CUSTOM Aluminum Explorer
**Location update**
New Location opportunity - Owner Open to Discuss Delivery to Buyer’s Requested Destination
Now offered at a significantly reduced price, this yacht represents exceptional value for discerning buyers seeking maximum capability for their investment.
This striking 86-foot custom aluminium motor yacht embodies practicality, innovation, and a true spirit of adventure. Built by Primorets in 2010, she later underwent an extensive refit led by award-winning superyacht designer Greg Marshall, with the work completed in Vancouver, Canada.
The comprehensive rebuild revitalized the majority of onboard systems, enhanced both functionality and performance, and further strengthened her exploration credentials. Key upgrades include an extended swim platform that increased overall length and usability, along with expanded fuel capacity—making her even better suited for long-range cruising and remote destinations.
With her robust construction, thoughtful upgrades, and generous capacity for toys and equipment, this yacht is ideally suited as a family exploration vessel, offering comfort, reliability, and everything needed to fully enjoy the surrounding environment.
