Keep the folding prop, your boat will perform much better as a sailboat than with the fixed prop. The lost of power is maybe 10%.
If you ever have to go against 2-4 kn current for 32-40 miles in a 30 foot sailboat, stay home. FWIW one way to duck the currents where the shore line permits, is get into shallow water along the shore where the current dies out...
