She is recognized as being one of the first registered female sea captains or ship masters in North America.

At age 21, Kool joined the Merchant Marine School in Saint John, New Brunswick, being the only woman to ever do so.

Her father turned the title to the scow over to her and she captained it for five years, working mainly the pulp and paper trade in the Bay of Fundy.

In 1944, after her ship caught fire,[5] Kool left life at sea to marry Ray Blaisdell of Bucksport, Maine in 1944.

As of 2011[update], the home she grew up in is being rebuilt from the original remains and an exhibit is planned at the entrance of Fundy National Park.
