Front fin(s) ?
On my long and narrow plywood paipo, when I turn, I feel like the pivot point is at the front of the board, the back of the board just reacts by "drifting".
This is when I ride on a very forward position.
It doesn't always turns this way (in a gently drifting move), sometimes it just side slips (so the pivot point is more the middle of the board) and then re-bite the face.
So I was wondering if some small fin(s) on the front on the board would help for these kind of drift turns.
I know it would probably won't work (otherwise it would exist already from a long time) but I always welcome the technical explanations.

Re: Front fin(s) ?
I think maybe better performance if you can figure out prone weight shift to engage the rail more. Not sure if easier or harder to do prone vs standing but here's a really nice standing version, I may have posted previously somewhere here

Fins in the front will cause the tail to slide out as soon as they engage. Board will follow path of least resistance,

Have you worked this out.
The solution is more in body weight distribution and keeping the rail engaged. This probably happens most in fat waves.

Re: Front fin(s) ?
I haven"t tried it, it was more a wonder than a project .
I have another "project" in mind which is to kneeboard my paipo, or even better, to "drop knee" it.
At my latest session there was a bodyboarder riding "drop knee", I though it looked fun but the classic bodyboard doesn't seem to provide planing enough, I'm sure a plywood board can do better.
The board is long enought I think but it is quite narrow so I m not sure it is possible, maybe I need to make another board, wider.
Another funny project is to add plywood to an existing pair of swimfins that I have. These are very confortable beginner bodyboard fins, relatively small (good for drop knee), but too soft to be really efficient. So I plan to pimp them up a little bit with a piece of thin plywood.

You are basically describing the drawbacks of having a long narrow board.

The bodyboard has been a very similar length to width ratio since it started in 1972. (if it was not right they would have made big changes by now)
I made a thin wood paipo the size of a bodyboard and is turns fast and tight just like a bodyboard
As your making boards from ply which is very cheap to experiment with I would suggest just trying normal bodyboard dimensions, 42" long 21" wide with some curve to the template. if you wanted to keep it longer try 45" by 19", I think a simple board like this will show you why the long board you have is surfing the way it is.
