The shipowner said it placed debt of NOK 50m ($7.4m) in an open issue that could rise to NOK 500m.
The bonds mature on 1 May 2020 and carry interest of Nibor plus 6.75%.
The cash will be used for general corporate purposes.
SpareBank 1 Markets acted as arranger of the new bond issue.
It follows a NOK 500m sale last December.
Trondheim-based Boa had at the time already repurchased NOK 140.3m
