But Revhead, surely the makers of the funny fish you love so much can't be wrong?
I agree, hydrofoils have been around for 50+ years and the vertical support element has always been called a strut. Before that, struts were the vertical supports that hold the propeller shaft under the hull.
I have to admit though, I have called it a mast regularly now because I've heard/read it so often. I'd say it's 50/50 usage now, but I think that's fine. Everyone usually knows what you're talking about.

Are you saying this shows that mast is the right word or not? I think this passage proves that it is not how mast has been used in the past. All of this is about supporting something up in the air. A vertical support for something under the water (propeller shaft, hydrofoil) is a strut.
I'm cool with strut or mast though
