W
estlawn Institutehas introduced the secondnew text-
book in threemonths. Thisnew text is
Principles of
Resistance
,Westlawnbook105a. It is part ofWestlawn’s
Yacht&Boat DesignProgram inModule1, andalso inWest-
lawn’s Elements of Technical Boat Design short course. The
newPrinciples of ResistanceBook105a, replaces theprevi-
ous versionof this text andnot only completely updates the
previousmaterial, but ads exten-
sivenewmaterial,more than tri-
pling the content and scopeof the
previousmaterial.
Principles of Resistance
now cov-
ers not only the fundamental prin-
ciples underlying resistanceof
boats, but now includes reviews of
theReynoldsnumber, fundamen-
tals of direct calculationof resis-
tance, principles of tank testing,
andpractical speedandpowering
calculations for all types of boats.
