Try the "Temporary" fix
I have a 1983 H-30 and previously had a 1978 H-27. Both boats have the same problem are your vessel. The mooring lines wear away the edge of the black fiberglass stem cap leaving a raw edge that does a great job of sawing through mooring lines.
On both of my boats I removed the chocks and made up an triangular (with rounded edges) stem cap out of a 3/4" oak boards glued together. It was about 3/4" larger than the deck area so it would lap over the edge of the bow. I had to cut out a section in the front of the stem fitting to allow the new cap to fit around the strap and fittings for the front shroud line and roller furling drum. I then put a 3/4" x 3/4" edge on the under side of the new stem cap.
I rounded all of the edges of the new wood cap and sanded and sealed with about 4 coats of teak colored Cetol. I put the cap in place with some caulking (4200 I think) and used linger screws on the chocks to hold the unit in place. I've had no problems with it other than the a split in the cap which I will probably fix this winger but it does not affect the functionality.
This was supposed to be temporary while I had a stainless or aluminum cap fabricated. I sold my H-27 before I made the switch and it's been 5 years on my H-30. But it's on the list.
If you look at the library of posts I think I posted a picture of my "Ttemporary" solution.
