Jim Clark — Athena · #18 · Est. $95 million

Athena, associated with Jim Clark, receives a reported $95 million estimate in the ranking. The sailing yacht stands out for marrying imposing scale with a traditional wind-powered silhouette, especially through its prominent masts and broad deck plan. Its custom rigging, complex construction, and uncommon size help explain why the article places such a high value on a vessel built around performance as well as presence.

Clark is a Silicon Valley entrepreneur best known for co-founding Netscape and helping shape the commercial internet era. The source describes Athena as his commission, connecting his appetite for advanced engineering with an older sailing tradition; that remains an association rather than a claim of current ownership. The contrast is apt: a technology pioneer choosing a technically demanding yacht whose drama comes from sails, proportion, and craftsmanship.
