In designing seasteads we need to understand what amount of motion is acceptable.
The basic problem is that your brain is used to being able to tell what vertical is by looking at buildings and things, but on a ship it is not so simple. The conflict between visual cues, your inner ear, and the motion your body feels causes the trouble.
There have been studies working out formulas for what amount of motion causes sea sickness.
In general it seems that after a few hours to a few days people develop "sea legs" and are adapted. If tourists are coming for 1 week visits a few days to adapt takes away a lot of the fun. If a family is moving onto a seastead for good, a few days to adapt is no big deal. So for short term tourism reducing motion is much more important.
Many people travel on small boats with lots of motion and are fine after an adjustment period.
