"Kinds" there seems to refer to divisions of life-forms wherein each division allows for cross-fertility within its limits. So one kind vs another kind could be determined where fertilization ceases to occur.
Creationists, at least the ones that try to think, abandoned that criterion decades ago.
It inexorably links to the conclusion that Noye would have needed a fleet of arques to accommodate two or seven of each kind.
A huge fleet. One that would put the US Navy to shame.
