Re: How do you heave to with main sail alone?
On small cat rigged (one sail) dinghies, the instruction is usually to put everything to leeward. So, on a port tack let the sail luff, when speed has dropped to almost zero start pulling the tiller to leeward, and put your body weight on the leeward rail. The rudder and hull balance will both tend to make the boat head up, the mostly luffing sail will tend to make the bow fall off. This is more of a 'resting position', rather than hove-to.
