I'm sure anyone who gets a Super Sarca or Excel, will be happy with either - in a word they excel...sorry, got carried away a bit there...
But seriously, if you have a pulpit arrangement that rules out the roll bar, then the Excel is the way to go. If you would like one as a back-up, there is an alloy one that disassembles easily with minimal fuss, and because of the cunning way the shank slides through the fluke, it loses no strength by being able to be dismantled. However, unless you boat has the type of pulpit where the shank has to actually come aboard through a slot in the actual pulpit, then the roll bar is no issue. I works fine on any arrangement where the anchor shank comes up and over a roller, preferably, but not necessarily, hinge articulated, mounted at the end of the pulpit, or bowsprit, as it really should be called.
But there is something I love about looking out through the murk in a bit of nasty seaway and seeing that businesslike roll bar, proudly up the front, looking a bit like a large gun-sight, or a metal figurehead, and one that says, "don't mess with me, you'll come off second best". Not that I ram people mind, but if they were to come down on me...and knowing it will give me a good night's sleep when she hits the bottom in a suitable anchorage...bliss
Sorry got a bit carried away again there...but all the same, there is something really businesslike about it's somewhat agricultural appearance...yah just godda luvit..!
