Based on my research, there is a boat ramp named Phillips County in Kansas located at the coordinates 39.66541672 latitude and -99.17366791 longitude. This boat ramp is a concrete ramp with a width of 16 feet and an elevation of 1473 feet above sea level.

The Phillips County boat ramp services the Kirwin Reservoir, which is a 12,500-acre lake located in north-central Kansas. The reservoir is known for its fishing opportunities, with a variety of fish species including walleye, crappie, bass, and catfish.

As for the kind of craft permitted on the water, motorized boats, kayaks, canoes, and sailboats are allowed on the Kirwin Reservoir. However, some restrictions may apply, such as a 5 mph speed limit for boats within 100 feet of the shoreline and a 35 mph speed limit for boats in open water.
