/diy/ - Do It Yourself

looking to /diy/ a cover for a small fishing boat (16ft long) and I've settled on building a frame that sits on top of the boat that will be covered with a tarp
the issue is I would need the water to run off and not pool on the tarp so a frame to support and give a raised center
what would be the best way to attach boards to the center spar?
preferably so they can be disassembled and reassembled
I was thinking just a couple lag bolts for the fore/aft as those are the simplest, but do I go find some sort of bracket or is there an easy way to join some 2x4's at an arbitrary angle?
I have access to a miter saw
