    About the jubilee clips. A stainless clip with a steel screw will have a W4 marking on it. A fully 316 stainless one has a W5 mark, that’s how you keep them apart.

    As a former Rigger I would always use anti seize (copper or nickel based) on important threads like turnbuckles. Once you have a galling event that requires a disc grinder cut off wheel and buying a new turnbuckle, you don’t take the risk with dry threads.
    If you have the tools, doing a light polish on the threads removes any tiny burrs.

    Excellent video. I wish a lot of well paid engineers and designers new this! This video should be part of the curriculum for materials guys. To be honest I’m sure they get this info. But the amount of improper design I come across is incredible and that’s before we start talking about dissimilar metals in contact. As for our boat I’ll have my wife out polishing again when the snow clears ;-).

    Enjoyed your video and would like to point out that 304 and 316 grades are now dual certified and will be marked 304/304L and 316/316L. The "L" for both simply means "low carbon". These dual certified grades were developed in the late 70s/early 80s and are particularly important if the stainless is to be welded. During the welding process, the heat affected zone will "draw" carbon molecules causing the weld area to rust if not annealed after welding. "L" grades were developed to limit carbon content to .04 maximum. Your advice to use a magnet to determine the quality is perfect, especially when searching for 316. Monel is an excellent upgrade for metal parts to be used in a seawater application, but its pricing will be substantially higher with limited availability. The boating consumer should also be careful when purchasing stainless steel shackles too as most are manufactured in China from cheap stainless steel. Another important metals topic for the boating community involves the multiple grades of aluminum. The best grade for seawater applications is 5086, a member of the 5000 series. Aluminum parts (masts & booms for example) are generally anodized for enhanced protection and are from the 6000 series of aluminum grades. You mentioned duplex stainless steels, which possess characteristics from both martensitic and austenitic. An example is 2205.

    Hi to you both , we love your videos and watched all through the last two years , it kept us going !! We are from uk and live in cyprus , we are going to sail from may this year.
    Do you think we would need AIS and Radar ?
    Keep up the videos and we hope to meet you one day, Phill

    • @SVImpavidus
      @SVImpavidus  Před 2 lety

      Hi. You do not need either however they are both very useful. Radar will show up small boats and markers that do not have AIS and those fishing boats that turn theirs off! Radar is expensive but shows everything. AIS is also expensive to set up and you may want to consider a receiver only that is compatible with your chartplotter. NASA marine of the UK make a cheap AIS receiver that uses NMEA 0183 to transmit to a plotter.

    After this, I will always carry a magnet when shopping for stainless. Please, look at some rust preventers that are used by bikers. Recently a lot of progress has been made that should be applicable for us cruisers. Search for XCP Rustblocker or ACF-50. Lots of bike tests on YT. Food for thought. Cheers.

      @@SVImpavidus To my deepest regret, I have nothing to do with Titan. At the moment, for a number of reasons, I am a sofa yachtsman. There was a period when he worked together with three-time Olympic champion Valentin Mankin, and he made his first navigator's pad with a parallel ruler of Admiral Makarov. Nevertheless, the love of the sail is forever. I'm sorry if I didn't live up to your expectations.

    • @SVImpavidus
      @SVImpavidus  Před 2 lety

      Mine does not stick anywhere I just checked it. It may be some induced magnetism from the forging or welding. This can happen but it is usually very lightly magnetized. Just be sure the ships compass is moving Steve and does not keep saying the bows are always north :-)

    • @SVImpavidus
      @SVImpavidus  Před 4 měsíci

      Stainless is fine. However, you have to know its limitations and how it performs. Even now there are big CZcams channels in the US suggesting that you re-torque your keel bolts if they are stainless. Bronze and even Titanium have been used on some boats and that's ok but again both have limitations. It is the old danger of people not knowing what they dont know that is dangerous. Sail Safe mate.
