  Are yachts some kind of investment? Why would a man need ten yachts? Are they in various harbors in the world so he can go on a sea trip in any of his favorite locations? Or do yachts not degrade value-wise  and can be resold for roughly the same price (doesn't sound right)?
context: He owns at least 10 more yachts than was previously known, per the report.
  
  Imagine being so rich that investigations in to your assets can be off by ten yachts.
