Dan,
I've taken a couple Hobie's apart and they didn't go too bad. Remove the tramp and pylon bolts and use a rubber mallet, or a block of wood with a hammer to remove the corner castings. Often times they are stubborn to remove unless you have the hull in perfect alignment. If the casting is binding when you try to remove it, it's going to cause you fits. Just wiggle the hull up and down / side to side until you find the loosest position. Hope that makes sense.
