I rigged the W500 to row or sail and can add my 30 pound trolling motor if the wind continues to quit too far away for an easy row back. A pair of smaller sealed batteries are perfect for twin hulls, and sitting a couple of inches forward balance it all.
A cross bar gives the oarlocks a four-foot spread and removes with two hand knobs, so the boat passes through the back door. It goes in my Honda with the front seat folded and rolls on a pair of 9” tires from (something) tucked between the hulls on PVC pipe held up by bungee cords.
A box like your motor mount is the base for a 45 square foot Snark lateen sail I had, and drops down about as far as the big foam noodles underneath. Those even match the ones around the coaming, which are smaller, so I can get my big feet between them and the seat!
