If you leave the turnbuckles at an athwartships position, and the cotter pins facing aft, you will rarely get caught when going by. Roger Long, IIRC, also posted a picture of how he does his, by cutting the ends down pretty short and only turning one of them. There are all sorts of ways to deal with the "issue" without covering them up, which has proven over the years to be a not so good idea. I've spent the past year without any pins at all!!!! [Insert GASP
here!!!] Really. I just leave them (the upper and lower shrouds, not backstay or forestay) all facing a certain way and it takes months for them to move at all. Pretty noticeable when if they all face fore&aft and one starts to move. Also makes it quite easy to adjust them. I use my boat weekly and am down at the boat more than that, so I'm on top of it. Wouldn't recommend it to folks who don't get to do regular inspections.
