This is at table of the hull half-widths in inches, stations are 12 inches apart. The bow is Station 0. Above the datum line the hull can be vertical sided, below the datum line, the hull is a semicircle with radius as in the table. Its basically a circular arc, formula of a circle is r^2 = x^2 +y^2
y = sqrt ( r^2 - y^2 ) - put this into a spreasheet and input R=1410 inches and you get this arc...

HULL WIDTH 13.50 INCHES TRANSOM WIDTH 10.96
STATION 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
0.75 1.64 2.61 3.48 4.25 4.92 5.48 5.94 6.30 6.55 6.70 6.76 6.70 6.55 6.30 5.94 5.48
