Yup. Same yard, same crane, probably same guys. They did good.
The key bit is that you/they want the sling positioned so that it is slightly above the mast's center of gravity. Too high and it'll be butt-heavy, which is suboptimal but not a huge problem. Too low and it'll be tip-heavy, which will be really hard to control when going into the boat.
With our tapered rigs, a good spot will be near the mid-point of the spar. Because the butt-end is full profile, even being *exactly* at the midpoint will still mean the sling is slightly above the mast's CG.
