  1. Disturbingly cheap. I haven't worked out where the exhaust comes out though. You do not want that in the Cabin. https://www.trademe.co.nz/motors/caravans-motorhomes/parts-accessories/other/listing-2640299135.htm?rsqid=b476dd40b01e49fda38854bd3344a218-010 Another "I have no idea how they do it" kind of cheap unit to consider is this https://www.trademe.co.nz/motors/caravans-motorhomes/parts-accessories/other/listing-2642039675.htm?rsqid=8846ccfcccc2494a89a965b672475b84-008
  2. I don't have an issue with what he did. However, I would have an issue if he did this without telling anyone where he was going. I also imagine he might have underestimated the distance and thus amount of fuel he needed. I suspect he broke down due to being out of Fuel. The distance he traveled is a heck of a long way and he would have needed a lot of fuel on board. The weather can turn nasty out there quickly and the tidal current is fast in places. Underestimating the trip time by not accounting for those two things is easy to do. A mate of mine and I have crossed the strait in a Jet Ski. He was on the Jet Ski and I was driving a 16ft support Boat. But we only went from Picton to the closest point of the North Island and back.
  3. The box must not get too hot. Heat is bad for everything, The ALT will risk being cooked and most especially, it robs Hp if your engine has to breath it. Make sure you have good air flow through the Engine box.
  4. They work well. Very expensive though

    Not having a sounder is like not wearing your seatbelt. It can also be a navigation aid when coastal cruising. Use can use it to follow depth contours and that helps plot your position on the chart. I hate entering an unknown bay without one.

    I cant say never when it comes to lectronics and that fellow Murphy. But it is not a common way for them to go. Normally it is go or no go. However, if you had no AF coating on it, then growth could once again be an issue. It only takes a week or so for any clear realestate to be snapped up by those marine invaders. You do need to put some kind of coating on the transducer. Just ensure old is removed before new applied so it does not get too thick.

    The reason it starts back up again when the power is re supplied is due to a yellow wire (I think it was yellow) being connected to the Red power wire. This bypasses the panel switch so as the unit powers up as soon as an eternal switch/breaker is turned on. That does not solve the problem of it turning off on it's own though. I imagine there is a cold solder joint internally. To be honest, I doubt it is worth repairing. Fish, your unit has possibly got fouling on it's surface. The weaker signal bounces off the Keel and it gets a false shallow reading. Too much AF paint can also do it.
  8. Jon, it's not a capacitor on the end. It is a temp sensor. The sensor is normally glued to the case of a battery, or samwedged in between the cases of two batteries. It is quiet possible it is faulty. They only way to really know is to replace it. You can do without it. It is not a circuit that has a lot of current draw, so no huge temperature variances during charging. If you ever needed to replace the Charge Unit, then go for the same thing again. They have a good reputation. DutyFree, you may need to explain a little more. It is just a 24V Charger that uses the 12V Bank as the supply voltage instead of 230V mains.
  9. The cheap Coolants need replacing yearly and there are a lot of cheapies out there. If you want a quality coolant without paying through the nose, the Penrite range is extremely good, with their top end coolants having a 5, 7 and 8yr cycle life. However, when using coolants that can span that far, I suggest you get a test done every couple when getting toward the far end of it's life. Coolants are the wrong word to call these additives. They do cool to an extent and they also safe guard against freezing, but the most important role is anti corrosion. They are Corrosion Inhibitors. I have seen engines that have had holes through cast iron blocks due to running with no inhibitor. The Nissan TD42 engine and Cummins engines are common for holes through blocks. Any engine that has a Cast block and Ally Head MUST have an inhibitor added. That's simply a case of dissimilar metals in close contact causing corrosion.
  10. The story as told from the Cpt of Monawai is a spectacular read as well. http://www.bluesuit.co.nz/1994.htm Yes we have better weather prediction these days, but i think more importantly, we have a lot more heavy weather gear available as well. Especially the drogue department. The account from the owners of one particular Boat we looked at was the reason why we went FC. They sailed right through this along with a group of other FC boats and arrived in Fiji with no knowledge of what was going on out there behind them.
  11. As alternative fuel/electric vehicles increase on our roads, this is likely to become the best way of charging road tax. Although it is also a way to rip of small vehicle drivers unless the system becomes more complex. For instance, we used to have a 2 tonne and 3 tonne rate. Now we have one rate of 0 upto 3.5 tonne. So vehicles within that 3.5 tonne are all charged at the same rate of 0.072 cents per Km. Where as with the RUC held within the fuel tax, smaller Vehicles paid less because they tend to use less in the way of Fuel. It was a little more fair.
  12. I was watching an interview on TV and they had a question answer kind of thing with the Person being interviewed. I cannot remember who it was they were interviewing. It was either JA herself or perhaps it was the head of Police. I have been watching far to much and it is all blurring together now. All the things i listed were a No and the reason given where as I said. They even stated that this is why Hunters can go onto Private land (if they can find a Farmer that will let them) but not Doc land. Because if something went wrong, S&R would be involved, and they do not want that. That does not mean S&R are not ready and willing to go if needed. It shows that there is a severe lack, plus confusion in communication between Gvt and authorities.
  13. All these can I, Why can't I questions are very easy to clearly answer. Under level 3, you can pop down to the boat to check it over, but there are stricked rules in relation to keeping distance from other people. However, you cannot row out to the Boat. Reason is, rowing out puts you at risk of something going wrong and if something goes wrong and you need rescuing, then you put the rescuers at risk. So you cannot row out to a Boat on a Mooring. I know it's silly and there is greater risk crossing the road than falling out of the Tender, but them''s the rules and that's the reason why. This is an Email from our Marina today in regards to the rules in the Marina
  14. Yes absolutely. Is it worth you listing some Chargers that have all those kind of bells a Whistles IT?? Especially if you sell any of them
  15. It's all a bit more complex.....as usual when it comes to batteries. Firstly, keeping a trickle charge on a battery is good. Can't go wrong with that part. But that is not the end of the story. Basically, it doesn't matter what you do, a Lead acid battery deteriorates in same way, even left fully charged. From the day the battery was born and accepted it's very first charge, the Chemical reaction that creates the Electrical energy, slowly eats away at the life of the plate. Also, once the plate voltage drops below 12.6V, the plates start to Sulphate. Trickle charging will stop sulphation from happening. Trickle charging is at a very low current and lower voltage than a normal charge voltage, so you do not have issues with a battery getting hot or boiling. BUT!!!!! Trickle charging does not mean the battery will remain in tip top health forever, being an eager slave just waiting to please the day the master switches on a load. FLA is the one battery type that needs the most maintenance. FLA's need to have the Electrolyte levels monitored and topped up when needed. Having special caps fitted to Deep cycles will aid in keeping the levels maintained for longer. But! in float charge, FLA's suffer from Stratification. This is where the denser Acid in the Electrolyte drops to the bottom leaving only water at the top of the plates. It is good practice once a month (ruffly, it's not critical to skip a month or two for some reason ) to apply an equalization charge which stirs the electrolyte up and also helps to balance charge across the cells. This is why Gel cell batteries tend to be used in remote backup power sites. They don't experience stratification of the electrolyte and thus a cheaper charger can be used. You may have noticed comments in the past about "surface charge". Trickle charging is when this issue tends to take place. A plate does not charge evenly when a current is applied. The charge starts from the surface and works its way into the depth of the plate. This is why a Battery takes time to charge. The Chemistry change has to work it's way into the depth of the plate. Sitting on a trickle charge for extended times does not mean the entire depth of the plate remains fully charged. Within the plate, the charge will start to decline and eventually the surface only holds a charge. Testing may show a fully charged battery. But if you place a load on the battery, it's charge will drop away quickly and the battery will be flat. So once a month, the battery really needs to be placed under a load for awhile to ensure the surface charge has been used up. Then the battery is placed under a full charge and once fully charged, placed under an equalisation charge. There are a few top end Chargers that do this automatically and this is where you discover why some chargers are damn expensive. They are also very clever. However, even on a tickle charge, eventually the battery will still die. The plate material slowly breaks down and the chemistry can no longer be maintained.
  16. The PM made it very clear in her speech yesterday that any on water activity is still banned, anything done on/from the shore is ok.

    Anchor winch leak

    Hmmmm, I think you would be better going to a Rope/Chain rode if weight is an issue and reinstating the locker as it used to be. The only other thing is to build a bulkhead that will enclose the anchor area and channel the water etc along with the chain into the forward locker. Have you noticed any great improvement having the weight of the chain lower and aft of the original chain locker?
  18. Surface charge is not a thing in this instance. As a Plate charges, it starts from the surface and the charge works it's way in toward the center of the plate material. Surface charge is when the internals of the plate have no charge (a couple of reasons can cause this) and only the surface has a charge. The Battery can be voltage tested with a good reading of a charged battery. But the Battery actually has no Current available. So with a load placed on it, the Voltage will simply drop away. The Efficiency part I was referring to is the Efficiency of the ALT itself in relation to the temperature of the ALT. If it is really hot, the resistance of the copper windings change and the magnetic field becomes weaker, thus the ALT will never deliver the Current that it would normally be capable of. Those time intervals where the ALT is not producing a current would be a cooling period on for those Windings. If you also note the graph, the initial leading current peak is higher than the end of the charge period and that could well be the heat rising causing that ALT charge efficiency dropping slightly. As the cycles continue, the peaks are ever so slightly higher ( I think, without going back to check) There are other mechanical causes that can do this as well, so my comment is not something to take as fact without knowing a lot more about the installation.
  19. No disagreement IT. I thought I had made the same point about the 14.1 should be 14.4. I went back and re read my post and see I did not make that very clear at all and in fact messed up the comment completely. And I can't even use the excuse of posting in the early hrs of the morning either. I see it was 5.30PM. So I stuffed up there. I don't know enough about what the Batteries are and the finer details of the Reg to personally say go to 14.7, but most certainly 14.4. is the essential Voltage point for the reg to be set to. If you go above 14.4, monitor the bank for a few charge cycles to ensure they are not over cooking. Or as IT said, if you can possibly get that information from the Battery manufacturer. Question, does the Reg have Temperature monitoring of the Batteries ?? Temperature is very important. The ambient temperature between Summer and Winter can make an enormous difference with the current output that the Reg will make the ALT produce. I used to use the Ambient Temp setting when I wanted to push a higher charge current into the Bank and the Charge Voltage rose, so as the charge time was reduced. But that also means you have to monitor the Bank to ensure they are not getting hot and to watch the ALT that it is not being pushed too hard. Ambient Temp will also make a huge difference in what the batteries will accept. So having an actual sensor can be a big advantage so as the Reg follows the Banks temp/ charge curve

    Inverter help

    I was about to say the same thing. You beat me too it IT

    Inverter help

    It is best to ensure that what you are wanting to power, does not have a higher starting current than the Inverter can handle. Just as an example, for older Microwaves, they need an inverter that can supply 3x the run current to start them. The new inverter powered Microwaves have soft start, so not so much of a problem. Make sure you go for an Inverter that has a Pure Sine wave output. This will run anything electronic. Many electronic devices, like say a TV, can be noisy on a sh cheaper Modified Sine Wave output. Some digital devices like say the display on a Microwave, may not work at all with a noisy supply. I would also go slightly larger in output, providing physical size is OK. So for instance, if you need1700W, go for 2Kw. Apart from that, IT has given you some real good names if you want quality.
  22. Are we talking an Elliot 1050 ? If yes, Greg Elliot would be the best person to talk to. He designed and fitted a T Keel to "Cutting Edge". He is going to be the best person to tell you what needs to be done to the structure of the Boat if any. Cost is also going to be different depending on how much you do yourself or if it is done by a professional yard. I am out of my depth on this part, but I would expect that to be able to maintain a Cat number for racing (depending on what racing you want to do) you may need a properly engineered design, hence Elliots involvement. You may also get around having to do stability tests because Elliott will likely be able to proved all the figures and the fact that he has done it before. New one off's can be fraught with all sorts of expensive issues otherwise.
  23. Looking at the smoke from the Exhaust, the wind was not that bad. But the exhaust sure was telling a different story. One of Engines being rung on hard. I would say they had a control issue.
  24. I set ours up pretty much the same as the Pic above. We had two levels of spreaders however, so the set up was slightly more complex. The only issue I had, was that the Main was a high ratio cut sail. So the top narrowed down very quickly. This resulted in the very top batten often getting caught in the jack line as I raised the main and if we were off the wind too much. Like for instance, we may have been under Headsail only and decided to raise the Main, but didn't want to round up into the wind and have the Headsail flap about against the Inner Forestay. I could never quite get the mounting positions just right. So in the end, I tied bungy to the Jack line and the opposite end on the lower spreader out wideWhen the jack line was pulled taught, the Bungy would allow the jack line to pull aft and in toward the Sail. When slackened off, bungy pulled the jack line out and forward toward the mast. So I only pulled the jack line tight when about to lower the Main. The rest of the time, the bungy kept the Jack line clear. I also had a stack pack. Like BP, I cannot oversell this idea. It is simply life changing to be able to just drop the Halyard and let it all fall into the bag, most especially if the wind is up.
