Abstract
It will be impossible to replace all the ferry routes with regular roads. However, looking at the social economic benefits, one will soon discover that it will pay to shorten the ferry routes as much as possible. One way of shortening the ferry links is to challenge the forces of the nature and actually place the ferry harbour out towards the open sea. The Mortavika Harbour has been placed at the outermost point of Rennesoy, andis part of the Rennesoy- Mainland Connection (RENFAST). The paper describes the hydraulic investigations programme which was required to ensure an acceptable level of service and safety and even structural integrity of the ferry terminal. The paper also includes a description of the berm-breakwater which was constructed and experiences from the construction period.
