Hi Keith (Bill),
Having read your post I took the liberty of checking the ships on which you served and am inclined to think that both the 'Baltic Trader' and the 'Baltic
Exporter' (both U.B.C.) would have had the push button system or a similar system requiring a regular watch on the helm (or rudder) indicator as well as the compass or course indicator. The 'Verdaguer' (one of mine - I missed you by two months) as one of MacAndrew's ships, was probably from the same
German shipyards as the U.B.C. boats, where, in those days, there seemed to be a tendency to use all manner of helm controls other than the conventional wheel. As much as I've tried I cannot remember what system was adopted on the 'Verdaguer'. Having sailed in a number of 'Baltic Boats' and 'Mac Boats' I came across various types of helm controls. Apart from the push-button system, there was another that consisted of a small half-wheel about the size of a small car steering wheel( but shaped like that of an aircraft pilot's), which was operated by steering right (S) or left (P) 1-5 notches depending on the degree of rudder required. One other was simply a small vertical pole (about 2 feet high) that was pushed to P or S , again with 1-5 notches as mentioned above. All required a watchful eye on the rudder indicator. I didn't mind them once I got used to them, but they didn't have the 'feel' one got from a conventional wheel. I raise the matter, Keith, not in any way doubting your word, but it would have been interesting to find out what system these three ships were fitted with and besides that old mate, it was all fifty years ago and memory dims

One of our members, Alec (Trader), was also on the 'Baltic Trader' at one time, so hopefully he may read this and be able to help us.
