Bingo! Spot on answer, DAZZLER Tom. Here's what my brother-in-law said about the loading procedure to take the panga out to see the penguins on the nearby islands:
"So way down in Chiloe Island on the beach we drove on, we started to check out the penguin trip. It was rainy and cold so we decided not to do that but we watched the boat getting loaded here's a picture they essentially load you in a grocery cart especially with the specially high clearance to keep you above the water and then of course bigger wheels and throw you out and put you on board towards the front and push the boat out a little farther than that take another 10 to 12 people and put them on The boat. It's a hoot! As you can see everybody got their bright yellow rain slicker on...!
That's a jumbo sized panga! Thanks to Tom and Marilee for the photos.
