Inrigger 4+ Four with

The Vikings have been rowing across the sea for centuries. Inriggers are the modern evolution of these boats.
In contrast to FISA coastal boats, inriggers are also well suited for cold waters, as inriggers are designed to prevent waves from hitting the boat. FISA-Coastal, on the other hand, have the philosophy that the waves hit the boat via the bow and run out again from the open stern. The catch is that the rowers sit in between and they are bathed by every wave. Perhaps a nice thing for 25 degree water and 35 degree air in the Mediterranean, but not so great for the North or Baltic Sea.
Inriggers, on the other hand, have an extremely wide bow with a lot of buoyancy, a closed bow and stern section with wave breakers that prevent the waves from crashing in.
