On my c320 I ran the traveler control
lines outside of my dodger and back to the stern pulpit so that my wife could relax against the bulkhead in peace as I basically single hand 99% of the time. I simply used rail
cleats to hold the block on the cabin top and block/cleat combo on the forward rear pulpit rail. It may look 'micky mouse' but it worked perfectly for 4 years up until I traded it in.
