CALCULATION NOTE
Introduction This calculation note describes the calculation of the B-60 and B-100 freeboards of the Yacht Carrier. The freeboard calculation is according to the International Convention on Load Lines (1996). The freeboard calculation and the calculation of the hydrostatic particulars are performed with the computer program GHS by Creative Systems. The main dimensions are according to drawing: general arrangement yacht carrier. Ref no. R0401 rev 12 Damage stability calculations will prove whether the B-60 and/or the B100 freeboard may be applied. Main particulars Length waterline at 85% Depth Length over all: Breadth (mld): Depth (mld): Design draught: Thickness of main deck plating 197.559m 209.030m 32.200m 8.500m 5.800m 0.020m

Freeboard calculation Yacht carrier
This sheet calculates the B-60 and B-100 freeboards of the Dockwise Yacht Carrier according to the International Convention on Load Lines (LL 1966). The vessel dimensions are according to general arrangement: RD0401 The hydrostatic properties are determined with the GHS model of the YC made by Dockwise.
