Like many C30 owners I have been struggling with a balky main halyard on my boat acquired about 6 months ago. I have the original lead back to the cockpit configuration, and it's been a bear to hoist. Opinions have differed about the cause, most seem to think it is in the sail slides. I believe I have come up with a cause and result, at least for my 88 boat. First, I attached a good block to the main halyard and hoisted it to the top of the mast with a second halyard in it. I then hoisted the main with this "new' halyard, and it goes all the way up with ease, a strong child could hoist it. It also drops like a shot. Conclusion---it's definately not the sail track or slides. Since nothing can be done with the pulley in the mast head[assuming it has been checked and is turning freely], then the remedy has to be in the lower turning blocks. Both of these are plain shieves working on a dry metal pin, a lot of resistance is inherent even in a new unit, and years of wear don't help. First for a remedy, I cut an exit hole about seven feet up the mast, and fished through the main halyard. The first test proved the remedy was working. The main goes up and down freely when hauled directly from the exit hole proving that the mast head pulley is OK. Now to get the lead back to the cockpit and use the original halyard leads and winch, otherwise a winch would need to be installed on the mast. I fastened a small padeye to the base of the mast and installed a ballbearing pulley on a swivel and went directly back to the winch and avoided the old deck turning block. The sail now goes up without binding, much easier than before. However, because of the resistance of the lead back and the clutch, there is still some difficulty, over a direct pull from the mast, but very workable for this 70 something sailor. What I have tried that seems to work OK is to pull the sail up from the mast[with ease]tie a slip knot in the spinaker pole eye, go back to the cockpit, give the halyard a jerk to free it, then finish the tension with the winch. Now I have the main under normal control in the cockpit fot reefing and or dumping. My object was to simplify the the process for single handling, reduce the effort needed and keep it safe. Feel free to to inquire if I can add anything more. Good sailing Ron B
