Good info above from
@Crazy Dave Condon,
@Joe, and
@sail sfbay on the issue of lifeline replacemen.
Scanning the web‘s images of Hunter19 boats, there are boats with “lifelines” and boats without. Perhaps they are not needed?
If you race your boat it would be wise to check if the rules require specific life line standards. Rules in my area require SS or Dyneema like like. Dyneema line must be inspected for chafe yearly and replaced every 6 years.
I would not use coated wire as lifelines. It has proven yo be problematic. Water gets under the coating. In the absence of air this is a formula for corrosion. The SS or common wire used rusts and crew go overboard.
SS is not too expensive. I used SS wire in the refit of my 35ft boat. Cost $660. I used the benefit of machine swaged fittings. When professionally done you get a better crimp on the wire. If this is not an emergency get a couple of quotes during the coming off season.
For your boat I think the Dyneema method would be the way I would go. The cost is in the new fittings you will need. The fittings must be compatible with Dyneem. The Dyneema material is lighter weight than SS. You need to learn a little bit about knot tying and splicing but it is useful knowledge to have for your current and future sailing.
That is my perspective. Enjoy your boat and write up your experience.
