The bow portion of a sailbaord is insertable into a pocket at the underside of an inflatable delta-shaped hull having a width exceeding that of the sailboard. This results in a boat which is capable of supporting several persons. The stern portion of the sailbaord can be strapped to the stern of the hull if friction between the surface surrounding the pocket and the surface of inserted bow portion of the sailboard does not suffice to reliably couple the sailboard to the hull. The hull is assembled of or includes several longitudinally extending tubes defining gas-receiving chambers or serving to receive inflatable inner tubes. The hull can be provided with openings for a mast, which can be rigged to the hull, and for a pivotable keel of the sailboard. The hull can also carry a delta wing and an engine for an airscrew if the combination of hull and sailboard is to be used as part of an ultralight aircraft.
