Also went to Ask.com "How long to search for person lost at sea".
This does tie in with the question I asked the other day.
A person is reported missing for at least 48 hours. Shortly thereafter, his sailboat is found drifting at sea, no one onboard about 3-4 miles from shore. It's June in New England. The weather's been decent.
How long will they conduct a search for survivors/remains?
ETA: Thanks, everyone! I appreciate the help!
