Ive seen the video and stills of the voyage across the lagoon inlet. As to whether the average person can do it, I woud think something like that is just as much mental as physical, possibly moreso.
Im a very seasoned backpacker. Very little worries me. Im not afraid of bugs, snakes and other critters, heights, caves, etc. Ive camped in the rain, in the cold, in the hottest summers, mountains. Ive hiked along trails that a foot wide with tright down drop offs. I generally have a "bring it on" attitude when it comes to being out doors. But many people I know thing a Motel 6 is "roughing it" and youd be hard pressed to convince the average person to go crawling into a wild cave or go camping in bear country. They might be physically able but they cant get past the mental squick factor.
Then again, there are people who live in the water. They love boating, tubing, swimming. They are a bunch of fish. I may be a Chuck Norris on land But I am a bloody coward when it comes to water. I dont like being on boats or in water where I cant see the bottom. Though I can swim, I rarely do and its usually to get back on dry land after someone pushed me. Ive seen the video and gotten the heebie-jeebies but reading Ricks description of the water depth (For whatever reason I had it in my head that the water was knee deep) just makes my skin crawl. Im going to go with a great big "NOPE" to wading across.. COULD I do it? Physically I think I could. Mentally, I dont think you could PAY me enough! Knowing my luck, the sharks would decide I would make a tasty side dish. Rick, you are exceedingly braver than I am!
On a side note, lobsters on Niku?
