Thanks Ric,   I was planning to use packing -type straps to the stern rail to provide some lateral reinforcement.  I'm hoping to come up with a design that will fold into a relatively small package when not in use.  I will ponder your council and perhaps consider a different design.

 The lintels can probably handle the compressive loads but without added connections to the stern rail would most likely fail to handle the lateral loads of the mast and sliding it forward and or aft. I would mount it on the stern and lash it to the stern rail, the way GB designed it. It’s simple , direct and easy.
