How is the best way to measure halibut? I see lots of posts of halibut caught that are right at 133cm. Some of these are guides and it seems like they would want to make sure they are not bonking over size fish. I caught one that I though was close this year and messed around a bit trying to measure it in the water. I felt pretty confident it was under but was still paranoid so netted the damn thing and put it on the floor of the boat and then measured again before I gave it the wood shampoo. It ended up being just a hair under 133 cm. After that I have decided if it is remotely close I am just cutting the leader and letting it go. I don't want to bonk a halibut and then have it be 134 cm. By the way netting a 74# halibut is a little interesting and not something I would do again or recommend.
