Fell in love with mid-ship cleats when sailing with a cantankerous engine. Mid-ship cleats took the stress out of dead engine docking. In one memorable docking with a small-craft wind blowing me out of slip, the mid-ship cleat saved my butt.
The book Stress Free Sailing by Duncan Wells has pages of illustrations using mid-ship cleats for docking and getting underway.
Having an extra tie point sure feels good when the occasional gale blows in. Nothing like having a dock line chafe to the last strand to appreciate additional lines.
I sail pretty much every week, and yes a few times a year a jib sheet gets caught. Mostly because the crew - me - got sloppy. Easy to clear. The spin sheet never has been caught.
I used to use it as a preventer tie point. Only good in light wind, as the forces are too great at the angle of boom to mid-ship cleat to be safe on any sizeable wind. MorganCloud's blog has a convincing article on this point.
