Close Hauled Tactics
You have not said what your problem with sailing close hauled actually is but here are a couple of quick suggestions. If you don''t have them add teletales on the end of your upper battens of your mainsail and on both sides of your jib roughly 15% back from the luff.
Practice at first by only focusing on the jib. Trim the jib in until the leech is just outboard of your spreaders and sail so that the teletales on the jib are flowing back horizontally. If one side is acting up or hanging down, turn the boat away from the side of the sail with the messed up teletale. In other words if the windward teletale is acting up turn away from the wind. Once you begin to get good at that trim in the mainsail so that the teletale on the upper batten pocket is streaming aft. If it is sucked in behind the sail or if when you sight up from below the boom the upper batten is cocked to windward of the boom, then ease the mainsheet just a little bit. If the mainsail is luffing at that point, bring the traveller to weather a little bit. With a big genoa it is not all that unusual to carry a small luff in the mainsail when going up wind in a breeze so don''t panic.
The main thing is to get out there and enjoy yourself. It will get easier with time.
