Re: I can't heave to
The best instructions IMO, on heaving to, and most sailing things, can be found in an inexpensive little book called Royce's Sailing Illustrated.
I've used it since the sixties and have it available for all who sail with me read it if they wish to learn about sailing, boats, rigs and simple navigation.
