Lessons learned:

  • Should have bought 30m of 40x18 oregon pine in lengths of 5m instead of 6x2m. Need 40x18mm for seat supports, rudder (ruddercase and tiller), boom crutch and various small items.
  • Use elliptical moulds for hatches and openings. Rounded rectangles are less attractive because they seem to droop. They also have bigger cutouts for same width and height, so they weaken the bulkheads slightly more.
  • Draw all items like seats, daggerboard case, deck beams and seat supports 1:1 on the bulkhead before starting with hhatch openings. That way you know how much area is available.
  • Determine the size of hatch openings using real-life items like sleeping bags, cooking utensils etc. as models.
  • To determine the location of hatch openings, imagine there is 10cm water sloshing about in the bilge. Also imagine if hatches are under water if the hull is capsized.
  • Preparation is everything! Do not starting cutting until you have drawn every item on every bulkhead.
