37-meter RMK Yacht "Seven Seas" In Build RMK Marine is presently building a 37-meter pocket explorer yacht for a client. It is expected to be called "Seven Seas" when completed. It showcases a design by Vripack who kindly released more information and photos on the new build. The owner wanted a big-ship feel and to pack many features that you perhaps would find on a vessel larger than 37-meters. As is typical for RMK builds, they are geared towards long-range cruising and exploring off the beaten track. Therefore her construction is being fashioned from steel.
