It seems your premise not to adjust the halyard is faulty. With appropriate headstay sag, it is a very important contol for headsail fullness, which is what you want in light conditions. Wrinkles can be your friend. Lead position is also critical. On our boat in light air, point is best when the foot is fairly far outboard, almost touching the lifelines.

Since you say you can point with most of your competitors save that "one" that is higher and faster, I would suggest that you do not chase him up to the detriment of your own boatspeed. Put the bow down and sail fast.
