We had 4 Allen Swivel cleats on the mast this year. Kicker, cunno, T foil and Jib.
Pro's
-Crew or helm can adjust either from the wire, accessed by the end of the main (sucked forward and tidied by elastic)
-Pulling more on, the cleats auto cleat around the kicker when on port (conventional diagonal strop, means the ropes have to pass around it)
-Letting off is actually very easy (you move your hand further up and the rope slides up the kicker and uncleats)
- NO FRICTION - what you pull is what goes into the kicker etc
- Eyes always forward and out of the boat.
Cons
- If helm adjusts jib when crew is comatosed in bottom of boat, then decapitation is possible
Will post some photos next week - when I hope Rossa is on the water again
