I don't think the monohulls park because it takes so much effort to get them up to speed again.
Why would that matter if they are just waiting around between races?
You know? I do race my Hunter 23 from time to time and we don't ever try to park it. Perhaps I'll try - but the boat is so easy to sail that it's not really a big deal to keep moving about. Secondly, I suspect that it will handle so poorly when it's not moving that it won't be very controllable.
