New Boat; need a few things

Hello all! We have purchased hull 1251. It is our second J24. Solid boat with vermiculite removed. Hoping to join in some OD at some point. Looking for a Winter deck cover. I like the ones that allow you to leave stantions up. Any recommendations for or against this style? Anyone have a used one they are willing to part with? Will also be looking for a Genoa before next Spring. One for racing and maybe an old Dacron for day sailing/ practice. Located 10 min from Detroit in LaSalle ON Canada.
