The Use of the Lead and Line by Early Navigators in the North Sea?

Kemp J. F.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2014

Vol. 8 no. 4

481--483

This paper draws attention to the lack of information as to how early North Sea sailors navigated, particularly during the one thousand year period that followed Roman times. The lead and line was the only navigational aid available for most of this period, but there is little recorded as to whether it was used simply for ensuring a ship or boat had enough water to proceed or whether, together with the knowledge it provided of the nature of the sea bed, it was used as a more positive position fixing device. The author would appreciate any information relating to navigation techniques used during this period.

The Colregs and the Princess Alice

Kemp J. F.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2007

Vol. 1, no. 1

57--61

There is currently considerable interest in the international regulations for preventing collisions at sea (the Colregs). Suggestions for changes are made, but their validity is difficult to assess because, apart from some very limited simulator experiments, there is no possibility of testing new proposals before they are introduced. Given this situation, it is instructive to look back at past times when the Colregs were somewhat different so that we may, at least, avoid some of the mistakes of the past. In this paper, the author’s aim is to look at the lessons that might be learned from one, particularly tragic collision between the Princess Alice and the Bywell Castle in 1878.
