How to handle split trunk on young Maple

[Gpag]

I want to correct the issues with the Maple in the the photos before it gets any bigger. I think I need to remove the secondary trunk, cutting it at the top of the crotch but want to make sure. Is there anything else needed? The photos show the tree from different angles.
Thanks,

What kind of maple is it? If it's something that gets big, like Sugar Maple, you'd want to remove more lower branches as well. If it's something smaller, like a Japanese Maple, you don't really need to cut anything.

It will be a big one. Not sure what kind but certainly not a Japanese Maple. I’m sure it grew from a seed of one of the other surrounding maples.

Then you will probably want to remove all the branches on the main trunk up to the larger one just above the boat cover in picture 2. They are big cuts, but you're better off removing them now while it's still small as they'll only get bigger.
