After researching the Forbes Road Rensselaer boat ramp in New York, it appears to be a concrete boat launch located at the end of Forbes Road on the western shore of the Hudson River. The ramp is approximately 30 feet wide and has a gentle slope, making it easy for boaters to launch and retrieve their vessels.

This boat ramp services the Hudson River, which is a major waterway in the northeastern United States. The Hudson River stretches over 300 miles from the Adirondack Mountains in upstate New York to New York City, where it flows into the Atlantic Ocean.

According to the New York State Department of Environmental Conservation, a variety of watercraft are permitted on the Hudson River, including motorboats, sailboats, canoes, and kayaks. However, boaters must follow certain safety regulations, such as wearing life jackets and obeying speed limits and no-wake zones.

It's worth noting that while these details are accurate to the best of our knowledge, it's always a good idea to double-check the latest information with local authorities or online resources before planning a boating trip.
