    I’ve read with interest the concerns about building seasteads that are tough enough to withstand 15 to 30 M waves. It appeared that this was considered to be normal in blue water. I am concerned that “we” may be designing to too high a standard, so I was hoping to get some diffinative answers about what the norm is for wave size. There will of course have to be consideration for rogue waves, but if we can determine if these are limitted to certain areas, this could make seasteading much less expensive. I did a quick search for wave heights and this is what I found. http://www.oceanweather.com/data/

    Now maybe I picked a VERY calm day or season, but I see a lot of blue water that’s 0 to 7 feet. Any other inputs / data?

    Thank you for your help; you are totally right that finding a good location with managable waves is key to making seasteading affordable. We are looking for an oceanographer to help us answer these questions; if you know any that might be interested, please send them our way!

    The picture you show here is a snapshot in time though; maximum significant height wil vary over time. The relevant factor is the maximum height you are likely to encounter over extended periods of time. This may of cource be much higher than the waves at any given time.

    Besides, as a matter of probability, about one wave in every 1000 will be two times the significant height; and some higher than that still.

    Wave heights at one particular time is interesting, but not as useful as data for many years, averages, peaks, distributions, etc.

    It’s pretty though. :)

    I would feel safer living on a seastead knowing it was constructed for maximum effective safety (especially if I would be trying to make a life there).
