Chart from this “brilliant windsurf sail size calculator”:http://www.vims.edu/general/sailpaddle/SailCalculator.xls, found over at “the rec.windsurfing group”:http://groups.google.com/group/rec.windsurfing/browse_thread/thread/6baff8bc311ce24b/10a3de4885fae60e?hl=en#10a3de4885fae60e.

The data for the above chart. “Buoyweather.com has the current wind speeds and wave condition’s of the Karachi Coast”:http://www.buoyweather.com/wxnav6.jsp?region=pakistan&program=Maps. The wind speeds and sea conditions are pretty accurate for Karachi even though the free data is only available a bit far off shore.
It is a different matter that the local waters around Karachi are so polluted that it’s not safe to come into skin contact, let alone ingest it.
