The 120’s are 10”(span or width) x 12” vs 12”(span)x12” on the standard tab. Just gives you some leeway in mounting ….. the 120’s have wings or fins that help channel the water out the back of the tab to generate the lift …making the 10” span efficient . I would think there would be some water release or “slip” from the sides of a standard flat tab hence a larger tab is needed.

I know I spoke with Tabman a long time ago and mentioned either tab would work but the 120 would give some more flexibility in mounting given the shape of the varying angles of deadrise in these boats ….

Have you ever been able to compare the 120’s to say the 12x12 tab …. Curious as to how the 120’s compare to a standard 12x12 tab … more , less or equal to... as far as in efficiency ….I wish I could find that picture of my hull we used to illustrate all this !!!!
