The given map details Porth Harbor in the past and alterations made in the present day. Looking from an overall perspective, it is readily apparent that the harbor has become more accessible through additional docking options, and transitioned generally from being used for commercial fishing and some private boating to a mostly recreational waterfront area.
In the past, there was a single dock in the norther section of the harbor, just below a public beach stretching further northwards. At present, the beach remains the same but another dock serving passenger ferries has been added. Slightly south and west of the docks, there was previously a marina for private yachts, showers and toilets and a car park connected to the main road running north to south. The only change today is the marina has now been relocated to the immediate south
In the southwestern section of the harbor, the marina (which replaced an open harbor for fishing boats) is adjacent to new showers and toilets and a pre-existing second car park linked to the main road. On the eastern peninsula, the existing lifeboat and private beach are now accompanied by cafes and shops and a smaller road leading to a new hotel to the furthest eastern point.
