      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

  1. Kite boats

    Why haven't sailboats without a mast but only a kite caught on? Seems like there are many advantages including lack of heeling. Couple a kite with foils and you could have a really fast boat - sort of a big, foiling, kiteboard. For carrying loads in displacement mode, it would seem safer to add sail area without a mast. For sailboats with masts, kites could provide an easy jury rig.
  2. An even more modern way of doing this is to learn the control with a machine learning system such as a deep neural net. You may also not be able to figure out what it's doing but this approach has been much better for game playing, machine vision, language translation, and speech recognition. It should work well as a control system for the AC, assuming it's allowed. You could start in simulation if it's not allowed and refine it on the water in real time if it is.
  3. Deep vs. shallow keel

    Truth is the era of fighter pilots is almost over. Humans don't have the capabilities that autopilots and sensors will soon have. See https://www.wired.com/2016/06/ai-fighter-pilot-beats-human-no-need-panic-really/ for a primitive example.
  4. Deep vs. shallow keel

    One size fits none.
  5. Navy Luders 44 - Alert

    That Luders yawl is a beauty. Here's the current Navy 44. Collegiate regatta heading out on 420s in the background.
  6. Deep vs. shallow keel

    The fighter Luke Skywalker would choose. Careful with the landing.
  7. Deep vs. shallow keel

    Maybe?

  9. Coolboats to admire

    Not sure how cool it is but there's an active one-design fleet here. They sail well but I don't like the way the bridgedeck crowds the cockpit. That might be OK for a couple cruising. Also the bowed house top makes maneuvers like tacking a chore for crew. I like the transom hung rudder. They are super cheap these days and a lot of boat for the money so definitely a good old boat.
  10. Why isn`t it a code a negative 1

    It's the closest they could get to -1 without going negative?
  11. Since the concept in the simulation is a MonINO (Monohull in Name Only (TM)), I think, in the end, they will decide to add amas for RM and eliminate ballast and complication. This will be a safer design, will provide a definite change from AC35, and will be a face-saving device since, by squinting, LR will see a monohull. Win-win-win.
  12. Friends also gave him a much more substantial boat for his 50th birthday in 1929. Unfortunately, it was seized by the Nazis after he left for America and he couldn't get it back. Lines and other information are here: http://www.einstein-website.de/z_biography/tuemmler-e.html

    Gorgeous boat! Nice video.
  14. Is this Nantucket harbor?

    Could it be Hyannis? It sort of looks like that from the route of the Ferry to Nantucket.

  17. The old man and the sea

    Some people drift across oceans. Others take matters into their own hands - literally. See https://www.outsideonline.com/2252016/old-man-and-sea-and-sea-and-sea Adventure paddler Aleksander Doba willed his 71-year-old body and 1,600-pound kayak through a 4,000-mile trans-Atlantic journey Doba, a retired chemical engineer who skydived, flew gliders, and sailed before he started kayaking, never lost enthusiasm for crossing the Atlantic. “On the water, I never think about dying or that I could die,” Doba later told me through an interpreter. “The kayak is very safe.”

  19. Pulling your sail boat out for the winter

    Very few boats are left on moorings over the winter here but many are in slips.
  20. Wht havent' multihulls taken the world by storm

    I am not on the fence about multihull or mono but enjoy both. Each have their charms. It's hard to beat the thrill of beach cats or the comfort of a multihull charter in the Caribbean. Likewise it's nice to cruise a mono in the Chesapeake so you can fit in slips or race a mono in OD classes.
  21. Pulling your sail boat out for the winter

    I'd say you're in good company. Most boats in Annapolis stay in the water in the winter. Not sure why Baltimore would be different.

    Tubercules!
  24. Coolboats to admire

    Right. If the mizzen provides power it's a ketch. If it's only for balance, it's a yawl.

    The inhaulers seem to have the effect of many parallel jib tracks. It does get busy near the mast.
