The Caíco is a small boat used inside bays and rivers for service or fishing in the Lagoa dos Patos. It is found in several sizes from 2 to 8 meters, used with oars or with a simple sailing rig and a rudder. Usually built from Cedro or Grápia timber. Its design is flat with flat bottom and sides made with planks and carries a triangular sail, sometimes with a small jib.
