Re: What are the benefits of a self tacking jib?

Mac,
The Aquarius curved jib track, curved more outboard, straight in the central area, will encourage the jib to run further outboard when tacking downwind "without spin". With spin the jib is always trimmed closer to center. It is like sailing to windward with a slight ease. Just trim the jib to the tell tales and everything will be fine on all pointa of sail. With spin, the curved jibtrack isn't necessary because the jib is never very far off center. It is not that one is better than the other. With spin you don't need the curved track. So, the whole beach cat world, newer boats with spins, don't know what in the hell they are doing with curved jib tracks. It, the curve, is useless and requires an additional jib car control line to set the position of the car along the fulley curved track. The jib car position changes with wind strength and point of sail; something else for the crew to do if the crew knows what to do. The straight track, or Aquarius curved jib track with a straight central area, does all of this for you automatically. The car even moves out slightly with puffs and back in after the puff passes. In a puff the relative wind clocks to windward slightly and the slot, jib to main, needs to be wider for the higher velocity airflow. The SC/Aquarius self tacking jib system does all of this for you automatically. Non of the other fully curved jib tracks do this. Why won't the beach cat sailing public buy boats built by Aquarius??????????
