Here is a photo of my solution.
The two carabiners clip to the front of my BCD during the dive, enabling me to have my hands free if necessary. The length of the ropes are carefully measured so, with my arms at their farthest stretch, the ropes are taut, adding a little to the overall camera stability.
On the surface, I unclip the carabiners from my BCD and clip them together. This then becomes a harness for someone on the boat to grasp and lift the unit out of the water. I can lift the joined carabiners a long way out of the water so the person does not need to lean down so far. Given the attachment point is at the top of the handles and most of the weight is in the housing and battery packs, the unit hangs vertically when lifted.
The yellow nylon platted rope loops back into itself and is joined by melting in the middle. The arms of the housing would rip off before this rope broke.
Works for me.

Peter
