      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.

    Amazing accomplishment. So glad to see that all the design and study and trial and error has paid off so fantastically!

    Ok - How about this.... As the bag collapses under vaccum pressure, it pinches in on the edges before it comes tight against the inside of the hull. It can slide around the edges to some extent, but as it is pulled into the center of the curve the pinching against the edges causes it to pull with a small force towards the center of the hull, thus increasing the round. So everyone is right that the net atmospheric force once the vaccum is established is zero, but there are forces at work as the air is being removed, creating uneven tension in the bag that remains as long as the vaccum remains.

    And that is why Steve is a hero. A great yachtsman who cares to get others involved. I'm helping my brother build a ply-moth right now and we've already stole the idea of the puzzle scarp joint and it worked awsome. Steve, is that fishing monofilament you're using to lace up the hull?
