Hi Todd,
Wouldn't it have been great if the rudder system on your boat had come with the modifications you had to make to get it to work right in the first place? Wouldn't that have been wonderful!
Here's another benefit of the SC/ARC rudder system. If you need to sail out through the surf with the rudder part way down, half down for example. Pull the green line until the rudder blade is in the part way down position desired. Fold the green line around the end of the tiller and place it under your hand which is holding/steering the boat. The two abrupt 90 degree bends at the end of the tiller as the green line does a U turn at the end of the tiller will act as a temporary cleat while you are sailing out through the surf or across shallow water.
Good Sailing,
Bill

Yes Bill,

Without a doubt, the standard Nacra system, is in my opinion sub par, dangerous. As far as going over shallows, and with good bungees, you loose all your steering. And when the bungees get worn, backing the boat on catwheels often has the rudders folding under, or snapping off if you're not careful.

The simple mods though, allow sailing in shallows, as you describe. Yes the SC system is nice.
