When fishing for salmon, I routinely use frozen "cut-plug" herring of anchovies for bait. Cut plugging is removing the head from the rest of the body with a 45 degree cut and 45 degree bevel.

This causes the bait to do a floppy roll through the water adding flash and a wounded bait fish appearance.

In the past, I used the surface of my front hatch for an improvised cutting board. It worked, but it did a lot of cosmetic damage. So once again, I came up with an invention only I will probably ever need and it really isn't necessary for me either. But hey, I have to justify all the money I spent on my CNC router. Also, making stuff is fun! Here is the drawing done in Fusion 360:


Like the rod holder mount I did earlier, I made a template with the pen holder so I can minimize HDPE waste. For this particular project, I wanted it easily removable and I did not want to drill any holes. I am no naval architect, but from my limited knowledge, the less holes in a boat the better. Therefore, I got 8 neodymium magnets - 4 for the cutting board and 4 for inside the hatch. I cut out and pocketed the cutting board and pressed in the magnets.
The following short video shows the build, and how it attaches to the hatch.
