Dear Robert,
I am sorry to reply so late but I have been away a lot for my space
work. Not much time for anything else.

If you wish to have the lower part of the sail with seams starting from
the tack then you can use the twist foot layout option.

If the twist foot is not what you are looking for and you have another
layout of panels in mind I would appreciate a sketch to visualise what
scheme you have in mind.
