I can't seem to tack without stalling almost every time.
Your tacking issue will be related to speed through the tack. A cat can not pivot on a center point like a mono hull. The two hulls track straight and drag more through turns. Tacking from a reach will cause the boat to slow too much before it gets head-to-wind. You need to round up to a higher angle of sail before jamming the rudder hard over.
Round up slowly and sheet in. Sail at a "close hauled" angle, with speed. Start the tack by steering slowly into it. Steering hard is like putting on the brakes. As the boat goes head to wind and slows, steer harder over and then sheet out the main once the sail luffs. Keep the jib cleated and let it back-wind the bow through the tack. This lets the bow cross onto the next tack. A sheeted main will "weather vane" the boat into the wind. So force the main out several feet. Let the bow get well past the next tack angle and then release the jinb and re-sheet on the next tack, then sheet in the main slowly.
