You're on the right track.
If I remember correctly, the Bayfields have an aluminum perforated toerail around the deck edge (gunwales - pronounced gunnels) If you have blocks on board that have snap shackles attached (openable connectors) they were probably mounted through the holes in the toerail. The toerail design allows you to attach these blocks where ever you need them to be. As mentioned in a previous post, for your Genoa this location could well be aft of the winch.
You should probably figure out how to properly use this sail; in light conditions you'll appreciate having the extra sail area. However if it's a "170%" genoa - oversized as compared to the usual 150% -it may not be worth the hassle, assuming the 150 is what's on the furler.
you can check that by measuring the distance from the clew (where the sheets attach) through to the luff at right angles to the luff (leading) edge. Compare that measurement to your "J" (distance from the forestay to the base of the mast). If your J measurement is, say, 10 feet, then a 150% genoa would measure 15 feet as described above.
