Got the bait cutting board almost ready.
Didn’t want to spend too much on a manufactured one. True to my style I ended up spending about the same (sometimes more) on a custom one rather than buying ready to bolt on.
This one is very portable but eats up a rod holder location, is13 x 20, costs about $80

This one Franco posted a while back. I robbed most of the ideas from it. It’s 15 ½ x13, costs about $37.

This is what I ended up with, up to this point.

It is 15 x 20 removable, very storable probably got about $40 in it.
Still got to add the sides and knife holder.
