Certainly the very best of the popular Damen Sea Axe vessels with a Cat 437 commercially certified helicopter deck. UMBRA has been used worldwide for humanitarian aid and disaster relief missions for earthquake and typhoon victims as well as charitable scientific research. Yet, she has been properly maintained as a yacht and is ready to leave for her next mission on 24 hour notice. She would be a perfect fit for a large 150′ + superyacht circumnavigating! This type of vessel is becoming more and more popular, thanks to the amazing opportunity they offer. Look at the Damen Sea Axe in action with her mothership Vantage.
