Kayak Upgrade: Independent Quattro Sponsons

Upgrade your double Klepper or Longhaul kayak to have an additional sponson effectively upgrading it to the latest Quattro configuration. I bought these to upgrade my kayak for a Lake Malawi circumnavigation that never happened. Item still in package, never opened. From supplier "Independent Quattro Sponsons attach to the bottom stringer of the gunwales, are independent of the hull, and allow paddlers to easily upgrade their boats. The set of two sponsons simply attach to the frame before assembly is completed and the skin is set in place, then inflated."
