I'm not sure where you're sailing, but from my experience one can sail engineless w/o an engine, with an engine, any time one pleases. However, consider the cons if you are a day sailor with a home port. You are 1/2 a mile from your home port (marina, mooring, etc) when the wind kicks up from where you want to go. Under sail, it would be quite difficult and time consuming to make your home port, especially in a narrow channel. Perhaps you have the free time and patience of Donald Street, but more likely dinner's on the table at home. Sure, you can anchor in place, but quite often these types of weather changes are related to moving fronts which may take days to move on.
As a cruiser, we did over 2k miles one season in the eastern Caribbean using the engine less than 20 hours. No long ocean crossings, sails limited to a max of around 80 miles between islands from St.T to Trinidad. If you have the time and energy, and trust me it takes lots of both, to sail the lee of the eastern Caribbean, then who needs an engine? But many of those lees are 20 miles long or more and that means sailing every puff, though you can do numerous 360s to achieve your goal. Never mind the currents running along the islands.
Also, we had a grand sailing vessel (53') and after hours and hours in the lees, she'd power her way across the next channel at 7 to 9 knots or more, which meant we could make our destination before dark, even without using the engine at all on the trip.
Watermakers are the greatest change for sailors, but I'd put the safety of your life and boat after one, not instead of one.
