2 pieces of PVC, 1/2" will do
2 bolts with wingnuts
foam noodles or pipe insulation to cover the PVC and protect the gelcoat.

Cut the PVC to appropriate length, it will probably sit at an angle of 30 degrees
drill holes in one end of PVC pieces
bolt the PVC together
slide on noodles or insulation
place on tail and determine where to drill holes for the rear bolt
buy extra noodles or insulation as they will deteriorate quickly in the HOT sun

Two noodles alone would already provide some stiffness.
