A jetty is a structure at the waters edge, starting above high water mark. Extending into the water, often beyond the low water mark, it is designed to give access from the land to ships moored alongside it. A jetty may be a solid structure, like a very thick wall, but is often an open framework.
A groin (groyne in the UK) is situated in a similar place. It is always a solid structure, and is intended to give shelter to ships (or more often small boats) alongside it. It is not intended to give access to the boats. A groin is often called a breakwater. Groins are also used to reduce shoreline erosion along susceptible coastal areas.
