Not that I am trying to sell you something, but I highly recommend your getting the new video "Upwind & Rolltacking" for cats. Check it out at Catsailors OnLineMarineStore.., Books & Videos
Nothing against the advice you have been given, but most of it is stuff we USED to use, that does not work well these days.
We USED to backwind the jib, stop and back the boat up, reverse the rudders, and finally get under way. That is why all the monohull folks laughed at us. It USED to take 20 to 40 seconds to tack a boat. That equates to about a boat length per second, or 20 to 40 boat lengths.
Now, we know to sail the jib through the turn and keep the boat moving.., now we don't stop the boat and are back up to high speed in about 4 seconds.

By the way, the idea of backwinding the jib (leaving it cleated) in heavy conditions is a good way to flip the boat over backward.

Jibing is much more dangerous than tacking in heavy air. Although, tacking with the jib cleated, as mentioned above, is also dangerous. I was in a distance race that had the winds really howling and had a comfortable lead on some young and crazy sailors that were in second spot.
If we capsized, they would probably win. It was a downwind race, so we dumped the sails (so we would not capsize during the transition from downwind thru reach to close hauled)+, headed up, sheeted in and tacked.
My crew called me "chicken" but we won the race.

Good luck,
