In the drawing the vertical line above hull represent the rotation of leeward hull due to either sail induced heeling or improperly aligned hulls. I can show incremental heel angle on paint for any unless I draw each one. Still referring to Blind Date and its smallish looking leehull.
Put a up another diagram in same folder see both set at vertical static positions no induced preset canting. Each are set as loaded ready for sailing.
Each leeward hull in diagram will have a different canted angle when under sail heeling loads while sailing at same speed.
When at desired speed range say 16 knots the force exerted on leeward hull requires buoyancy to restrict further sinking/squatting to reduce further canting of hull to maintain optimum performance. If you are already at max canted angle due to low buoyancy or misaligned hulls then performance of hull/boat will suffer.
