  1. Russell, I have one of these: https://www.amazon.com/gp/product/B083ZMKZSX They are better in every way than the propane camp stoves except that they won't work as well in freezing temperatures. (Lighter, uses less space when in use since the gas bottle sits inside the stove enclosure, sits lower and therefore less tippy than many propane stoves, piezo igniter that works reliably, not prone to regulator freezeup, no need to unscrew bottle and store separately) The butane canisters have thinner walls like an aerosol can and can be recycled when empty with no special precautions
  2. I have an Origo in my boat and had an Origo in my previous boat. For clarity, these are unrelated to the Kenyon pressurized alcohol stoves of the 50s and 60s which contributed to many fires, which are fully deserving of the bad things people say about them. The great things about Origos are that they are self-contained and widely considered safe for use aboard. So, no propane system to purchase, install, or maintain, and nobody on the phorumz telling you that you're going to blow yourself up from a leak. That's where it ends. Fuel is bulky, expensive, and increasingly hard to find
  3. This is what happens if you don't finish your project before you die. Free for the hauling https://minneapolis.craigslist.org/csw/boa/d/rice-36-foot-sailboat/7315724867.html
  4. Reposting photos that were eaten by the server outage.
  5. 2010 30' Airstream, now sold. I spent 194 nights in it (kept a log). 1971 Cayo C-11, also sold. Probably about 30 nights in it. I had it about five years after purchasing it as a project, and sold it for more than I had spent. There are some great things about RVs as a form of travel or as a vacation lifestyle. As with a yacht, you get the juxtaposition of a new scene outside your door whenever you move vs. familiar accommodations. If you do it right, you keep the RV stocked and you don't have to pack before departing -- just stop at the grocery store on the road so
  6. Do you know much about them? The Klepper kayaks were quite popular here back in the day, that is, before the dawn and ascendancy of the rotomolding era. The kayaks, at least, are still made. They were, as a recall, not visually beautiful boats.

  8. I don't race but I do use that type of connector between batteries and boat. Great for maintenance and winter storage.

    CNG

    Take them to a hydro shop and either pay $20 each to have them hydro tested or give them away to the shop. The hydro guys are thorough. If they pass the cylinders, they're safe. Get an expired one and have it hydro tested and (optionally) revalved. CNG tanks are the same as other high-pressure compressed gas tanks except for the valve. A welding gas place should be able to fix you up with one. No, they're not free.
  10. Some photos. I tried epoxying the clamps and the epoxy would not stick to the aluminum clamps even with thorough surface prep, so I'm trying rivnuts. The antenna brackets are fastened using U bolts with a 1" diameter aluminum backing tube inside the mast to distribute the force.
  11. I think in most cases they're for separate bands. Historically it was either HF, CB, Loran, or AM broadcast. I don't know what they use them for now.
  12. dB, as a measurement of antenna gain, is only meaningful for comparing two antennas. Confusingly, the antenna industry uses two separate references: dBi -- which is dB over a theoretical isotropic radiator that sends equal power in all directions, and dBd -- which is dB over a dipole in free space. Since a dipole in free space has 2.15 dB gain over an isotropic radiator, it is possible to convert from dBd to dBi by adding 2.15 and convert the other way by subtracting The electrical configuration of this antenna is that of a stacked dipole, which has a theoretical gain of 3 dBd -- stacki
  13. It is a 3 dBd antenna, which is electrically similar to the marine antennas sold as "6 dB". Patterns vary by specific product. Here's the one from Laird for this antenna in particular: Let's look at heel. According to the pattern, performance starts to drop off at about 25 degrees of heel. The dashed line in the chart at 3 dB is unity gain over a theoretical dipole, and that point isn't reached until we're at 37 degrees of heel. The boat doesn't heel that much, it will round up first. And that 37 degree point is roughly the point at which performance is the same for a "
  14. Digikey search here. They will sell you one or a million and ship same day. Looks like you get your choice of color and manufacturer: https://www.digikey.com/en/products/filter/terminal-blocks-headers-plugs-and-sockets/370?s=N4IgjCBcoBw1oDGUBmBDANgZwKYBoQB7KAbRACYAGAZjADYB2EAXQIAcAXKEAZQ4CcAlgDsA5iAC%2BBMDGoIQySOmz4ipENRgMAnOQAsLdl0i8BI8VJC6m0Baky4CxSGWra6dAKyGQnbnyExSWlyGEp5RWVHNRdwMD19bR8-EwDzSUtydU8AWxyAAg4cfgKAIwxCRABrfLYMAFdxZgkgA You will have to measure the pitch of the pins to get the right one. Five pins per inch is most common (5mm or 5.08mm) but by no mean
  15. Metal stanchion? Easy, use heat. Heat gun works well and is less likely to damage surrounding areas than a torch. Nonetheless, use wet rags to protect the gelcoat and have extra ones handy in the event of fire. Tends to scorch the gelcoat and upset the neighbors. I looked at my slip rental agreement and there's nothing in there that disallows it, though.
