Thought I'd drop these for photoanalysis. Wish Boatfags were here to see them.

No scale available that I could find. Last 2 are max rez from the site. With no scale, I'm estimating size based on the comparison of chairs around the pool and the width of the nearby "road" and walkway into the pool area on Pedo Island, that pool being located not far from Vessels 3 & 4 (and yes, I used the same max rez setting.) Did not include a shot of the pool/road.
Vessel No. 1 is tied to the seaward side of the covered dock. It looks like a twin-outboard RHIB, approx 9 meters/28 feet in length. Notice the hard-top. It looks similar in design to the closed cockpit Zodiac RHIBs used by the Coasties.
Vessel No. 2 looks like a small inter-island ferry-type vessel. Notice the hard top runs nearly the full length of the boat from forward of the cockpit to almost all the way to the engines. Estimated length is 10 meters/30 feet, give or take one or 2. Also notice that the bow opens out very wide in a short space, and the boat does not narrow slightly at the stern. Looks like it was made for max sitting space (indicative of a ferry).
Vessels No. 3a and 3b look like a sailboat and RHIB tender. The sailboat narrows significantly and rounds out aft, motor vessels tend to be wider with straight sterns. The tender looks like one of those 8-footers that sailboats like to tow around.
Vessel No. 4 (yes, I know it has a tender nested at the stern) looks like a catamaran- or trimaran-type vessell. Has obvious twin hulls, uncertain whether it has a middle hull. Estimated length is 19 meters/60 feet. The tender looks like another RHIB yacht tender, judging from the cat's size it looks like a 4 meter/12 footer. Pretty common size for yacht tenders.
Thought this might be interesting. I haven't seen these before (I'm a part-timer so I very well could have missed them). Was particularly interested to see a cat at the island, they are nowhere near as common as single-hulls and one of this size might make it easier to narrow the search down.
Note that the website is either owned by or scraped from Goog and it copyrighted the imagery with a 2019 copyright. Not buying that just yet, I think these images may be older. I didn't do a comparison of the buildings to verify, somebody familiar with Pedo Island's current construction should do that.
And no, I can't tell the maker of these vessels from looking at them. I used to be in the Nav and never paid much attention to civvie boats. We just considered them nuisances or targets.
Hope this helps someone.
