At many sites with water access, people want to be able to launch boats. These may range from small kayaks and canoes that can be easily carried from a car roof rack to the water, to larger sailing or motorboats, which need ramps into the water to launch them. In remoter locations it might be appropriate to allow only those craft that can be manhandled, while in the busier areas nearer cities boat launch areas, mooring jetties or even fully fledged marina facilities with refuelling places might be provided. This is partly to reduce the degree of development, the number of artefacts and the use of motorboats in wilder places. The use of materials

(d) The layout of the road to and from the ramp allows the towing vehicle to turn to reverse down it and then to park, after launching the boat, in a pull-through parking area nearby.

should also reflect the environment. However, good, simple, well-constructed facilities are needed for durability, appearance and safety. When planning for boat use, the launching ramp or jetty should be chosen for the landscape setting as well as the type of boats, site requirements and safety.
