Shame he didn't have some kind of transponder on there, so he (or someone else) could trace where it was afterwards. With everything battened down, she should stay afloat for ages.

Having said that, single-handed sailing with no backup is a seriously dangerous business. Even two-handed sailing can be a problem if one gets in trouble and the other has to take over, because not all boats are designed to be operated easily by a single person.
