I love these videos! I also enjoy hull modeling and making crazy-wave RC boat videos, and learned that scale speed actually scales by the square root of length scale, rather than length scale itself. So for 1/200 scale, multiply the speed by about 14. Still really fast: 37 model mph scales to over 500 full scale mph - jumbo jet speed! Time also scales this way - if you want a "real" looking video, slow it to 1/14 speed. This is based on Froude number - it can be used to scale other hull parameters too.
