If you stay at the Paradis Malihide in Rwanda you’ll get to watch these fishermen leaving at about 6pm each day in these huge rowboats to fish lake Kivu for sambassa and tilapia. They stay out all night, returning at about 7am the next day. The canoes are made of three hulls, attached by beams. The paddling happens in the two outriggers and it takes the a long time to get up to speed.
On our first day there we heard them singing on their way out and ran, in the rain to the docks to watch. Looking out at this departure is incredible as at least a dozen of these giant canoes slowly make their way to deeper water. The spindly bits sticking out each end of the canoes are for stretching their nets out.
