The original question in this thread was trying to right the Nacra 6.0 solo. The power righter is not for single-handing a Nacra 6.0.
It does work, it does work well.
And yes the mount on the beam does not have to be directly behind the dolphin striker -- it can be off to either side.
Hope this reviews some misconceptions.
They are a good product, they work well, and work fine for every boat I have used them on.
