      Ok, Ive read that MAIB article now and it hasn't changed my
      perspective on Cynthia J very much, if any. The boat would still be
      better, from a self rescuing and comfort point of view, for updates
      made along the lines of Otter ll and similar. Yep, there is little
      point in modifying Micro in the current Cynthia J direction, and
      losing the stability and offshore capability, but Cynthia J would
      benefit enormously from small attention to bouyancy and ballast.

      PCB suggests the increased bottom thickness, and some extra
      flotation in the quarters, also the 290lbs water ballast Rick
      included to stop her going over and flooding like Martha Jane un-
      revised, and Anhinga. I think a bow well would be better than a mast
      slot alone as he suggests. The forward frame, middle bulkheads,
      companion way, and storage mentioned in earlier posts would be
      worthwhile little modifications IMHO.

      In this article I think PCB looks at this hull as a big family's day
      sailing dinghy rather than the comfy camp cruiser she might be. He
      observes that more than one up, indeed with only two crew, it is
      hard to trim the boat as it should be. If the seating places two
      crew's weight too far aft of the C.O.B might not correct placement
      of stuff stored in the cuddy balance it?

      On the other hand, if the cabin is shortened to allow forward
      extension of the side seats a comfortable cabin is lost for little
      gain. This hull is not of his advanced sharpie type as PCB implies
      in the article. It is a flat iron, as I understand the term. It
      follows H I Chapelle's doctrine for sharpies of a long, dead-flat
      run to the turn of the bottom. As such, crew weight placed further
      than just a bit forward of where the seats are now will have the
      undesirable effect of burying the chine forward with all the bad
      follow-on effects that PCB has warned of so often. So, if crew sits
      forward extra weight will have to be placed in the stern, and the
      cabin is gone. With more crew this could be easily arranged, and
      would suit, but it then is a very high sided dinghy.

      As a cuddy camper this boat would be so good. Awaken, coffee, then
      so easily bulk sail is hoisted to ghost off on the day's adventure
      with the breeze hardly stirred in morning's first light.
