I am in the middle of removing mine right now on a Melges 24. I am using an Oscillating Saw with a flat blade. It allows me to take up big chunks at a time and then I go back and hand scrape with a 4" razor blade. Remove residual glue of MEK and then sand smooth.
This my third time in 7 years to replace the hydroturf. the first 2 times i did it by hand with a putty knife and a 2" razor blade. That sucked.
I've also done it multiple times and have used these same techniques.
