    That was a great video. I wish I'd seen this before I started sailing. It would have saved me from some scary healing over moments. Very informative. Thanks.

      awesome. glad to have you aboard. One of my favorite things about sailing is that no matter how long you've been sailing or how good you get, you almost always learn something new

    good explination, but I really clicked on it because I had the exact same Sunflower awhen I was 12 about 77. I sailed that thing all over, well beyond what I think anyone intended it to do.

      Yeah, I just refurbished this one! Thanks for watching

    I am converting a daggerboard to a swing keel on my snark, and adding a bowsprit and jib, from your explanation of center of effort and center of lateral resistance it sounds reasonable for me to move the keel position snug up close to the mast step. Any thoughts on if this is a horrible idea?

    • @JenkinsBoatWorks

      interesting! some of this clearly is a function of how long the bowsprit is and how big of a jib you might add. I also have question about the swing keel. Are you completely rebuilding a centerboard trunk? a picture or diagram of your ideas and final expectation would be great. email me something like that and I would be happy to give my thoughts. cejenkinsjr@yahoo.com

      second response - I just had one more thought. Are you going to have a more traditional mainsail rather than the lateen rig because that would be an odd combination with a jib, at least on such a small boat. I mean the way the yard and the boom come together forward of the mast, you have some sail area forward already. remember the old rule, if it can get fouled, it will. tacking with the original sail rig and a jib could be tricky. if you change the main to a luff strictly attached to the mast, you will reduce the aft sail area and then adding a jib. oh my.. the more I think about it the more I want to see a picture of your ideas and intention.

      They are quite the characters. my old dog with the white markings is Bandit. He will be 16 in September. He is old and cranky and slow and doesn't much like to put up with Golden Retriever puppy Toby's antics. Toby is a nutball. You can see him helping me with a paddle board build here: ruclips.net/video/4vsZaYD0cXM/видео.html

    what does the Jib sail do?

    • @JenkinsBoatWorks
      @JenkinsBoatWorks  2 года назад +1

      a great question. It works in tandem with the main sail. As discussed, especially toward the wind or on a beat to windward, the jib will force more air around the front side of the mainsail creating more lift. If you get both sails set just right, it is a very noticeable advantage. On a Run, downwind, you can set sail opposite sides or "wing and wing" creating more area for the wind to push on
