up and running??
  8. 8.1 and only 19K deep. Does anyone live on Kermadecs? Evacuation has been called for everyone along the East Coast from BOI down to Whakatane.
  9. Stuff have posted thier news story that makes it sound like many on the East Coast need to evacuate. I think they have simply cut and pasted the warning advisory, if one experiances a shake in which they cannot stand up in. It's worded/put together poorly I feel and could make some panic reading it the way written.
  10. 7.1 magnitude (maybe 7.2 - 7.3) 2.27 AM Centred 100km east of Te Araroa off the coast of New Zealand, at a depth of 94km. Tsunami warning issued. The East Coast of the North Island from CAPE RUNAWAY to TOLAGA BAY. Strong and unusual currents and unpredictable surges near the shore are expected in the following areas. This means a threat to beach, harbour, estuary and small boat activities. The East Coast of the North Island from PORT CHARLES to CAPE RUNAWAY including Tauranga, Whakatane and Opotiki. And from TOLAGA BAY to MAHIA, including Gisborne. As well as GREAT BARRIER
  11. The exhuast pulse work hardens the SST and can cause the stuff to crack and not just on welds. OK, maybe I don't know why exactly then, but I can assure you that SST will corrode under the wrap, but maybe not due to lack of Oxygen perhaps. I just assumed. I had lagged the exhaust pipe on my boat down to the point where the water enters the exhaust. Perhaps Salt air or moisture in the engine room caused it. All the SST now wrap is on my plant and it is at about 400DegC. However, I have never unwrapped one to see if corrosion is an issue. Under test, I was taking the main heating part o
  12. It actually shortens the life of the exhaust pipe. Especially if it is SST, It's a compromise situation, Wrapping the only seriously hot part of the engine makes a huge reduction to heat generated in the engine compartment. This can improve many things. The engine runs cooler and many components around the engine compartment will be cooler. The air being sucked in is cooler and thus you get more power and the fuel delivery components are cooler and the cooler fuel is more dense and thus you get more power. The down side is that lagging the exhaust means more heat in the pipe and lack of ox
  13. 6.30PM I think it was. Rescue services went out to look but could not find them around Waiheke. I can understand a wrong LL number putting them in the wrong position. Making that mistake not so much. But draw a straight line through Coromandle to Whangarei puts the line close to Waiheke. So a wrong number could well place one further north.
  14. In fact on thinking about it, the other boats speed may have been 24kts. That would make sense with time. I remember he was about 4 times faster than me. So I would be around 6kts, thus 24kts for him. Looking up the specs, those boats had twin cummins 150Hp engines. Fuel consumption is 7.5Gal/hr. US gall is 3.8lts, so 7.5 x 3.8 x 2 = 57ltrs per hr x 2hrs = 114ltrs My boat 10ltrs an hr for 8 to 10hrs =80 to 100ltrs. Hmmmm, maybe I didn't work that out in my head perfectly, but 100 to 114 is not a hell of a lot of difference and as I said, the numbers are fuzzy now and he may not have been
  15. It was a long time back and the exact figures would be a bit fuzzy now. I may have the 27kts part wrong. His was a Bayliner 3388. Mine has the Perkins 6.354 engine. Usual consumption was around 10lt/hr if I remained conservative with speed. But that figure would climb fast if I pushed it.
  16. When a big Launch would go buy, I used to scoff at how much fuel he would likely be using and how little I would be. Then one day I went for a ride on a mates big launch. We covered the ground at 27kts and went way out to D'Urville where I showed him around. Then all the way back to the Sounds again. I calculated in my head the amount of fuel he used to what I would have used. Except he did the trip in some 2hrs and I would have taken 8 hrs. The total Fuel used was exactly the same. That was a surprise.
  17. I usually always find inexperienced sailors way over estimate wave height. Even with NZ waters/tides/wind, it is very rare to get 8m seas. It is truly sobering to be in 5 to 6m and I can say that from experience having been in wrong place wron tide time off Wellington. You wonder how water can defy such logic of standing that high and they make you feel very small, even in a 45ft boat.
  18. I will try again. https://www.trademe.co.nz/a/motors/boats-marine/yachts/keeler/listing/2990542948
  19. Oh I see, what the?? where did that come from. I posted a link from Trademe.
  20. Ummm.....OK......so where am I?? The heading of the thread on my page says "Suggestions for Budget keeler 25-32 ft". Am I still down that rabbit hole??
  21. A very close rule of thumb is that for every 25A of power generated requires 1Hp from the engine. The reason I say rule of thumb is becuase a certain amount of energy is lost due to friction of the pullies/belt/s. So based on that rule of thumb, a 100A ALT output is going to require 4Hp from the engine. In saying the above, ALT installations of 85-100A is about the max when driven with a single belt. Above that current rating, it should be a twin belt system. but twin V belts have a lot of friction. This is due to that the V belt is driven by contact with side of belt and side of pull
  22. How about this one https://www.nbcnews.com/politics/politics-news/aoc-raises-2m-texas-relief-heads-houston-after-blasting-cruz-n1258389
  23. It is not an easy question to accurately answer. It's like, how long is my piece of string and is it longer if I change the colour from blue to red, but what if the Blue has a green shade. The ruff rule of thumb is, that between no load and full load at the same RPM, there should be a difference of 20% in fuel used. This is because the Fuel is injected at a set dose per cylinder each time the Piston gets to the top of the bang stroke. As the load increases, the RPM will fall away and the governor opens to add a little extra fuel to give more bang and hopefully maintain the same RPM. The Fuel
  24. Hmmmm, I dunno, I have issue with several points. I don't think the story he tells has many "alternative facts", However, if we discuss this from a "Lessons to be learned point of view". First question, where was the guy coming from? The whether was such that no one should have been out there unless they were well equipped and some minor level of experience. It seems that from view of the story, this guy was not well equipped, nor had the level of experience. The story suggests he did not know much about VHF and especially CH16. That suggests to me he had little experience and should not
