First responders treated an unresponsive windsurfer about 250 yards off Kawaikui Beach Park in Wailupe Saturday afternoon.

Honolulu Ocean Safety lifeguards responded to the 59-year-old man just before 5 p.m. after a group of canoe paddlers saw a man “in distress” and kept him afloat, according to a Honolulu Emergency Medical Services report.

Lifeguards brought the man back to shore by jet ski, where they gave him CPR. EMS said paramedics took over the patient’s care, providing him with advanced life support before taking him to an emergency room in critical condition.
