Updates to Plans

Sango

Use the hull spacing dimension from the drawing, not the photosheet. It should be 3700mm

Round Bilge offset table

Although the full size patterns are correct I still include an offset table for use as a check. I recently discovered a couple of errors in the table:

Frame 3 WL2 should be 215
Frame 4 WL3 should be 188
Frame 5 WL3 should be 202
Frame 8 WL2 should be 217

Daggerboard Position

The drawings show the daggerboard cases fitted on the outside of the hull. That is so that they do not interfere with the wing lockers. However the photo sheets show the daggerboard case on the inside of the hull. The builder whose boat I photographed chose this position to make it easier to reach and adjust the boards.

If building hard chine Wizard hulls then the daggerboard case can be fitted on the aft side Bhd4

There is no real difference in performance between the two positions so the choice is yours.
