It's the Capitana C-27 w/ Captain Jonah Martinez and the crew hard at it working Disney.
Those guys have been working their butts off this year, I wish them much success.
I had hopes...but I got skunked
That "jet ski" is a little center console skiff used for setting anchors.
About working in the winter...sometime in late October or November the wind will begin to blow. If we are lucky, sometimes there is a period around the first part of January when the wind lays down enough for a week or three to give us long period wave heights under 3 ft and visibility over 3 feet, but not always. I've just been observing for a decade or so, and if you don't see something like " winds 5-10 knots and seas 1-2 ft with a period of (at least) 8 seconds" on the marine forecast, no one that likes their equipment is going to be backing up to the beach.
