It was a light-air day
on upper Galveston Bay; winds were in the 8-10kt range.

8 to 10 knot winds are "normal" most of the time for most of the sailing world
outside the trade wind areas. Light airs are winds under 6 knots.

a Tayana 37
would do 125-mile days.

few boats consistently average 125 mile days over the long haul.
