i would like to see a picture of how you have mounted the pad eye for that block/pulley and what kind you are using. At present I use a Harken that can rotate but some people mention a non rotating block.
I personally use swivel blocks as well, but am careful to remove any bias from the sheet before going out. Because of the possibility of binding the sheet, standard blocks are a safer bet and recommended by Hobie. Standard blocks can pinch the sheet against the deck however if oriented improperly so it pays to test everything before setting off.
Moving the block forward tightens the leech and flattens the sail. IMO, this gives better control in higher winds and reduces the whipping action on jibes. Here's a look at the sail shape with the block moved forward:
In determining the best location, I rigged an adjustable "eyelet" that I could control from the cockpit. It also served as a traveler (which had negligible effect):
I settled on this location and am very pleased with it.
My friend in the picture from my previous post uses a similar set-up, but with the padeye just inside the cargo well (to maintain a flat deck). Note, he also uses a non swiveling block -- it works well in that location:
You can stiffen the mast by inserting a dowel or bamboo stick. This reduces whipping but can add more stress to the hull. I haven't tried it, but those who have seem to like it. Where I usually sail, we can get sudden gusts from odd directions off the mountains, so I like the mast flexible to act as a safety valve.
