Mary-
You would have to rig up a different up/downhaul mechanism on your Taipan. One solution that might work is a modification of the system often retrofitted to N 5.8/6.0's that I employed on my old "A" cat. I had a bunji uphaul and rigged a line downhual. The rudder downhaul line ended in the front of the rudder in a "cutout" ala the Nacras then ran under a bolt in the rudder housing, up over another bolt at the top of the housing under the tiller arm and ended in a microblock. Then a second line ran from the back of the rear beam, through the microblock, and back to a cheekblock mounted atop the rearbeam (on the Taipan this line would have to run through the rear beam then through a throughdeck block in the front of the rear beam or through a microblock/cheekblock mounted under the inside of the rear beam- If you choose the under beam mounting location then the end of this line needs to be from the outside of the rear beam) and then towards the midline of the boat along the rearbeam to a releasing camcleat (made for dinghy rudders- it releases upon impact and is adjustable) and then I ran it through a plastic line guide (so simply pulling it on the other side of the line guide would cleat it). The line was continuous between sides and I used small Spectra lines. The rudder could be released by merely uncleating from the cam cleat (you did have to go to the middle of the boat in my case but you could mount the cleat wherever) and then quickly pulling the line down.
Remember though- you really do NOT want the rudders "loaded" when they are part way up or down regardless or you will break/bend/tear up either the transom pins, rudder case and/or rudders so regardless you will have to at least slow down and ease sails during the process.

Hope this might help-
