Swordboat captain and bestselling author Linda Greenlaw will introduce her newest book, “Seaworthy: A Swordboat Captain Returns to the Sea” with a talk Sunday, July 18 at 3 p.m. Jointly sponsored by the Penobscot Marine Museum and Left Bank Books, the talk will take place at the First Congregational Church, 8 Church St., just adjacent to the downtown museum campus.

The event is free and the entire community is invited; there will be “seaworthy” snacks and a party afterward.

Greenlaw, who lives on Isle au Haut and is still the only female swordboat captain in the world, came to fame a dozen years ago as the real-life heroine of the book and movie “The Perfect Storm.” In 1999, she told her own version of that story in “The Hungry Ocean,” which rose to No. 5 on the New York Times bestseller list, followed by “The Lobster Chronicles,” which rose to No. 2. In the years since, she has written a third bestseller, “All Fishermen are Liars”; two mysteries; and a cookbook co-authored with her mother, all the while setting lobster traps full-time.

Now, 10 years after her decision to retire from swordfishing, Greenlaw returns to the ocean with “Seaworthy: A Swordboat Captain Returns to the Sea,” a fish tale, thriller and unexpected adventure about her middle-age craving for one challenge more. It all started innocently enough, Greenlaw writes: “The truck was on its last gasp. My lobster traps were not producing enough to pay expenses. There was a pile of unpaid bills on the kitchen table.” What better time to say “yes” to a chance to captain a ship?

It turned out not to be the return to glory Greenlaw imagined, but it provided her great material for a return to writing. The book is laced with Greenlaw’s trademark honesty, intelligence and Downeast humor. These days, Greenlaw also stars in a Discovery Channel series called “Swords.” Its second season will start next month.
