Note: The actual rake of the mast depends on the mast step position and how the mast is set in the deck partners. Potential rake assumes the mast is at PMax (which can be at or behind the aft edge of the partners). Potential rake is limited by Rule IV 5.11 to maximum of 2.00°.
R = Rake
Ym = Back of aft coaming to aft of mast at deck
X = Back of aft coaming to aft of mast at step
B = Bury (Deck to seating surface of mast step)
