Boyer used a rope system on their A cats and Taipans for quite some time. Sailed some of these boats too. The 4.9 also has the rope system. My personal experience is shared by many who also got rid of any ropes nowadays. The fear for jamming the rope between the board and the case is not worth the benefit of the system. In theory it sounds nice to go on a flyer and just pull the rope for the leeward daggerboard to lift it, but than again, you can do the same a few meters further down the track without any of these ropes too. I think nowadays very few A still use a rope system. Just didn't pay off. And once you really jammed a board you surely want to get rid of all those lines. Just imagine approaching the beach and you don't get your board up. Ends up expensive.

I nowadays glue some webbing to the case in the upper and lower part to increase enough friction the board stays up when lifted (and stays there in a capsize) and thats it. No lines, no extra weight and a clean tramp!
