So, you appreciate that it's possible to sail a boat without having
lifelines fitted, and to have a good chance of surviving the experience.

So long as you can swim. Flipping a dinghy is part of the fun, especially in
heavy air when you push the limits. For your little boat? A simple harness is
more than enough and I doubt you'd use it much, unless you want to be a safety
suzzie when singlehanding. My biggest concern with your boat would be a
knockdown, which can happen with those little pokey cruisers. Make sure her
cockpit storage is fixed shut and hatchboards are secure in heavy air.
Now stop it!
