All U Get: Here's my suggestion regarding the internal outhaul system on your 1981 C30, which I also owned - GET RID OF IT - and here's why. First, it is a poorly designed system. The problem is with the internal swivel block, which is is the culprit with the system. It twists and then binds no mattter how many times you fix it. The result is most older C30's have the outhaul stuck in some position which makes it like the broken clock. The setting is right for some point of sail and wind condition and wrong for all other. The outhaul is the primary sail trim control for draft depth. Draft depth is your accelerator and you don't have one at this time.
That is just the start of the problem. Next time you're at your boat crank on the outhaul and watch what happens to the slug in the track. When you crank on the outhaul, because of the pulling motion of the line, which is downward, the slug digs into the boom creating unwanted friction. Eliminating the slug is not the answer. Without the slug the clew will dig in
The solution is to install a system that results in a horizontal pulling motion. How does one do that? Simple, I installed two small Harken triple blocks, which are expensive little buggers, but they works. Drop me a note at

My system is not the best fix. A friend of mine, Max Munger (C30 National officier) designed a better one. He installed a small track on the boom and had Garhauer build a small car to ride on the track. In addition you have to have the foot of the sail cut to allow the system to work. My system is the poor man's approach!! Max is richer than me!!
Another solution is a loose footed main. The problem with that system is most sailors induce too much draft depth (belly) into the sail, which is counter productive.
As far as telltales on the jib - your set in the middle of the sail are fine but you need another set at the top portion for twist. If you want to skip a set then do so with the bottom set.
