Police said two Asian businessmen were travelling by boat from Ngella to Guadalcanal on Sunday when they were attacked by three men.
The robbers made off with almost $US40,000 in cash.
The police have warned people not to transport large amounts of money without proper security.
They're appealing to seafarers to come forward if they have information about the incident.
