Good Day,

I am making a model of a Humpback whale and I am having trouble figuring out approximately how thick a Humpback whales pectoral fins are?

I have all the dimensions for the body size fairly well scaled in relation to other parts on the Humpback whale model, however I can not figure out if I support the pectoral "flippers" to the extent I want to, would it be too thick and out of proportion.

I still have to wrap everything in paper mache and a few other layers and I don't want to make it absurdly thick pectoral fins by adding two more layers of foam board.

I've tried searching some relevant terms and I just can not get the dimensions.

I have length and width fairly proportional to the body and tale, thickness of the pectoral fins is a big mystery to me.

So in an adult male or female Humpback whale, how thick are the pectoral fins?

Thank you.
