We could sail quite well on beam reach on the starboard tack, but sometimes had to push a little with our “iron Genua” (=nanny engine) against the side tide. The 50NM distance took us 8 hours, from 8-16, a normal working day.
It may be that the name Dieppe origins from the Norse language. It is a deep harbour (djup in Swedish) and the tide has a difference of 6 meters, whereas special constructions for the berth is required. It is easy to feel a little bit dizzy when you walk down.
