Well, if you should ever leave the benign environs of Sydney
, and go cruising to distant places, you may find that there are places where you will be compelled to lie alongside some pretty rough walls, wharves or docks. Then you will see the beauty of a stout rubbing strake, whether in a cat or a mono.
It is a fact, though, that few modern designs of either type feature such helpful bits. They are not particularly aesthetic, and they add cost, but by golly there are times when they are a godsend.
It can be accomplished in some designs, though. Our boat, and quite a few other semi-modern shapes, is widest at the deck level. Our perforated aluminium toe rail incorporates an external rounded rib
that runs the length of the hull
, and provides at least a modicum of protection. Not as good as a teak
4x4 that some more traditional hulls sport, but a lot better than grinding glass/timber/paint or whatever against the rough concrete of a foreign customs
wharf! Careful fendering can reduce the need for such strakes, but being human (barely) I've found myself "underfendered" in far too many places and been glad of the added protection from the rails.
The hull profile of many cats that I have seen does not lend itself to that solution, but it could work on some...
