Hi Captain Steve Worthington Thanks
From: captainsteve@manchesterliners.co.uk Yes Peter you are quite correct. It was called a Ralston and it was made Kelvin Hughes if my memory serves my right. Best regards, Steve Copy to Capt Cullen for interest - and maybe a few more comments. ____________________________________________________________________________________________ From: captainpete@manchesterliners.co.uk From: captainpete@manchesterliners.co.uk I first came across your enquiry via our hon sec which I acknowledged. Then I came across your e-mail to me. Yes you are correct the instrument you refer to was called The Ralston Indicator. This instrument was housed in a rectangular box with a hinged lid. When you lifted the lid inside was a metal profile of the vessel with the c of g of each cargo compartment marked. To operate you placed small metal blocks representing weights, ranging from 1000, 500, 200, 100, 50, 10, then a small range of small grey pcs for weights under 10 tons, in the various cargo compartments. For example if you had 2000 tons of Grain completely filling N0.2. 2 lower hold thenyou would place a black marked 2000 tons over the c o g of No 2 hold and so on until you had loaded the vessel. To get the Gm you then raised the profile of the vessel by two levers at the ends to get the Gm by balancing with use of the spirit level built in the the tray. To get the trim, you then lowered the tray back and again raised it by two levers at the sides, again balancing it with a second spirit level. The info you require ie the GM and Trim can be read off when you have balanced in each case. I used this instrument when I was mate on the Man Spinner, then Man City. Hope it all makes sense to you Peter. Regards Captain Pete Cullen
From: Peter Thompson Thank you for your detailed reply, I was on the "Miller" for
a while as 3/0 from 66 and remember the Mate Don Whitworth using this
machine...It was as you described and we used to use it under his instruction....I
do know it was on other vessels in the fleet. As I explained in my email
it was a query raised whilst on one of my watches at Nare Point (Cornwall)
coast watch,just one of my watch mates was a deck officer with clan line
and of the same era as we all are. So thank you both Capt Steve and Capt Pete for taking the time to reply Regards
From: Peter Thompson Hi Capt Steve W. Good to keep the old mind working,,,,,we
have a number of old salts at our station (Nare Point) from different
Companies but with plenty of memories....So to past the time during quiet
watch periods we get to have a good natter about the old days,,,,The
Coast watch station is one of the only ones we stand 2 personnel each
watch. The reason is that we cover a sea area from the Manacle Rocks
to the South across Falmouth bay to St Anthony head off Falmouth and
also up the Helford River... So thank you for your help in answering my question on the Ralston Indicator
so now I will put this enquiry to rest. Best wishes From: Peter Thompson Dear Capt Peter Cullen Regards
