    Chilean Anchorage Notes....

    Thanks. With the photos that's an interesting read even though I have no plans to go to Chile.

    The Rant

    Nothing wrong with being who you are and sharing your passion. One fact to consider is that there are a number of barriers to sailing that are invisible to most anarchists because they have become second nature to them. Mainly these are "building block" skills that were taught in summer camp, boy scouts, community ed, and similar programs in another generation: Basic comfort in and around the water Reasonable swimming ability e.g. 200 yards and 10 minutes treading water Some sort of basic map or chart reading skills. Rudimentary mechanical knowledge, like how to tighten something with a screwdriver or a wrench, and the names of fasteners and tools. Some sort of ability to work with fiber, e.g. sewing or knots or whatever I think it is important to meet people where they are.

    Dinghy build: Two-Paw 8 nesting

    It is my experience that there are few situations where cutting a straight line is important in boatbuilding. Being able to cut a curved line, however, is invaluable.

    Battery Date Codes

    Sometimes it matters but not always. Of Olden Time, the way it always was, batteries were shipped dry and stocked locally, and the distributor (usually) or dealer (less often) would add electrolyte and charge them just prior to sale. Lead-acid batteries don't start to deteriorate until the electrolyte is added, so a battery manufactured 10 years ago could, under that system, still offer a full life at the time of retail sale. The way the system was supposed to work, if a dealer had batteries sitting on the shelf for more than about six months, the distributor would take them back and usually sell them as seconds or derate them or something. With more batteries being sold by home centers etc this system has broken down somewhat and there is a greater chance of getting an older battery because margins are tight, everyone is making $12 an hour and no one cares, so there are old batteries on the shelf and you can get a bad one.

    Battery Date Codes

    They don't deliver as much current as starting batteries. That's it. You won't hurt the batteries. It's just that the engine might not start, especially in marginal conditions (cold). Sufficient large deep cycle batteries work fine for engine starting.
  6. The loss of s/v Rhapsody due to a fire originating in a lithium ion battery pack (in a cordless drill) is detailed in another thread. The loss of SCUBA diving livaboard vessel Conception earlier this year has also been blamed on a fire originating in lithium ion batteries. Small to midsize lithium-ion batteries are common aboard, especially on cruising boats where it is useful to bring cordless power tools. I would like to start a discussion of reasonable best practices for handling lithium-ion batteries aboard. Ideas for discussion: Purchase higher quality, trade-oriented rather than consumer-oriented tools, and use OEM packs, as these products have more attention given to cushioning and protecting the cells from impact. Don't use rebuilt packs (old pack with new cells) or "resurrected" packs (where the pack shut down internally but the safety mechanism was reset). Consider storing batteries in a fireproof container whenever feasible Avoid products that use loose li-ion cells, notably dive lights, as the cells are susceptible to impact damage when not inside a pack or device I offer this link to some videos on fireproof storage:

    Gulf of Mexico rescue 250 SE of Corpus

    The CF posts don't name the drill manufacturer or specify whether the battery pack is OEM or aftermarket. I am in the process of selling my air and corded electric power tools and replacing them with battery tools. It is troubling to think of the risks posed by the batteries. I'm getting Milwaukee tools, mainly because Milwaukee places greater emphasis on making both the tools and the packs resistant to impact and other abuse. There are photos and videos of disassembled packs that show the cushioning around the individual cells, and that show the fusible links that serve as last-resort short circuit protection. Youtube is full of videos of people "revitalizing" and "resurrecting" packs (from various vendors) that have shut down due to low voltage, shorts, or other reasons. Many times this is done to produce a functioning tool for resale. It's dangerous, because once a LiCOO2 cell has suffered those kinds of events, they're unstable. Or at least they might be. So it's just as important to know the provenance of the packs as it is to buy quality brand packs to begin with. It would be helpful to have best practices. I would imagine that keeping these batteries in a cheap discount-store fire safe would be enough to contain the fire. You know, the briefcase-sized ones designed to protect documents, that have roughly 1" of insulation saturated with water between their inner and outer walls. They aren't gas-tight and would vent, and there isn't enough energy in even the largest portable battery packs to exhaust the heat of vaporization of the water in the insulation.

    Most of the under 30', 50 year old production boats in my area either have outboards or an Atomic 4. The diesel sailboat auxiliary was unusual in 1970 at least in the LOTF/RBA. Atomic 4s tend to be a death sentence even if a repower isn't strictly necessary, because of the trouble and expense involved in making the (gasoline) fuel system reliable, free of leaks, and otherwise safe. I've never been on a boat that had one but by all reports they are, when properly maintained, excellent auxiliaries in all regards except fuel economy. They are quieter and smoother than diesels of the same size.

    Keep off the Rocks!

    There is Dioptra for Android and iPhone. On my phone everything is off by a degree or two; the app lets you enter a manual compensation for the compass but nothing else. With care and some manual averaging and compensating you can get within about half a degree vertically and two degrees horizontally (assuming a stationary platform). I think it's probably almost as useful for basic surveying as the old-school handheld tools -- the pocket transit and Abney level.

    The radar-equipped albatross

    https://arstechnica.com/science/2020/01/researchers-track-fishing-fleets-by-putting-radar-sensors-on-birds/ Interesting article about fitting albatrosses with radar receivers and satellite data transmitters, then comparing the results to satellite AIS receivers to see who is shutting off their AIS while behaving badly. I'll grab my tinfoil hat now
  11. The Icom M802, the only GMDSS compliant HF radio on the market that is feasible for use on cruising sailboats, is now discontinued and replaced by the M803. The M802 has been technically out of compliance with some of the FCC requirements for DSC implementation and was sold under a waiver that expired 12/31/2019. The M803 corrects the compliance problems. The M803 is in compliance with the FCC DSC rules, has a built-in GPS, and requires a different cable for connection to the antenna tuner. The display is color. Otherwise, the two radios are reportedly very similar. Still no 24v support. Price has gone from $2000 to $2500. http://www.icom.co.jp/world/products/marine/hf/ic-m803/ https://www.sea-tech.com/product/icom-m803-ssb-marine-radio/

    FWIW that was a propylene explosion, not acetylene. Propylene is thought to be safer, as mentioned upthread.

    Dinghy repair help - fatty knees 8

    Hello ajwilson Welcome to sailing anarchy These are really minor repairs and so people are going to tend to recommend whatever technique and materials are most familiar and comfortable to them. Hence the diverse replies. 8' dinghies have inherent limitations; see Stan Grayson's 1981 tome "The Dinghy Book" for a thorough treatment of the subject. There is a 2nd edition; I haven't read it and don't know if it's any good. The point being that you may want to limit your investment. I use and recommend West System epoxy for these sorts of minor repairs. It's easy to work with, they have good publications and product support, and as a practical matter you're not going to save much money using polyester on such a limited scale. There is nothing about the lapstrake-style shape that will make this hard on the sort of minor scale you're working on. If you are repainting the whole boat I would start by sanding the whole thing. Any really minor repairs where you mainly want to seal the glass can be made with clear epoxy. If there are areas that need filling or actual holes or breaks you can use fillers or cloth. Clear epoxy is hard to sand so you want thin coats that don't have to be sanded to shape. Practice helps but an 8' dinghy is as good a place to learn as anything else. Read and follow the instructions on the Gougeon Bros. web site Then paint to taste. You will need a quart. You can get away with plain hardware store oil-based enamel, or yacht paint, or two part paint, depending on your budget and your goals for the boat. If you are just painting the patch you might as well use a one-part paint that matches reasonably well and call it good. I would use hardware store paint because you'll be repainting the whole boat before the patch needs repainting anyway. Have fun and enjoy the result..

    Caliber 40 LRC with previous lightning strike

    I saw the ad for this boat on YW also and was intrigued. A fact to consider is that the boat had a good deal of updating as a result of the repairs. Other, comparable Caliber LRCs on the market are not only priced higher, they have (as a rule) 10-15 year old electronics.

    For me, the point at which Delos jumped the shark was the moment when they ran a "crew contest" and had people send video applications to become crew. They published excerpts of these on their channel. Then brought on someone they already knew as crew. Passing off things as true facts when they are not has a long and storied history of pissing off the audience https://en.wikipedia.org/wiki/1950s_quiz_show_scandals https://en.wikipedia.org/wiki/Milli_Vanilli#Lip-syncing_exposure_and_media_backlash,_1989–1991 The trend in boating videos and indeed youtube in general has been towards false drama and away from the uplifting videos that chronicle quiet competence and skill.
