That's what I was planning on doing, I am just not very familiar with JS, and was hoping someone could help with that

Also, do you think boats are a little too weak? In my mod, I had increased resistance and health on arrow ships and siege ships, and lowered damage on the ram ship. What do you think?

Yes, I had been thinking about doing other boat changes, and it looks like you already did them

But that's caps with teeth, just caps I think would be safe to place in the Archaic period, maybe even from before, down to the Iliad, which has no mention of such things (EDIT: obviously just a log would appear somewhere around here first, so it would be fine to start in 776 BC with a log and soon after either capping it, for more attack, or having a shed for it, for more resistance). Regarding the boulders mentioned in the Iliad, I can only guess, but apparently (can't remember myself since I've read it 25 years ago) they were used by the Trojans against the Greek fortifications (if such a thing even existed), and not the other way around. This could be both because the Greek fortifications (and gate) would have been much weaker, and because the terrain played against them (the plain coming mostly downwards from Troy to the shore, and the Greeks having not much of a choice than to build on low ground). And although there are no reliable sources regarding superhumans lifting impossibly heavy boulders, there are cases of boulders being rolled down for defensive purposes, from Xenophon's Anabasis ("when the rearguard, so advancing, had reached a ravine which they must cross in order to strike up the steep, at that instant the barbarians began rolling down great boulders, each a wagon load, some larger, some smaller; against the rocks they crashed and splintered flying like slingstones in every direction") to New Zealand, according to https://teara.govt.nz/en/rock-limestone-and-clay/print ("the defenders would hurl stones and roll boulders onto the enemy").

I've seen some sources describe it as 450 BC, which would be some 30 years after the end of archaic period. So might be close  enough to assume something similar already existed in late archaic period. But probably better to just have the log ram and other early methods.
