A lawsuit against Larry Ellison ’s sailing squad, which has led to the seizure of one of his million-dollar boats, is also revealing how much the Oracle Corp. founder is willing to spend to win the America’s Cup: $300,000 a year for a rank-and-file sailor.

The litigation is the latest in a series of legal battles that have surrounded the billionaire’s sailing successes.

On Monday morning, two federal marshals walked into the San Francisco waterfront base of the sailing squad, Oracle Team USA, and seized three gray, whale-size containers holding the disassembled parts of a 45-foot-long, seven-story-tall yacht called an AC45, according to the plaintiff’s lawyer and a U.S. Marshals spokesman.

The marshals tagged the three containers, which can’t be moved until a judge issues a ruling on the seizure or allows the team to post a bond on the boat. The vessel, a smaller version of Oracle’s victorious 72-foot-long boat in the 2013 America’s Cup, is being held as a lien, or collateral, in the case. The plaintiff asked for the seizure.

The plaintiff is Joe Spooner, who spent a decade as an Oracle sailor until the team dismissed him in January. A 41-year-old New Zealand native, Spooner in February sued the team for $725,000 in wages over a 2½-year span, as well as double-wage penalties, punitive damages and legal fees, alleging the squad wrongfully discharged him without cause.

A team Oracle spokesman declined to comment, citing pending litigation. A spokeswoman for Ellison, who is Oracle Corp.’s executive chairman, also declined to comment.

Court filings show that Spooner signed a contract with the Oracle team that would have paid him $25,000 a month, which equates to $300,000 a year, from July 2014 to the end of the next America’s Cup, the world’s most prestigious yacht race, which is scheduled to be held in Bermuda in 2017.

In Spooner’s termination letter, team Oracle general manager Grant Simmer said Spooner asked for raise to $38,000 a month to relocate from San Francisco to Bermuda. Simmer said in the letter that the team wasn’t prepared to modify the squad’s relocation policy specifically for Spooner, and that the team also declined to increase his pay.

“For these reasons, and in the light of the stated position that you will not otherwise relocate to Bermuda, this letter constitutes prior written notice of termination” of Spooner’s contract, Simmer wrote.

Spooner was one of six grinders on the 11-man Oracle team that won the 2013 America’s Cup. In sailing, grinders are the equivalent of football offensive linemen, cranking hand-powered winches to power a boat’s hydraulics system. They are typically the lowest-paid members of a sailing team; the people who adjust the sails and helm the wheel can get paid double, or even more.

Oracle is the world’s top sailing squad, having won the past two America’s Cup contests, and Ellison has spent lavishly to retain the world’s best yachtsmen. The managing director of Emirates Team New Zealand, the runner-up in the 2013 Cup, has estimated that his sailors got paid half as much as Oracle’s, an appraisal that other sailing experts this week said sounded accurate.

Ellison spent at least $115 million overall on his team’s 2013 America’s Cup campaign, the Oracle team’s chief executive has said.

During Ellison’s recent Cup victories, his lawyers have taken the field almost as often as his sailors. He first captured the 2010 Cup after a 2½-year legal battle over the competition’s rules. Among other accusations, the Swiss team Alinghi alleged it caught a man who was hired by Ellison’s crew to spy on Alinghi operations. An Oracle spokesman said at the time that those were trumped-up allegations that had nothing to do with the legal matter at hand.

Another team Oracle grinder, Matt Mitchell, has sued the team for $68,000 in legal fees that he said he accumulated while fighting allegations that he helped alter an Oracle racing boat in preliminary competition before the 2013 Cup. An Oracle team spokesman declined to comment.

An international jury had concluded that Oracle was guilty of making illegal modifications to the boat and forced the team to start the first-to-nine-wins 2013 Cup races with negative-two victories. On the brink of defeat, Oracle ended up winning the final eight races of the 2013 contest to stage one of the most dramatic comebacks in sports history.
