As we leveled off at 11;000 FT [ATC asked us to verify] that we were leveling at 11;000. This made us check why he would ask and we realized that I had misread the descent profile. The Center Controller had cleared us to 'descend via' the Chins Arrival landing south and I saw the note at RADDY Intersection showing that aircraft landing at Boeing Field cross at 250 KTS and 11;000 FT.What I had missed was that it showed that this was for Runway 31. All I concentrated on was the ''Landing Boeing Field' note. Since we were landing south; we should have crossed RADDY at 16;000; but this restriction is in the same note as another Landing North note and in a separate box from the Boeing Field box. I would like to see an addition to the Boeing Field box that clarifies that Boeing Field aircraft also need to cross RADDY at 16;000 FT. I should have also briefed the descent better with the Co-pilot; but I thought it was simply the RADDY at 11;000 FT crossing.There was not a conflict with any other traffic.
Confused by the graphic and textual format of the CHINS STAR to SEA (although planning to land at BFI; an 'airport also served' by the arrival) the Captain of a G200 crossed RADDY at 11;000 as charted for arrivals landing BFI on Runway 31. Unfortunately; Runway 13 was his runway of intended landing which requires crossing RADDY at 16;000 FT and at an IAS 20 KTS faster than designated for a Runway 31 landing.
