Good idea, but I don't think the numbers work out. To brake a
15,000 ton ship from 0.02 c in less than a decade, I need 63
tons of magsail thrust -- more than 10,000 tons of sail. That
mass is better spent on reaction mass for the existing drives.
Magsail thrust is dependent on velocity relative to the medium being
pushed against, and on the density of the medium; the 63 ton figure is
for a medium at the velocity and density of the solar wind. Naturally,
this isn't covered in Vehicles.
This will be a general issue with the entire project: Vehicles isn't
really intended for this sort of application, and thus the numbers it
produces will be questionable at best.
