As a first order calculation, one can assume the wetted area goes as the
2/3 power of the displacement volume (D). (D is weight in pounds
divided by 64). It is the friction of this wetted area that the sail
must compensate for. Thus on a racing yacht we might have A/D^2/3 ~ 22,
a cruiser ~12. You boat would be ~7 and very slow except in high winds.
These figues can be adjusted for form by the designer.

If a sailboat weighed 4960 pounds, and had a sail area of 120 square feet, would
it be fast or slow? Would it be considered over-canvased, or woefully
under-canvased? Are there any boats made that roughly fit this configuration?
Are they high performance boats?
