An '85 should be a MK-II. The hull is #862 of the production run; mfr'd in Jan of 85 (based on your HIN). The rig type would depend on what the standard or tall dimension is; measure your mast height and boom length. The "S" should denote a shoal draft configuration; but I'm not certain on that one because my boat is labeled on the instrument panel as a '41-S but it has a full depth keel.
