I recently purchased a used 170 and have virtually no prior sailing experience. I sail on the Magothy River which is a tributary of the Chesapeake Bay and can experience 12-24" chop. My first two outings were in 10-15 knot winds and that combined with the chop scared me and my first two, never to return, passengers. My questions are, one, can any ballast be added to the center board or hull to help stabilize it, two, if it tips over will it promptly turn turtle, and three, what is the procedure necessary to get it upright if it does go over? I would appreciate any comments from experienced 170 sailers.
