Mainsail headboard car HS22.160R

It’s a head carriage with automatic hook (MOD. HS22.160R), which hooks onto special stops (MOD. HS22.17) on the mast track to unload the halyard. Two manoeuvres from the mini hook go down along the sail: to disengage the hook and the carriage is free to lower and to load the hook, which hooks onto the first stop on the track.
