It looks like the website has not been updated since 2022 and indeed you need to register. If you go under 'Manage Account' you may be able to register. I tried to register but I got an error saying 'Login failed! Account is not active'.  I got an email saying "Your account must be approved before being activated. Once your account has been approved, you will be notified." So I am waiting for the account to be approved...

I'll keep you posted

Seeing the pictures that @lmccaskill uploaded got my brain storming, so to say. Are you working with similar small boats? I was assuming bigger fishing ships that are registered somewhere. If the boats are not registered and there are no existing photos of them, and you want to identify the individual boats, you'll need to build your own catalogue to train an AI.

However / in addition, if the boats have written text on them with a name or a code or number, like in the pictures, then it should be ridiculously easy to identify boats. No AI needed. I discovered recently that my laptop has started showing find results based on text in photos. If different boats are of the same model, again like in the pictures, then there is nothing else left than what is written on them ... well, perhaps the color scheme.

... or perhaps face recognition if the image quality allows it. But then you'll be at square 1 again with training an AI.

We have recently applied funding for one of these to find bird nests on the tundra in Greenland.

Yes,  if the canopy is sparse enough, you can see through the canopy with TIR what you cannot see in the RGB. We had tested with large mammals like rhinos and elephants that we could not see at all with the RGB under a semi-sparse canopy but were very clearly visible in TIR. It was actually quite surprising how easily we could detect the mammals under the canopy. It's likely similar for mid-sized mammals that live in the canopy that those drier seasons will be much easier to detect, although we did not test small mammals for visibility through the seasons. Other research has and there are a number of studies on primates now. 

I did quite a bit of flying above the canopy, and did not have many problems. It's just a matter of always flying bit higher than the canopy. There are built in crash avoidance mechanisms in the drones themselves for safety so they do not crash, although they do get confused with a very brancy understory. They often miss smaller branches.If you look in the specifications of the particular UAV you will see they do not perform well with certain understories, so there is a chance of crashing. The same with telephone wires or other infrastructure that you have to be careful about. 

Also, it's good practice to always be able to see the drone, line-of-sight, which is actually a requirement for flight operations in many countries. Although you may be able to get around it by being in a tower or being in an open area. 

 Some studies have used AI classifiers and interesting frameworks to discuss full or partial detections, sometimes it is unknown if it is the animal of interest. I would carefully plan any fieldwork around the seasons and make sure to get any of your paperwork approved well before the months of the dry season. It's going to be your best chance to detect them.
