The bark carrying the shrine on this relief is not a solar boat, but a "lunar boat," because the falcon-headed deity crowned with a disk and crescent is Khonsu, whose name is written in the hieroglyphic caption.  

Khonsu is a moon-god whose name is understood as the "traveler" or "wanderer."  He is the son of Amun and Mut, and together they form the "Theban triad."  The disk is a lunar disk, which is typical when it appears along with the crescent.  Together, the different phases of the moon are represented.  He is represented either as a child or youth with a sidelock, or as a falcon-headed man crowned with the disk and crescent.  Khonsu is also known as a potent exorcist or driver-out and vanquisher of demons, as described in the story inscribed on the "Bentresh Stela."

In the present relief, the boat bears the shrine containing the image of the deity.  It has carrying poles and is carried by priests in religious processions. Here it is set down on a pedestal or plinth which is a way-station on the route of the procession.
