In February 2008 Hamilton joined the board of directors of H2O Audio, a watersports music company in San Diego California. He had used H2O Audio products on many of his long distance paddling endeavors before joining the company. Later in 2008 he published a book which he describes as not an autobiography, but discussing his philosophy of life. On August 27, 2014, Hamilton was in the news again for riding waves and boards which few others dared. Hurricane Marie caused Southern California to be hit with a swell of extreme size—triple over head (and larger) waves could be found from San Diego to Los Angeles, including Laird's home break at Malibu. Late in the day, on a stand-up paddle board, Hamilton dropped into one of the largest waves of the day and proceeded to "shoot" the Malibu beach pier at an extremely high speed. Despite being one of the best known surfers since the time of Duke Kahanamoku, the matured Hamilton avoids self-promotion. He serves as an ambassador of surfing and watersports and occasional lifeguard to other tow-in surfers. Hamilton is also an environmental activist. He joined a protest in Malibu against a proposed plant, which would affect the quality of the local waters. Other celebrities attended the event, including Pierce Brosnan, Halle Berry and Ted Danson. In April 2018, Laird made worldwide news for voluntarily rescuing people around Kauai, Hawaii from devastating, record-breaking storms that were causing flooding. Laird, who lives on the island and used his own boat, has assisted many families in evacuating the island from the flooding, and is being hailed a hero. Laird Hamilton is a co-founder and co-creator of XPT Life or Extreme Performance Training, along with his wife, Gabrielle Reece. Laird Hamilton, along with Paul Hodge and Gabrielle Reece, co-founded Laird Superfood in 2015. In September 2020 the company went public on the NYSE under the id LSF. Personal life Hamilton has a daughter with his first wife, big-wave surfer and clothing designer Maria Souza. Hamilton and second wife Gabrielle Reece have two daughters together. Hamilton and his family split their time between residences in Kauai, Hawaii, and Malibu, California. Hamilton and Reece have been described as part of the "Malibu Mob", a celebrity group in the same vein as the Brat Pack. Other Malibu Mob members include Chris Chelios, John Cusack, Kelsey Grammer, John C. McGinley, Tony Danza, Justin Long, Ed O'Neill,
