It's oblivious that this kind of tack would be an electrical tack.  The "keel" would be the current generated by the collector sail.  That current can be steered and orientated, giving you an electric keel.  Three currents give three axis.

Solar wind is an accelerating two pole DC current.  Could one possibly ask for a better corridor?

The sail is not pushed or pulled or blown against.  The sail(s) collect charge.  The current generated produces a field, that current field reacts with the solar wind field.  The wind is one current.  We produce another current to scissor with it.  The proper polarity and orientation of the produced current field, should allow acceleration in any direction.  And area might replace high current demand predictions.

The sail might be a large concentric circular structure, funneling charge to the proper polarity receptor.  Two polarity collectors.  These "sail" collectors will be new inventions. They also have to be switched into a shielding or repulsive mode.  Just one storm will kill all aboard.
