It would be possible to tack with a spacecraft capable of using the solar
wind....

Be a man. Admit your foolish error. Further Ganz bashing only
demonstrates
your frustration - not your manliness.
Stand Down.... I've made no error!
If I recall correctly you were alluding to tacking through a Solar Wind...
which would outline your proficiency in the subject you've only recently
researched by utilizing Ganz's links!
Here let me quote you brainiac..
Bwaahahhahahahahahhahhahha. That solar sail will work but
only downwind or crosswind. It will never be able to go upwind.
It is against the known laws of physics for a sailboat to sail
directly into the wind and it's the same for solar sails
Cross Wind????? ... on a photon wave?? Solar Wind..... Pffft!
.....and since when are you placing limits to tormenting Ganz?
