    Learn to splice recommendation ?

    I don't know if the videos are any good but I do know that it takes practice. My first splices were awful. I will probably never be as good as the people who do it for a living. It takes me half an hour to do a splice. Most of them are OK but not picture perfect.

    1GM10 burning oil. Problem? Not a problem?

    If the head has a history of being run without oil you may have some slop between the valves and the valve guides, even if oil leakage in the head is not ordinarily a problem on these engines. On a diesel oil leakage past the valves is unlikely to result in any follow-on problems unless you run out of oil (though this is a real risk). On a gasser it would foul the plugs. You could pull the head and overhaul it but I am unsure whether that would be a wise use of funds and labor on an older 1 banger. As for the magick potions, well, save your money

    Kenyon Kerosene Burners...

    Your fuel is no good. Probably has water in it Actual 95%+ ethanol will burn at room temperature without a preheat, a wick, or a vaporizer.
  4. The received wisdom on other forums is that: The BVI already had a problem with arbitrary and capricious customs enforcement, although this is more capricious than usual While most observers have concluded that this particular episode was an innocent mistake, the pool has been peed in by other boats trying to smuggle people and goods BVI are following a public health strategy of keeping Covid-19 off the island, which has for the most part been successful Having to stay on one side of an imaginary boundary is a new navigational problem for cruisers. If this sort of heavyhanded enforcement becomes commonplace there will have to be a change in mindset and a change in chartplotter software. Not a good thing for the future of cruising. This sort of thing came to aviation in the 1980s and 1990s with the creation and expansion of TCAs and contributed to the decline of general aviation.

    Electric windlass recommendations? 33’ boat

    3% of peak load is overkill. 4/0 is overkill. Picking a couple of smaller windlasses out of the air, the Lewmar V700 draws 40 amps. The Lewmar H3 draws 85 amps. For the H3, you could run #4. 25 feet from the battery you would lose a volt at peak load, about 9%. If you're running the engine you'll still get more than 12 volts to the motor terminals. For the V700 you could use #8. Inadequate power chiefly comes from loose, badly crimped, or failing terminals and failing relay contacts. Really large wire -- and 4/0 is really large -- poses its own set of problems because it is inflexible and heavy, and puts large mechanical loads on the terminals, posing its own set of problems unless the equipment at both ends is truly designed for cable this large.

    Stainless Steel Surrounding for Origo stove?

    I do take your point and we have a shared background in many ways. It's your project and that's part of the charm. I'm just saying I've been there and have an Origo on my trailer sailor now (and on my old boat that is for sale), and find that I don't use it to the extent I anticipated. Post up on this thread in a year and let us know how it works out.

    Stainless Steel Surrounding for Origo stove?

    The only way I've been able to do it is by preheating the pan before putting the bacon in. Sort of like backing off half a mile and accelerating for a pass on a two lane road if you're driving a car with the Origo equivalent for an engine.

    Stainless Steel Surrounding for Origo stove?

    It depends on your plans for the boat and what and how you will, realistically, cook while aboard. I gather that this is your first cruising boat, based on your other posts. Realize that it is the experience of others that people new to cruising who purchase a trailer sailor do not ordinarily have it become their "forever boat." The Centaur is a small boat. On most boats that size, the stove, to the extent that it is used at all, is used to boil water or perhaps heat up some soup or stew. Galley space, maximum crew size, and absence of refrigeration auger against a culinary tour de force, even among sailors who like to cook and who are comfortable cooking in camp settings. The Origo has an infinitely variable output that can be adjusted anywhere between "simmer" and "medium." Using one to produce grease spatters is an advanced technique. My advice would be to put it back together with inexpensive materials, go sailing, and revisit it after you see how the stove works out.

    Splicing rode to chain

    I'm not sure there are any that are practicable. Kevlar, for example, is tough but it floats and is not UV resistant.

    Ethanol and outboard carbs

    1) It is my recollection that carbs still had to be cleaned and fuel systems went to hell prior to the use of ethanol in gasoline 2) Avgas is expensive. Avgas has lead in it. Lead is toxic to you and the environment. 3) Ethanol is not the end of the world. Like other gasoline, keep it cool, minimize exposure to the atmosphere, and don't buy more than you can use 4) Most people who complain about ethanol do stupid things like let their motor sit all summer with the same gas in it, which is going to be a problem ethanol or no ethanol. Or they are blaming the fuel for a lack of basic maintenance e.g. periodic replacement of filters and hoses

    Splicing rode to chain

    No, the point of chain is that it won't get cut or abraded by sharp rocks, coral, debris, etc. The recent studies have shown that there is no useful snubbing effect from catenary except perhaps in uncommonly deep anchorages

  13. 120 watts? Horror of horrors. Now, let's see, how much does an M-802 draw? How long does it take to download email and weather? Which uses more amp-hours for daily comms as presently practiced? Iridium draws power too if you actually use it.
  14. In general, and not with satellite phones in particular.... The way that sort of thing usually goes is that the "authorized repair place" will have a handful of common, high-yield repairs that they can do that typically involve swapping parts between incoming units. So for example if they get a unit that comes in with a damaged housing, and another unit with a board that won't power up, they'll swap parts, end up with one good unit, a damaged housing in the garbage, and a circuit board in the scrap pile. For most products, they replace housings more often than circuit boards, and so they end up using some new housings. They will also get a few returns that are perfectly good and so they'll just test them and repackage them. Eventually they'll go through the pile of scrap circuit boards, sort them based on type of failure, and fix problems that are common and easy to fix. Most often that means installing new connectors, since power, USB, and ethernet connectors (etc) are common failure points. Some electronics have known weaknesses, these vary widely, one that I worked on long enough ago that I can talk about it was prone to bad flash and so they had a process for replacing flash chips. It's all driven by cost and yield and scale. On a typical consumer electronics product they might get a 60% overall yield on repairs, at a cost (per successful repair) that is maybe 50% of the production cost of a new device, if your repair techs get a semi-trailer load a month. They track serial numbers and if they get a circuit board back more than once or twice after being unable to find anything wrong they'll just throw it in the trash. But, and this is the main point, failures of large ICs -- CPUs and the like with hundreds of pins -- are simply not repairable with reasonable cost and yield. They might try to salvage a chip or resolder a bad connection on a prototype if the chips are very expensive or simply not available, but with modern chips even with the best equipment and technicians it is expensive, time consuming, and succeeds half the time or less (depending on size and density of connections). So, no, the authorized repair place doesn't "repair" those as such. And they don't just sell you a "new" one. You end up getting someone else's widget that was easier to repair, in most cases.

    Splicing rode to chain

    Lots of reasons. On a smaller, dinghy-sized boat you might want to remove the rope so that you can rig a "clothesline anchor" where you drop the anchor off the shore a ways having tied off the end of the rode to the bow and passed the working end through the chain cleat then taken it onto the (rocky) shore, so you can pull the boat back to the anchor while you have lunch. You might need the rode for something else, maybe another anchor, or to extend another shorter rode. You might have something hopelessly fouled and want to save whatever pieces you can, or to deal with each part of the problem by itself, particularly if diving to solve the problem. In this particular case I did the splice because I want the whole thing to be light and easy to stow.
