HERE IS AN ITEM THAT I BOUGHT AT A LOCAL SPORTING GOODS AUCTION. I AM NOT SURE HOW IT IS SUPPOSED TO WORK. THE BRAND NAME IS LAUNCH AIDE. IT IS NOT MADE FOR TOWING & HAS A LOAD LIMIT OF 250 POUNDS. IT IS SUPPOSED TO BE USED ONLY FOR LAUNCHING & RETRIEVING OF WATERCRAFT. THE PREVIOUS OWNER WAS A DUCK & GOOSE HUNTER & I ASSUME HE USED IT TO LAUNCH HIS WATERFOWL BOAT WHEN HE WENT HUNTING
