I had on my last boat I sold and Loved it !!!! main reason was launching alone and when my wife would fish with me ,she does not know how to back a trailer so I would get it close so all she had to do was back me in the water a little I would pull launch lever the boat would slide off into the water !!! best thing was putting the boat back on the trailer I would back it in , get out and drive the boat on the trailer until I heard it CLICK tell the wife pull all the way up
to the loading area !!! Best moneys I ever spent !!! and I will have on my next Boat too for sure !!!!!
