Hull Variation H4a

Created a sail plan for H4.

Ran the hydrostatics report on H4 and found that the sailing displacements at HCWL=-20, HCWL=0 and HCWL=20 were higher than anticipated. Adjusted the design slightly to fit the following sailing weights:

HCWL mmTarget DSPLDesign DSPLPurpose
-20285kg304Singlehanded
0385kg374Doublehanded or singlehanded with camping gear
20485kg450Doublehanded with camping gear
