Parking in a cat is really not that easy. When bigger wind and waves are present you do need to continue to steer the boat otherwise you could tack and be blown over.
On my H20 I use to park all the time with the jib on the wrong side and the main and traveler all the way out. This worked fine up to about 12 knots. After 12 knots the force on the jib alone was enough to blow you over in a good puff.
The I20 I've found is impossible to park. There is a constant need to be attentive. The boat will tack suddenly and take off if you don't have the tiller in your hand.
The Tiger while easier to park still needs to be watched as it can also take off if it tacks. I'm not sure if this is somewhat due to the self-tacking jibs on these boats?
Anyway in my experience parking is a little tougher on the high performance boats than it use to be.
