We are talking two things here. Tethers and chicken lines. Tethers keep you attached in the worst case situations and chicken lines keep you in control when sailing out of control. A chicken line system requires that the bitter end be tied off to the stern of the boat for the captain has enough leverage to use the line to counter forward momentum. Through beam does not work. In addition, it needs to be retractable. The best chicken line systen on a Nacra 6.0 I have seen is quite simple. You need 2, 10 foot pieces of 5/16 line. Tie the line to the rubber pin with a bow line, then run the line along side the boat. Attach a bungie cord to the line. feed the bungie through the crews trapezee groumet in the trampoline and repeat on the other side. Adjust to tension system. This will give plenty of security to the captain and crew for forward motion whenever you go submarine.



Tethers are a separate subject. I recommend a system that is center trampoline based. This eliminates the needs to uncleat and cleat. Rick White interviewed John Tomko of Team San Antoinio during this years Worrell and he describes this system. If you want a separate system, use the beam system with lots of bungie and blocks. Still have to remember to hook up after each tack and sometimes this can be hard to do when it is blowing 25 and the boat is flying.



By the way on Inter-20's you cannot tie off to the rudder because they do not have full length pins. On these boats you do need to put an eyestrap on the stern. An eye strap with good through bolts will hold all the weight you give it. If you pull off the stern then you fix it but iI don't believe this will happen. If you put that much force on it. the boat will just move and the energy disipated (sp?). Now if the boat was tied down then you may tear off the stern.



good luck.
