The safety chain is all kinds of goofy and is already on my list of things to fix this winter, but I think the length is actually correct. The trailer has a detachable tongue and the chains are mounted just behind the detachment point. My understanding is that safety chains can't be mounted to any detachable part of the trailer frame, but I need to research more. But, right now it only has one chain (the attachment point on the left is AWOL) and the chain is MUCH too light for the boat. My utility trailer has much heavier duty chains. The attachment point on the right also looks very weak. Oh, and it doesn't have a heavy duty clip, but rather the seller had been using a small bolt through the chain with a small nut on it to loop it back to itself. I think I've been hitting around 4400 max but I don't like to spend much time up there since I haven't gotten fully comfortable with the reliability of this one yet. I'm a 1.82 ratio on the OD. From what I've seen with this boat, most people seem to suggest 17 for acceleration and 19 for speed, and not really much out of that range. I fully support getting the Donzi out there!
