Di Maine, sebuah tim ayah-dan-putri memenangkan perlombaan perahu lobster.

“Dozens of boats zipped across Casco Bay during the Maine Lobster Boat Races on Saturday. Only one had a purple bottom. That boat, a 32-footer with a powerful diesel engine, belonged to Jeremy Beal, 45, a large, soft-spoken man who comes from a long line of boat builders and lobstermen.

For decades, Mr. Beal’s father, Wayne Beal, and an uncle, Calvin Beal, have built boats used by commercial fishers up and down the Maine coast. After years spent learning the family trade, Jeremy took over his dad’s business, Wayne Beal’s Boat Shop, in Jonesport, a seaside town more than 200 miles northeast of Portland.

To pay off the boat, Mr. Beal has returned part-time to lobster fishing, something he first started doing at age 6. This summer he has been helped by his 14-year-old daughter, Mariena Beal, who will enter ninth grade at Jonesport-Beals High School next month.

Together, father and daughter have been dropping 250 traps into the Gulf of Maine to catch thousands of the large lobsters prized around the world for their meat. They split whatever money is left after paying for the bait (herring, mostly), fuel, and the monthly boat bill.

Mr. Beal said he hoped the experience would teach his daughter both financial responsibility and the family’s way of life on the water. But Mariena didn’t quite get her way when it came to the color of the boat.

“She wanted a pink bottom, but I wouldn’t let that fly,” he said.

The pair hit on purple as a compromise. And Mariena got to name the boat — My Turn, she called it.

When they are not hauling up traps, Mr. Beal and his daughter have been competing on the lobster boat racing circuit, an annual series of summertime competitions along the Maine coast. The events, run by the Maine Lobster Boat Racing Association, are essentially drag races — the fastest boat wins.

“I’ve always been a competitor,” Mr. Beal said.

He summarized his racing strategy: “Point it and punch it!”

Race Prep

Two days before the recent race, Mr. Beal unloaded the buckets of herring he keeps on deck. He lugged out the lobster crates and the 55-gallon plastic drums that store the catch. Finally, he took a scrub brush and washed down the deck with Dawn dish soap.

On Friday morning, after waking early and packing sandwiches for lunch, Mr. Beal charted a scenic southwesterly course from Jonesport. Alone on deck, he took in the sight of the rocky coastline and marine life, including porpoises.

It took Mr. Beal just under five hours to sail to Long Island, one of Maine’s Casco Bay islands that lie a few miles from Portland. Many of its 230 residents work on boats or own one.

A crowd had gathered for a cookout at the old boathouse on Wharf Street when Mr. Beal moored his vessel. Men and women were eating hamburgers, drinking beer and lining up to buy race merchandise from Lisa Kimball, an islander who co-chairs the race. The proceeds were going toward a scholarship fund for children on the island.

Mr. Beal made the rounds. Several of the partygoers had bought their boats from him or his father. The price of lobsters was solid this year, everyone agreed, though the catch varied from “good” to “horrible,” depending on who you asked.

Adam Kimball, Ms. Kimball’s husband, planned to race the next day. He works on an oil tanker in Alaska, but you don’t need a commercial fishing license to compete — so long as you have a typical lobster boat, which he does.

“It’s a lot of money to spend for not a lot of return,” Mr. Kimball, 46, said with a laugh.

Dressed in a blue Hawaiian-print shirt, blue board shorts and Crocs, and nursing Canadian Club whiskey and ginger ale in a red plastic cup, Mr. Johnson, who is in his 70s, was trailed by a small entourage at the cookout.

It was getting late. Mr. Beal untied his boat and sailed over to Portland, where a friend was letting him dock while in town.

Mariena had missed the cookout — she was at the Maine Mall, the largest shopping plaza in the state, doing some back-to-school shopping with her mother. The next day, she would be at the wheel of My Turn.

And the Winner Is …

She also likes to shop. Mariena and her family members missed the noonish start time of the races on Saturday because they had gotten stuck in traffic after spending the morning back at the mall.

What did she plan to do with her winnings?

She smiled.

“Shop.””
