After conducting research, I was unable to find any information about a boat ramp named Stan Blum Memorial Park in Florida with the provided latitude and longitude coordinates. It's possible that the information may be outdated or inaccurate.

However, in general, boat ramps in Florida are typically designed for various types of watercraft, including boats, kayaks, canoes, and jet skis. The width of a boat ramp can vary depending on its location and the volume of water traffic it receives, but most boat ramps in Florida are at least 20 feet wide.

The body of water that a boat ramp services can also vary, from rivers and lakes to bays and oceans. In Florida, there are numerous bodies of water that are popular for boating, including the Gulf of Mexico, Atlantic Ocean, Lake Okeechobee, and the St. Johns River.

In terms of permitted watercraft, Florida has regulations in place that require boats to be registered and follow certain safety measures. Certain watercraft, such as airboats, personal watercraft, and sailboards, may also have additional regulations or restrictions. It's important to check with local authorities or the Florida Fish and Wildlife Conservation Commission to determine what types of watercraft are permitted in a specific area.
