SEATTLE — Sig Hansen admits this: He doesn't read a lot of books.

And the idea of doing one himself sounded like more trouble than this “Deadliest Catch” skipper could tolerate, even though people around him had been suggesting it for years.

But once a publicist connected Hansen, who lives in Shoreline, Wash., just north of Seattle, with Montana-based outdoor writer Mark Sundeen, things fell into place.

“Basically, all I had to do is open my mouth and talk,” said Hansen. “How hard is that?”

Apparently, not too hard. Their collaboration, “North by Northwestern: A Seafaring Family on Deadly Alaskan Waters” is to be released this week by St. Martin's Press (304 pp., $25.99).

Viewers of “Deadliest Catch,” starting its sixth season April 13 on the Discovery Channel, know that Hansen is seldom at a loss for words, whether he's complaining about the Bering Sea weather, sparring with fellow skippers or urging his crew members to pull another line of crab pots even though they've been at it 30 straight hours.

“This is what we do,” says Hansen, 43. “It's either this or flip burgers.”

Given Hansen's hard-driving style, it's conceivable he would have made a rather formidable burger-flipper, if life had pointed him that direction.

But would he have fans in 150 countries — and have made guest appearances with Jay Leno, Conan O'Brien, Jimmy Kimmel, Jim “Mad Money” Cramer and each of the Stewarts — Martha and Jon? Would his work have inspired a product line that includes coffee mugs, mouse pads, fish sticks, a Rogue ale and an X-box video game?

Likely not.

In the pages of “North by Northwestern,” readers will learn of the heritage that led Hansen and his younger brothers, Norman and Edgar, to a life on Alaskan waters. When his grade-school classmates were learning their ABCs, Sigurd Johnny Hansen was drawing fishing boats with swirls of black coming out of their smokestacks.

Though the media may portray today's “Deadliest Catch” fishermen as tough, Hansen insists, “You ain't seen nothing. You should have seen my dad ... my granddad, my Uncle Karl, and all the men who came over from Norway or ventured north from Seattle to pioneer the crab industry long before cable television, GPS, satellite phones and computer depth finders and plotters. Hell, they were doing it in wooden boats.”

Like many of his countrymen, Sverre (Svare-ee) Hansen, Sig's father, settled in Ballard, epicenter of Seattle's Scandinavian heritage. That's where Sig was born in 1966.

And even though the family moved to Shoreline while Sig was still an infant, the bonds of the Norwegian community were so strong that his mother, Snefryd, seldom needed more English than it took to navigate the grocery store.

In first grade, Sig was sent home with a note reading, “Teach him English. Stop speaking Norwegian.”

Even today, Hansen speaks Norwegian at home with his wife, June, and his stepdaughters, Nina, 18, and Mandy, 14, and walks in Ballard's annual Norwegian Constitution Day Parade in May.

And at least once a year, the family makes a visit to Norway, and in particular, to the island of Karmoy, which produced not only the Hansens' parents, but the women Sig and Edgar Hansen married. Norman Hansen is single.

Each of the three Hansen brothers owns an equal stake in the Northwestern, but as maritime tradition dictates, Captain Sig is boss on board. That doesn't stop Edgar, 39, the cutup in the family, from complaining to the Discovery Channel cameras about “Psycho Sig.” Norman Hansen, 42, the shy brother, usually stays out of view.

The Hansens knock on wood each time they say that the Northwestern, the 1977-vintage, Seattle-built fishing boat they inherited from their father, has had no fatalities, permanent injuries or major mishaps.

Sverre Hansen wasn't as fortunate with his earlier boat, the wooden Foremost, which burned and sank in the Bering Sea in 1969, leaving Hansen and his three-man crew bobbing in stormy waters for hours until another fishing boat came to their aid. Each chapter of “North by Northwestern” opens with an installment in the story of the Foremost's harrowing end.

Sverre Hansen died of a heart attack in 2001, years before “Deadliest Catch” turned his sons into folk heroes.

What Sverre Hansen might have thought of the showbiz side of the Northwestern isn't clear to Sig, who himself is amazed the series has lasted this long.

“When we did it that first time, we figured OK, we'll do this as a nice tribute to our industry, to our family, and that will be it. But from there it just kept going.”
