  1. Good move. Better than ANY of the current new models IMO....
  2. LAT is lowest astronomical tide.. https://www.google.com/search?ie=UTF-8&client=ms-android-samsung-rev2&source=android-browser&q=lowest+astronomical+tide
  3. Any of the late model Simrad or B&G, plus most of the Lowrance MFD's will use public sourced - and/or make your own charts at 300mm (1ft) contours, with either Cmap or Navionics charts allowing overlays.
  4. Folded in 1/4 in chart table storage in a plastic bag, or rolled in screw together plastic tube for one's I won't need for some time.
  5. Lost gps position. Check cables, location of antenna - away from radar and other antennas
  6. Probably too many versions in between. Call navico on 08004628426 and they should be able to help. I'm away, and in poor reception area, back 21 Jan...
  7. Min 45psi, this is ok, https://www.burnsco.co.nz/pr-pump-wd-12v-60psi-15lpm-jabsco-kit
  8. I don’t think so. A well designed eutectic system can use no battery at all - hold overnight, run when solar or engine going and voltage is high. Thin plate systems can run pretty much all the time, battery full or low. the advantage lifepo4 gives, is that if you do need to run the system on battery, it won’t take long to put the charge back into the batts.
  9. I understand that they were also warned, by the designer IIRC, NOT to sail to Auckland for the repair, as the keel might come off.
  10. I have the standard 115a Mitsubishi Alt on my D2-40F, other variants have other alts. Eric (VRC-200 designer) says this is an excellent alt, and so far I have no reason to disagree. It has built in temp compensation, and seems to stabilize output at around 90-100 amps continuous (60 mins at that so far longest charge I've needed), which is surprisingly good. The batteries I have are indeed in parallels, but they are rated for 120amps EACH max charge and max discharge. No restriction in current programmed into the VRC-200, just letting the alt temp compensation take care of that, so the alt c
  11. OK, here is my current level of knowledge. I'm not a LifePo4 specialist, and currently experimenting! Why would you want LiFePo4 batteries. Light weight - for my tests, I've put in 2 120 a/h batteries giving 192a/h useable at 80% depth of discharge. They can each be carried easily in one hand. They replaced 2 200 a/h VRSLA batteries weighing 62KG each, and gave 200 A/h useable capacity at 50% dod. Life span - the VRSLA's give 400-1000 cycles - the LiFePo4 about 3000 cycles, both at the manufacturers recommended dod. Charging abilities. A good LiFePo4 battery can acce
  12. There have been some improvements in Drop in lithium over the last year or two. As BP says above, I've got a couple in Island Time right now, as an experiment. I will post on here next week sometime what I've learnt/found so far, but it's too Ling and complex to write on my ph, while I'm out in the boat. The basics are that they may be a low(er) cost lithium upgrade for some vessels. They are totally unsuited to others.
  13. Its Google Analytics. Its USERS - does not mean they post, but people who actively browse the site. Individual page views is much higher than these numbers. I agree that a very low percentage post, it's always been that way. What I wanted to illustrate, is that the site is now slowly growing again in users.
  14. Agree with MCP - but for clarification the supply lead to the switchboard should be a decent battery cable size - and be fused at the battery. If it is, no issue, and not really related to the AP switch, provided that cable has the capacity to carry the extra load. The load of a TP32 is not huge, average about 0.5a, max about 7a...no issues for the 15a switch/breaker.
  15. Nope. Here are the numbers last 90 days; Top line is monthly, middle is weekly, bottom is daily...
  16. Use fresh water. Some of the plastics that are used for bearings will absorb petroleum based lubricants and swell. They are supposed to be self, or water lubricated. Fresh water disolves salt pretty well. If someone has tried to lubricate it before, and it has plastic bushes/bearings, that could well be the issue
  17. Depends which ones - inside, outside etc. I get my outdoor foam from Topfab... Closed cell, free draining. https://www.topfab.co.nz/
  18. The rudder should be reasonably neutral buoyancy. Probably sink, but not by much. You must make a method of retention if you undo the nut. Also, it will capsize, and either sink or float stock down... My rudder probably weighs about 60KG, and is pretty neutral buoyancy. Don't loose the rudder!
  19. Ok, now a pic from under the cockpit floor, so we can see the rudder tube. This looks like it might be a tube from the hull thru the boat and cockpit floor. But there is little room under the tiller for a horizontal bearing surface. Could be rollers as well. Rollers likely gummed up/rusted or failed. Have to drop the rudder to be sure...
  20. There was, for a while, in June 2020. Been gone for ages. Read the dates people!
  21. Hmm, not exactly accurate. “12” volt panels often run at 20 odd volts with MPPT, and the voltage has nothing to do with low light ability. A decent controller will adjust the panel voltage to get the max power point -hence mppt.
  22. The Vulcan can only do basic polars, and what you are entering is a table. For proper polars, you need an h5000 processor.
  23. not much wrong with that motor, almost certainly insufficient fuel.... Filters first, then lift pump system pressure test....
