Ever since the northern shores of Central Bellisseria are placed, residents can sail (or ride a speedboat) to/from the Welcome Hub. Unfortunately, there is no place where the ship/boat can berth.
I propose setting down a proper pier/port where ships & boats can berth -- for a limited amount of time -- so that mentors that own ships/boats can take new residents out for some sailing.
It will be a great introduction for new residents on what kind of activities they can do in Second Life.
