Don’t avoid buying the boat you want because you are stressed about launching it. It’s a minor inconvenience vs. all the other stress these things cause in our life!! $$$$
This is my favourite solo launching setup - I have copied this guy’s technique and setup exactly, and I find it to be excellent.
I am no trailering stud here, and only have to do this a couple times a year with a ~31 foot overall Grady. I don’t even own a truck! Just rent…
I love how the process is so calm - no running around, shouting at buddies or even revving up the engines to get the boat off and on.
