Fin arrangement for canted tower support

An apparatus, comprising:

• a starboard support configured to support an upper structure and comprising:
• a starboard strut comprising a starboard lower sleeve disposed at a lower end of the starboard strut;
• and a starboard lower fin configured to be secured to a common structure and configured to fit within and cooperate with the starboard lower sleeve to enable the starboard strut to pivot about a lower common axis of rotation at a starboard lower pivot joint;
• and
• a port support configured to support the upper structure and comprising:
• a port strut comprising a port lower sleeve disposed at a lower end of the port strut;
• and a port lower fin configured to be secured to the common structure and configured to fit within and cooperate with the port lower sleeve to enable the port strut to pivot about the lower common axis of rotation at a port lower pivot joint;
• wherein the starboard strut and the port strut are canted towards each other and when pivoting each maintains a respective cant angle that is less than 90° relative to the lower common axis of rotation.
