== Inform Coast Guard so that rescue will not be started.
-- Be in radio contact with Coast Guard to inform them in case public calls in.
"Rescue is NOT needed; hang glider deliberately landed in ocean and is converting itself to small water-sailing vessel. All is good."
==Release time? Some systems may have the pilot release into water before landing; then swim over to wing to reconfigure it. Perhaps have long leash so wing does not blow away. Or flare and land with triggering floats; but be ready for full release of pilot as needed.
== Know thy weather and sea state!
== Buddy system.
== Non-corrosive materials in total system.
== Have drinking water maker ready.
== Have food ready.
== Have fishing gear?
== Self-tow in ambient wind for rising again into air; use spoilable water-chute anchor to brace for the ambient-wind kiting to altitude. Then spoil the water chute anchor and pull it up to flying affair.
Anyone may continue the technology and share in this topic thread until fine systems work well.
