TANDEM SAIL ADAPTOR KIT - For boat serial numbers 1544 through 5751 (tandem kayaks newer than serial number 5751 do not require an adapter). This part is installed in the seat scupper of the forward seat to allow you to use Hobie's Kayak Sail kit on the Tandem. Only the aft seating position can be used when a sail is installed on the Tandem Mirage.
Serial numbers are located near the stern of the boat on the bottom side. For Mirage Tandems, the serial number is the first four digits after the "CCMY".
