2. Stations and waterlines
Station profiles for stations 15 - 20
First, each station and waterline was drawn separately to
ensure a smooth line. Next they were drawn together, as
per the finished product of a naval architect, to make sure
that they were correctly separated, one from the other.
A table of offsets was prepared from these drawings
D. Calculation of the ballast
I wanted MS II to float on the same lines as Michel Selig. In
fact, this was necessary for MS II to conform to the Rule.
Henry Farley said that the only way to determine the weight and
position of the lead ballast would be through trial and error. He
advised me to build the lower portion of the hull (the "plug")
detached from the upper portion - and also to build several
copies of it for the trial and error process. The plug would be
connected to the upper portion of the hull by two lengths of
threaded stock which would also connect the ballast keel to the
hull.
In fact, the plug didn't run fully aft. I fabricated a fixed
sternpost for the after portion. This would permit me to build
the rudder and its radio control independently of the task of
fabricating the plug..
