Inrigger 4+ Four with

The Vikings had rowed across the sea for centuries. Inriggers are the modern advancement of these boats.
Unlike FISA Coastal boats, Inriggers are also well suited to cold waters, as Inriggers are designed to prevent waves from hitting the boat. FISA-Coastal boats, 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 get bathed in every wave. Maybe a nice thing in the Mediterranean at 25 degrees water and 35 degrees air, but not so great for the North Sea 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 breakwaters that prevent the waves from crashing in.Vikings have been rowing across the sea for centuries.
