  1. I have a 60C (bought in 2004 if memory serves) but can't help you as it still works and is used. /Martin
  2. I have done it yearly for about two decades with no ill effect. I use mesh 'bags' to avoid major tangles and I do not wash anything with metal hardware. Bare Dyneema is also kept out of this. 40 C program. Normal detergent. /Martin
  3. Temperatures look nice enough though. I think we peaked 14 C today. In the sun, that is. I did some adventurous boat painting with 2-part stuff after the last squall. /Martin
  4. I do remember attending the local boat show but not when it was. The most interesting part was the corner where they showed cartoons for kids. Antipodean boat shows seems to be marginally better at best. Some years earlier I did go to the London Boat Show. That was interesting because my friend who brought me there knows everyone in sailing through his work. His father filmed the first round the world race and was ships mate with Peter Blake. /Martin
  5. I have not heard about this dude before and I don't intend to watch his self chronicled antics. There is simply too much of that out there. Not a Kiwi view but something a Canadian who had lived for decades in the Caribbean once wrote in a forum when people complained about being 'ripped off' by locals when sailing there. From the top of my head so not verbatim: The mere fact that you have time off, time to go sailing for pleasure, makes you a walking wallet in their eyes. /Martin
  6. Inspired by ChatGPT's eloquent lack of information I just had to try out a much, much older chat bot called Racter. Here are a few lines of our conversation: Racter: "Hello, I'm Racter. Are you Martin?" Me: "What do you know about the silor that was rescued during cyclone Gabrielle in New Zealand?" Racter: "I may call you Silor, then?" Me: "Well, yes" Racter: "Hello Silor. I believe you're interviewing me. Are you continuing Martin's interview?" Me: "yes" Racter: "Well, Silor, Martin and I were talking about depression last time. Martin had just asked me whet
  7. Thanks even though our weather is quite benign. I took a quick peek. Very, very much 1960s Sandefjord, by the way, is a Norwegian city. /Martin
  8. That was what we used in our fresh water tank when I did my military service in the Swedish navy 40 years ago. I don't remember the dosage but we always added some when filling water tanks. Hydrogen peroxide was also part of the fuel for some torpedo models but that is another story. /Martin
  9. Not arguing against that. I just wanted to highlight that clutch performance depends on the line. More than I thought a few years ago. /Martin
  10. Clutch holding depends a lot on the line. /Martin
  11. Seems low to me. Anyway, halyards are about low stretch not breaking strength. /Martin
  12. Sorry for being so brief. I was about to leave for work. That climbing HW mostly made from high strength aluminum alloys. A friend of mine owns a Tornado. He is also a climber so knows about this type of gear. He noticed the excellent strength to weight ratio and thought "Why not use this on my boat?" He checked with his brother-in-law who is a pro climber and importer of climbing gear to Sweden. Brother-in-law said "Bad idea". Corrosion kills these alloys in no time and then they crumble under load. Swimming with that gear is probably OK if you rinse it afterwards but storing it in
  13. Keep in mind that those things are not corrosion resistant. /Martin
  14. I use a bowline knot for my jib halyard since 2+ decades. For spi I want something with a swivel so not knotted. If I ever convert my main halyard to 2:1 it will be knotted to the mast top. /Martin

    Garmin760s

    Reminds me of: My first GPS, a hand-held unit bought in 1997, eventually started to behave erratically some twenty years ago. At first the display was bad and then did not show anything. The device was way out of warranty and I am an electrical engineer working for a major telecom company. We have decent labs... But how do I get into the device? I was stumped. I contacted Garmin, told them who I was, where I worked and what I wanted to do. I was actually given the email of one of their technicians/engineers in the U.S. and he told me how to open the device and wished me good luck.
  16. This Sunday: I cleaned bottoms from some green algae on Saturday using my secondary method. The ease of cleaning has not changed over time. The bottoms are clean save for a two small patches I missed. The paint look 100% intact and the mildly hydrophobic behavior is restored after each cleaning. I would guess it would work for at least another season as is. I will, however apply a fresh layer of paint hoping I will achieve a smoother finish this time. /Martin
  17. Life is very opportunistic. /Martin
  18. I will know nothing about that until April or May. There will be an update if I observe anything interesting when the boat leaves the water for this season in a few weeks time. /Martin
  19. My plan was to wait till after the boat was out of the water. In short: Works as advertised by which I mean, yes things grow but they are really easily removed. This includes barnacles. I can't just brush them off but a mild nudge with a finger is all that is needed. I have had to clean the boat more but since the work has been easier the sum of work is roughly the same. The only disappointment is how rough the surface is. I have done some more research and now I know what to use for thinning this paint. I will try that for next season. I doubt you really have to repaint each se
  20. Finally hit water today. /Martin
  21. All about the boat here: https://www.reflectometrist.eu/ /Martin
  22. Yes, I intend to keep you posted. Yes, short mohair roller. I was coached on the procedure by a recently retired Hempel employee who my old boat building buddy knows through his job as a marine engineer. Disclaimer: my coach admitted that he had no first-hand experience of applying Hempaspeed TF, I will try to quantify and document the 'smoothness' before launching. /Martin
  23. So I ended up doing a complete antifouling 'facelift'. It cost me a month of our sailing season plus, of course, a bunch of money. I went for Hempaspeed TF which is not silicone based so this post is off topic. Hempaspeed TF is a bit odd to apply as it is rather viscous and I found it would not flow to a smooth surface which is a bit of a dissapointment after all the work. It is glossy which is also a little odd for an antifouling in my experience. It will be interesting to see if algae and barnacles like it. /Martin PS It is my understanding that Hempaspeed TF is currently
  24. Kim Klaka used to hang out on rec.boats on Usenet. He is (used to be?) a researcher at an institute or uni in western Australia. Lars Larsson used to be a hydrodynamics professor at the university I got my degrees at (*). My brother was one of his PhD students. My brother met Kim Klaka during a trip down under in 1995. Now this pops up here. Small planet /Martin *) My boat was built in the workshop of the marine engineering department of that university. Usenet: https://en.wikipedia.org/wiki/Usenet
