I'd second what Valiente has said. You're not heaving to...you're self-steering without keeping an adequate watch—which is a hazard to you and everyone around you.
If you really must take a nap—find a protected cove, drop the anchor and put up the daymark and turn on your anchor light. If you were in the middle of a trans-oceanic passage, doing this and napping for 15 minutes might be acceptable, but in crowded coastal waters, near land, it really isn't safe.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
