I'm not sure I understand. What is the risk, and what is the alternative?
It seems to me that a cruising
boat has to have some way to cleat off the mainsheet. There are conditions where you want the sheet in your hand, and there are conditions where it is safe to cleat it off and read a book. Taking the sheet off a self tailer may be easier and faster than clearing a heavily loaded
rope clutch, but it seems like having both available leaves the choice up to the sailor's judgement and the conditions.
I was recently on a Nautitech 40, which has both the double-ended mainsheet and the jibsheets led to the same pair of winches, with
rope clutches. Now that, I thought, was dangerous. When tacking there wasn't much alternative to cleating off both ends of the mainsheet to free up the winches for the
jib sheets. That just didn't seem safe to me in windy or gusty conditions. The Nautitech is almost exactly the same dimensions as the Spirited 380 with a rig about 10% smaller.
