The VY Sculptoris nova-like variable is a supersoft X-ray source during its optical low brightness state when the accretion disk has faded or is absent (Greiner et al. 1999, A\&A, 343, 183). By analogy, during the quiescence intervals of dwarf novae, when the accretion disk is in a cool state, hard X-ray emission is typically detected. The source of the V751 Cygni's soft X-ray emission remains a mystery but may be due to hydrogen shell burning, thus cementing a link between the VY Scl stars and the supersoft X-ray binaries. The archival far ultraviolet spectra of this key object have never been analyzed with realistic model accretion disks and photospheres to directly determine the accretion rate and white dwarf properties of the system. The orbital period is 0.144584 days, the inclination is low while the reddening is E(B-V) = 0.25 +/- 0.05 and the distance is 500 pc. We present the results of our multi-component model analysis and their implications for the relationship of this and other VY Scl stars to the supersoft sources.
