A multi-hull variable aspect surf rescue boat is provided, which can support and contain occupant(s) and cargo and can be readjusted in shape and size to vary the boat's length overall (LOA), beam on center (BOC), the LOA/BOC ratio or OAR, thereby changing the boat's attitude, center of buoyancy and center of gravity without changing the boat's components or weight. The boat includes a frame assembly comprised of a centerline tube and three or more radiating, extendable and retractable telescoping tubes which intersect at a center line of the boat. A respective starling control assembly is attached to each telescoping tube, providing buoyancy to the boat. The frame assembly carries a platform for carrying the occupant(s) and cargo, and a means of propulsion for transporting the boat in surf or turbulent waterways.
