I agree, the jib does seem to be needed to tack correctly. I was sailing last weekend without it in 18-20 knot wind and and I could never tack. I had to do a 180 degree jive, if thats the correct term,(sorry still learning), to get the boat to point where I wanted. I would be interested in learning about jib blocks and/or converting to a roller furling system and getting rid of the jib stay all together. If I could figure out the jib problem I think I would be good, taking your suggestion of traveling out the main and fixing this jib problem.
