An apparatus includes a bendable elongated assembly extendable over a watercraft. A coupler assembly is configured to couple the bendable elongated assembly to the watercraft. An engagement assembly configured to engage the bendable elongated assembly. This is done in such a way that the engagement assembly, in use, urges the bendable elongated assembly to bend and form an arched structure positioned over the watercraft once the bendable elongated assembly is extended over the watercraft and is coupled to the watercraft.
