Confused at Boat Ends? Symbols on the Bow and Stern

Confused at boat ends? Me too. Symbols on the bow and stern indicate a horizontal flow direction, inflow on one side, outflow on the other. But once flow gets out into a side flow path, it can go up or down, and/or it might do a horizontal side-loop and go back in, or a vertical upward flow and then do a loop-back to come down. So it's not one rule for every situation, unfortunately.

Image B has statue-of-liberty style of rays around a long-neck-bird on the right. But there is also a head inside the boat with rays too. I regard these as outflow going up to a Sol type of portal.

Near letter "B" is a symbol that reminded me of image A. What if it is serving as an opposite polarity portal of the bird head on the right? That would make it a Luna type symbol. These Luna kind of portals involve flow going up to higher density and coming down from higher density. Kind of like a conversation with God, so it's not wrong for image A to mean "diety", but I think the assyriology dictionaries "missed the boat" on the kind of portal this symbol can also represent. ( Did I wait for years to make this boat pun? Ya.)

The beast heads on the right of image C and D, they go across a barrier. C then shows some mouth outflow that does a loop-back. What "D" is doing at it's mouth flows is unclear.

The left side of "C" has the head "looking back", and that kind of pose is sort of like the scorpion tail, which is on image F and G. The blue squiggle on the left beast's nose is probably a portal symbol. https://ca.pinterest.com/stevenbhalls/squiggle/

Image E has a swan neck doing a loop-back. I used to think long-neck-birds were "just outflow", but the loop-back aspect seems to indicate some are bidirectional, ( and there is a Luna in the top-right corner). Surrealist artists seem to know things.

Image H has a slight clue, a bull head "looking back" on the right, which could indicate the bidirectional side, but I'm not sure yet.

Image J has a simple outflow barrier penetration on the right. The left side has a fishtail inflow shape, but that group of little people's legs touching it is quite odd. A crowd means higher density and straight legs are downward flow.

Image I has a right side with an upflow cone and a long-neck-bird on top, but doing a loop-back with it's neck, so it's still confusing.

Do I have a point? Normies see a boat carved on a rock and say things like, it's "Noah's ark", or there was a "great flood". But it could have been carved only to show symbolism. More boats: https://ca.pinterest.com/stevenbhalls/boat-ship/
