  1. Nope, the eutectic system has stayed exactly as it was. There was a SS heat exchanger and thermostatically controlled fan that took air from fridge, blew it thru the wall to the freezer side heat exchanger, which is sealed from the freezer air, then returned the cold air to the fridge, lower down. It basically "borrows" some cold from the freezer to run the fridge. Means I can have one compressor system to do both jobs, the original Ozefridge AW480 twin eutectic tanks, with water cooling when needed. So all I changed was the freezer side heat exchanger - same footprint, just aluminum now... a
  2. This is a good read. https://contigoyachts.com/losing-everything-but-nothing-the-story-of-how-a-whale-sank-my-boat-in-the-middle-of-the-pacific-ocean/
  3. So I should add to this. The heat exchanger did not work great. Following some further testing and fabrication, I replaced the SS heat exchanger with one made of aluminum. Turns out aluminum is a MUCH better conductor of heat than SS. Like more than 10x better! The results so far are very encouraging, the fridge stays at 4-5 deg, with only a box for the alloy heat exchanger. I can add some fins to it easily if I need too in summer or the tropics, but right now it seems great. So, if your doing this, make your fridge heat transfer system from Aluminum!
  4. Use a scraper, as frank says. About 1/2 the width of the blade at a time, work along. Surprising how efficient it is. I scraped 100 KG of antifouling off IT! Must have been about 20 layers... I know because I vacuumed it up and the bags were about 100 KG....
  5. Same way some people think they can out-think an industrial chemist. Or an epidemiologist with vaccines for that matter! It's nonsense 🙄
  6. But also you might like to consider why the additives were banned. Take tributinal tin for example. It causes mutations in small sea life - that often ends up in our food chain. Every story has different points of view...
  7. It has recently become apparent that multiple people are adding Ivermectin to their antifouling here in Auckland. I'd just like to point out that this is illegal. "Ivermectin is not a legal antifouling option in New Zealand, as the Environmental Protection Authority has phased out several harmful antifouling paints, and using substances like Ivermectin in antifouling paints may not comply with regulations. Always check current regulations and consult with local authorities before making any changes." and; "Illegal addition or use of prohibited antifouling substances in New Zeala
  8. Its certainly a project Richard has for himself - almost a new build - raise the gunnels, new deck, cabin, add a pilothouse, new interior etc etc. The advantages of being a a pro boat builder I guess. She will be, like most of Richard's work, a work of art I'm sure!
  9. I thought it was pretty cool, went aboard Rainbow 11 and some others, and the dinghy hall sure bought back some memories!

    Yep, this bit looks a bit miserable! The Data hub on Vixen has peaked at 40 odd knots.... Not ideal for going to windward! Stay safe everyone!
  12. Or maybe with a major leak in an engine room, keeping going with sterns to weather may not have been the best possible plan. How about heave to, and try to contain it. The water level in that engine room was above sea level, it was being forced in by pressure of water flow under way??
  13. This is an interesting read https://svmagicbus.com/sv-magic-bus/ Thoughts about what they could have done differently??
  14. Already done that- responses that is. It is unworkable in it's current format. It may be like the 2018? Version - never passed and not cited.
  15. Not even 12m I reckon, >13 only...
  16. Someone must know an inspector at westhaven??
  17. As CD said. Like all of it, up to the inspector. I don't have a plate, but my keel is connected to the bonding system, and is used as both a SSB ground plane, and ships ground. Bigger by a fair bit than a plate...
  18. Not stock, about 5 days from order. Commonly installed on hanse boats and others. Not as reliable as the rams. Normally seized solenoids and internal water ingress issues. It's usually not a big issue to put in a removable end on a ram, held by an r clip...
  19. This, as it's an alado furler. Has a 50mm plastic clamp on the stay. But with the 2 toggles it "should" self align.... Had done about 30000 miles though.
  20. Dual toggle at base of forestay pin at base, T connector above it. No sign of bending, thread is dead straight. The break is spotlessly clean and shows no corrosion. Yes there is a small tear on one side, maybe 1-2mm of ripped thread. This fitting, for some stupid reason was 1/2 inch, but all the other stays are 5/8. New forestay on today, all 5/8, and 10mm wire (up from 8). Last time the rigging was replaced I just asked the rigger to duplicate it. I should have looked closer!
  21. Ok, we were sailing yesterday fully loaded. But it failed at anchor today with a decent bang as the preload released. Damn lucky not too lose the rig...
  22. Well, this year id planned to replace the standing rigging on IT. Have to be sooner now, broke the forestay today, inside the furler drum, the threaded part of the swage failed as per pics below. Not my specialty, but seems to be an embrittlement failure which is not common. 14 years old. No visible corrosion.
  23. The issue is that it could be cracked inside the deck. You can't tell without removing it. AT 40yrs it's due anyway!
  24. This is moving too, and hides corrosion
  25. This bolt is likely pulling thru or broken. Only solution is to remove the bracket, clean it up and inspect carefully for cracks, crevice corrosion etc. A "quick fix" could result in considerable damage and loss of the rig. I don't like the flowcoat and sealant covering - can't see what's under it, and more than that part of the fitting has moved....
