British marinas might be shamefully expensive, but at least the finger pontoons are generally long enough for the yacht. This is often not so elsewhere.
And it must be said that there are plenty of shorties cropping up in home waters. The problem this causes, if you have come in bow to, for example, is how to stop the stern blowing away untidily. The answer is to accept that the line from the extreme quarter to the finger is no more than a stern spring line stopping the boat from moving backwards and to secure her athwartships position by rigging bow lines port and starboard to the walkway. The cantilever effect does the rest. All you have to remember then is not to fall into the drink when you jump down onto a finger whose buoyancy is less than your body weight!
