This sounds incredibly legit, but question: Could you not gain a shit ton of momentum sailing directly with the wind in a regular boat, then drop your sails and steer into the direction of it to maintain some amount of velocity for an amount of time? Feels like the same principle could be applied here, especially because they would swap between photon momentum and gravitational momentum

You can do that with a sail boat because the keel prevents lateral movement. In space if you try to turn without trust then you just spin and keep heading into the original direction. You can definitely leverage gravity wells for additional thrust in a spaceship, but that's a whole other conversation. My idea was to try to tack into the light source with a solar sail, like you would tack into the wind with a sailboat, but use a propellant based keel to offset the lateral movement in the direction the photons are heading. But I suspect that it would be more efficient to just use the propellant as your thrust in the direction you want to go. Idk if using it as a keel is even possible. I feel like someone way smarter than me would have proposed it already if it was possible.

Yeah, in space there's nothing to push against so all turning the sail would do would be presenting a smaller surface to be pushed directly away from the sun
