Salesforce CEO Marc Benioff loves all things Hawaii.He wears Hawaiian shirts to work and even named his dog "Koa," a word that means"daring warrior" in the native tongue.He also owns a 5-acre estate on the Big Island, which he purchased for $12.5 million in 2000 and constructed over several years.He said at a 2012 conferencethat he spends about a third of his total time at his vacation home.And one of the things he likes to do while he's there is ride a Gibbs Quadski XL, an all-terrain vehicle that can instantly transform into a watercraft. The Quadski XL is quite the billionaire toy 'itcan travel up to 45 miles per hour on both water and land and theytypically costabout $50,000 each.Benioff recently gave two Quadskis to the San Francisco Police and Fire Departments as a gift, apparently because he thought they would be helpful for water rescues.When deciding whether they would accept the gift, the Board of Supervisors valued the amphibious vehicles at$50,550 each.After a bit of deliberation, the board ended up accepting the gift for use by emergency personnel. The SFPD even took one of the Quadskis out for a spin last weekend.Great to see @Sfpd @SFPDChiefSuhr making good use of the @GibbsSportsAmp Quadski. I am sure Batkid would like a ride! pic.twitter.com/gOiDxrn3H2' Marc Benioff (@Benioff) July 27, 2015Check out this video to see the Quadski in action.SEE ALSO:The most over-the-top tech billionaire vacation homesJoin the conversation about this storyNOW WATCH: The 13 best beaches in America
