Sennet, hand twisted from natural fibers, was the original cordage used to lash the 'iako to the ama and the main hull. While many lashing styles were used, the primary purpose was to ensure the canoe's safety. If lashings broke, they would not unravel because of the cord's interlacing and cinching.
Rigging is what keeps the main hull, the 'iako, and the ama together. An important part of paddling is to learn the culture. This includes learning traditional Polynesian lashing techniques. The MANU’IWA OUTRIGGER Force Fives and Duke are each primarily lashed using these methods. Secondary, or temporary, lashing can be made with modern snap-lashes. However, each paddler is expected to not only learn but to assist in rigging the boats. A video is available for team member use.
