I. Calculate H
Calculate H, (for later comparison against N, see Figure 3-9). The value H is the height of the far bank at
the F peg relative to a baseline which is drawn through the RB and 0 pegs. The baseline extends from behind
the 0 peg on the near bank to a point beyond the F peg on the far bank.
(a) For push launch.
(b) For jack launch
H = Elev F + Elev 0 x (.L + 0.23 m)
H = Elev F + Elev 0 x (L - 0.23 m)
