People and background
Mark and Marijke Ham.
Joost Ham
They have their teenage (Els, Annelies and Thomas) children on board who have their own channel called Sailing Surya.
This family are originally from Denmark and have explored much of the Netherlands, Norway and the Mediterranean Sea.
Their friend Ann is also seen on some episodes.
They also have their dog dogs onboard. Morris is their Wolf Pomeranian and Nelson which is a Chihuahua.
Boats and projects
The boats below are part of the channel’s earlier story; ownership and equipment may have changed since those episodes.
Boat details
Greatcircle has a 2021 Outremer 55. They have opted for as much carbon fiber as much as possible.
This is only hull #4 of the current model. The 55 is one of Outremer’s latest models and became popular after Sailing La Vagabonde became a brand ambassador.
Previously they had a Lagoon 52S catamaran called S/V Greatcircle and carried the name forward onto the new channel, although the Outremer is called S/V Surya.
Previous to this, they owned a Lagoon 39 catamaran.
And previous to that, they had a smaller Rival 34 yacht which Marijke originally owned when she was younger, so this was actually bought back but then later sold to make room for the Lagoon.
Refits and equipment
They have upgraded their Outremer catamaran extensively, but I’m not entirely sure which options they chose. I’ll reach out and update this article soon.

Is there a verified net-worth figure?
No verified financial disclosure is cited in this profile. The earlier estimate has been removed because a boat’s value, video views and assumed income do not establish someone’s net worth.
