I know that it is not depicted on the map, but I found a different solution. If we assume that there is a triangle with four trees on the first edge, two trees on the second edge and no tree on the third edge, then it goes as follows;
The pirate tied up on the vertex of the triangle where the first and second edge meets, sees 2 trees only (one tree hiding the other three trees on the first edge and one tree hiding the second tree on the second edge.
The pirate that sees 3 trees is tied up on the other vertex of the triangle where the first and third edge meet, seeing the opposite side of the triangle with the two trees and one tree of his side, hiding the other three trees.
The pirate that sees 5 trees is tied up on the other vertex of the triangle where the second and third edge meet, seeing the opposite side of the triangle with all the four trees and the tree of his side, hiding the other one tree.
The pirate that sees 6 trees is tied up on the second edge of the triangle between the two trees, seeing the opposite side of the triangle with all the four trees and both trees of his edge, since he is between them.
Finally, the pirate that sees 4 trees is tied up on the first edge of the triangle between the four trees, seeing the two trees of the second opposite edge and seeing only two trees of his edge (since he is found between two trees out of four on a line, can only see his adjacent trees on this line, hiding the remaining trees.

Yes, Daniel, ANY 2 and 4-tree Vee will work, no matter what the size of the island is, because there will be one and only one spot from which only two trees can be seen, there will be two and only two spots from which only three trees can be seen, and there will be three and only three spots from which only four trees can be seen. How many spots there are from which only five trees can be seen depends on how far apart the trees are from each other in each of the two lines, and then how large the island is relative to those distances. In any event, it's a finite number.
What is not true, however, is that ANY 3 and 3-tree Vee will work. As you can discern just from assessing the frame at 3: 11 -- there's no spot where one possibly could stand and see only three trees. And even when irregular spacing does combine with sufficient room to make such a thing possible -- such as what you model at frame 3: 31 -- this amounts to a complete one-off type situation, and not just one where you can say that as long as there's a point of convergence. Many and in fact most 3 and 3-tree Vees would not work, while there are no occasions where a 2 and 4-tree Vee would NOT work, so long as the point of convergence is on land.

The riddle was not well conveyed to the audience.
The riddle consists of finding an arrangement of points of view and viewed objects that allows a number of viewers to see a certain number of objects. However, you should also include in description the fact that trees block the view of the trees that are behind them in a straight line.
The fact that trees block the view of the trees behind them, is absolutely non applicable to our world. Therefore, since it is something specific to the riddle it should be shared with the audience while describing the riddle.
How could we know that the pirates cannot move their heads? Tilting your head allows you to circumvent that blocked view problem.
Putting the fact that trees block the view of other trees in the solution as an assumption, is wrong, and transforms the riddle from points of view vs viewed objects into assuming that trees block the views of the trees behind them, which no one will assume. It should be included in the description.
It's a pity. it would otherwise be a very interesting material.

This riddle is poorly constructed. Almost all puzzles and riddles are designed to only have one valid solution, where as this puzzle has a wide range of valid solutions, and it is only after the fact that they reveal that this is ok and that they werent looking for a specific solution. There is a reason for this convention amongst riddle designers, so people dont wast time and get frustrated by trying to do something that isnt possible given the available information.
If they werent looking for a specific answer, they should have made that clear in the beginning, instead of retconning new information in at the end to make it possible to solve down to one. The bit about oh by the way, would you look at that, there is only one such island, what a happy coincidence is a cludge to to try to salvage a malformed riddle, It is cheating. the riddle made me waste my time by looking for an answer that they asked for, but didn't actually want in the end.
Also a lot of other people thought they were tied to the trees apperently, so its badly phrased as well.

Yeah, but the islands must have different shapes and sizes, and there must be a lot of islands. And we don't even get some kind of multiple choice question. And there are a lot more ways to line the trees to get the same result. So, this isn't even a question, it's more of a make-some-information-up situation.

Cool
OK I have to say you werent exactly clear on this riddle
When you said the Pirates were bound I thought they were all bound to a specific tree
They could look in any and all directions from the tree but were bound to a tree
So you threw me off by not being specific

If the two lines of three trees where pointing at an angle like a triangle and u were sitting at the point where they converge, u will be able to see the trees in behind. This is illogical.
