Scale models for engineering studies can help evaluate seastead designs.
Basically if you scale dimensions down by 25 and speed down by 5 things will happen at the same relative fraction of hull speed. If wave heights and wave lengths are scaled by 25 then wave speeds are also down by 5. So things work out well. However, in the model everything is happening 5 times faster. So if you see something tip back and forth every 2 seconds in the model it would be every 10 seconds in the full sized version. A 10 knott wind in the model is like a 50 knott wind in full scale. The important relationship between 25 and 5 is that 5 is the square-root of 25. Works for other numbers with this important relationship too.
