....which brings us back to the rope! (or a trailer with a longer drawbar)
Another thing to think about - a bunk trailer, although arguably better for the hull on the road, will need to go a lot further into the water than a swing beam roller type to get the boat off. My current boat came with a bunk trailer. Had to unchitch & rope it every time to get it off & on. Traded it in for a swing beam roller. Only once had to unhitch since (see above!) and I now don't even get the back tyres wet most times.
