Most of my fishing is catch and release, so I don't really worry about them "getting away." But if you want to keep trout, just be more aggressive about pulling them out of the water. If you are going to keep the fish anyway, be direct and as they get close to hand, pull them well up onto the shore.

As for a net...the mesh bags for groceries would also work...but I don't like the idea of a coathanger. Rust, poking holes in pakcs, etc.
