There seems to be an error in the question, as Rangeley is actually located in Maine, not New Hampshire.

That being said, the boat ramp named Park Road Rangeley is located on Rangeley Lake in Maine (latitude: 44.96457672, longitude: -70.64576721). It is a concrete boat ramp and is approximately 20 feet wide.

Rangeley Lake is a large freshwater lake that covers 6,327 acres and has a maximum depth of 149 feet. The lake is known for its excellent fishing, including trout, salmon, and bass.

A variety of watercraft are permitted on Rangeley Lake, including motorboats, canoes, kayaks, and paddleboards. However, it is important to note that all boats must abide by Maine state laws and regulations, including proper registration, required safety equipment, and adherence to speed limits and no-wake zones.
