We had the same problem when we bought this boat
... our first with a nearly plumb bow. Our first response was to have a stainless shield made that was a close fit to the bow profile. Cost a bunch but looked quite smart... until the dents started appearing. Seems that the edges of the anchor
(Manson Supreme) were small enough to put pretty big spot loads on t he s/s, and dents kept proliferating, and it looked pretty daggy.
Replaced it with a PVC matting material, about 6 mm thick, similar in colour to the hull
. Stuff was allegedly fairly UV resistant, soft enough to absorb the blows without marking, fairly inexpensive and easy to install. Quite unobtrusive, too! This is now around 10 years old. It has some minor staining and the surface is getting a few small cracks, likely UV damage, but it is still completely functional. I'm quite happy with this solution.
