Generalized regional model of risk. Risk calculated for the 101 Boat in the region combining key motion of heave, pitch, and roll. Risk is defined as the ration of predicted heave to 30% of the boat's length (low risk, heave <15% of boat length; medium risk: 15% of boat length ≤ heave <30% of boat length; high risk, heave ≥30% of boat length).
