Nice wheels!
Those are all really nice!
What I’ve seen on a lot of boats is section wrapped UV resistant synthetic ‘twisted three strand twine’. Generally in white.
They have either done the wrap knotted with a rolling half hitch that spirals around the rim or as simple winding wrap sections tied off at each spoke ( I assume to minimize the risk of it all coming undone should a strand break or unknot). I’ve also seen an examples where it has been two, three, four, five and six string braided in various colors that look amazing!
Well beyond my personal attention span nimble finger dexterity capacity!
Kudos to those that have made this effort!
They all look fantastic!
