Hi Ron
I apologise in advance to any 'Booth Boys' if the info that follows is incorrect.
There were four v/l’s, to become the 'V boats'. When built 1961 they were,1300grt (ish).
A couple of years later they were lengthened by 60 feet to accommodate Gemini cranes, thus taking the grt to 1609.
I had assumed that the R/O's cabin and R/Room had been part of the original build?
It may have been a cock up, but in reality, with the experience that Lamport Holt and Booth Line may have gained with R/T only may have led to the decision to carry an R/O.
We did carry 6 passengers.
They were not heavy TFC ships, and when on the river we did not keep H8 watchkeeping, just listening for TFC lists, ship skeds and the British Consul, Pat Nicols up at Iquitos.
However comms when required could be difficult on the river, and from Brazil to UK, USA and West Indies.
On a visit to Governors Island (AMVER), the watchkeeper to demonstrate the SURPIC procedure asked us to give a position, which we did, which was Manaus. It was not on their SURPIC coverage, we joked, but that is another story
