What Beachwalker said.....
I browsed the DEM regs this morning, and couldn't find any info about gaffs.....I looked in the text regs page under both "Striped Bass" and "Equipment Regulations", and found no mention of gaffs......
But that doesn't necessarily mean it's legal..........
Here's the link if someone wants to look further.....
