Been doing some blue crabbing in Mass. this year. They seem way faster than Lobster. Plus seem way more aggressive. Has anyone dove or snorkled for these critters? If so did you catch them by hand?

California Dungeness by hand.
Maryland Blue by chicken wire net. Can be caught by hand, but they swim fast compared to heavier crabs without back fins.
I think if freediving off your boat or kayak then also bait some traps to attract crabs.
