I'm going to build a simple pier at the summer cottage. Not a swimming pier but one you can walk out on to fish.
(We have a plot with 50 meters of shoreline. It's quite shallow which makes it difficult to fish from land. We have a swimming pier, albeit just a few meters out into the water. But two boys who can't agree on where to stand and cast in the evening...)
In one spot it's extra shallow (20 cm) about 4-5 meters out before it becomes at least 70-80 cm deep. They dredged for the boat a long time ago.
I'm thinking the simplest way is to take 2 pcs of 45*170 at 4.8m and join them together on cc 60, then lay full lengths of decking 28*120 at 4.8m along the length. You never see others laying decking that way. Is there a reason to cut? It doesn't need to be more than 6 boards wide, I think. Taken up in the fall. Placed on stones or similar, can have support in the middle and a little flex doesn't matter much here.
Or does anyone have a completely different suggestion?

I think the simplest approach will be to take 2 pieces of 45*170 at 4.8m and brace them together at cc 60, then run full lengths of decking 28*120 at 4.8m along the length. You never see others run the decking in that direction. Is there any reason to stand and cut? It doesn’t need to be more than 6 planks wide I think. Taken up in the fall. Placed on stones or similar, can have support in the middle and a little flexibility doesn't matter much here.

Sounds like a simple solution. If you lay the boards crosswise, you avoid bracing; otherwise, there's no reason. Consider how heavy it will be if it needs to be taken in for the fall.
Hey there! Just wanted to add that one of the main reasons is that they become more slippery lengthwise than crosswise over time. Since you move along the length and the moving mass that needs to be stopped is also going lengthwise, if the boards run lengthwise and are slippery, it becomes like skating with your feet. I also believe the reason you see them running across as you mentioned is that the supporting joists are often lengthwise, which in turn often rest on cross beams attached to, for example, a concrete pillar. Layer upon layer upon layer so it becomes cross, length, cross in direction. So, you rarely put nogging in between but instead underneath at the bearing points, and this way the dock is raised higher, which also makes it less slippery and less exposed to water wear.
The difference is that it requires more studs when you need something to screw into.
So crosswise it will be cheaper + less weight.
And you can let the cross board extend a bit further over the edge, so you get a wider dock for free.
If you are going to pull it up, it is probably easier to place it on float blocks/barrels.
Then a steel pipe at the far end to tie it to in the summer.
The reason for the common construction is the simplicity with two beams, making it easy to attach masses of transverse planks in any desired width. With 60cm between the beams, you can easily achieve a width of, for example, 80cm. With an electric saw set to 80cm, you just feed it and cut.
Calculate the price of the different options! Planks, studs, and screws.
Otherwise, you have a pretty good summary: Weight, width, slipperiness, comparing against each other.
It is somewhat easier to cut planks than to cut studs.
Decking SHOULD be laid lengthwise as it stiffens the structure in the direction that is otherwise the most difficult to manage. That is, it's more correct to lay it lengthwise. Go for it.
I think you put too much faith in a couple of boys' ability to get along just because they have access to their own docks for fishing. I envision arguments arising when decisions have to be made about who gets to stand on which dock, followed by arguments when one wants to switch for no apparent reason, and naturally, one will want to switch docks when the other catches something from his dock.
Otherwise, I agree that crosswise decking is best, the nicest, and the easiest.
edit: Some experience in the subject of quarreling boys has been acquired through growing up with a brother two years older, as well as attempts to keep in order two bonus boys. A thousand docks wouldn't help.
