Gooday, have a 7 metre aluminium with a Muir 500, reliable, strong, have 20 metres chain, spliced onto 12mm white rope, works well, tip,how it comes onto the boat via the bow roller, make sure it wont jump over the lip of the roller, had to reduce the size of our roller to stop this, it doesnt have a "free fall" but works pretty quick, another tip, they don't recommend you have it direct from the winch for an over night, make sure you put a tie off to reduce the load on the winch, cheers joe
