The first entry in the Certificate of British Registry lists Jesse Frank Collier, Master Builder from Worthing, Sussex as the owner in March, 1936. The Certificate also refers to an auxiliary petrol internal combustion engine, 1934, Stuart Turner, 2 cylinder, 6hp. We assume this to be her first auxiliary engine.
From 1900 until 1905, Lloyds Register of Yachts lists two owners for ‘Cachalot’: RC Boothby of Sydenham, London and WA Fraser, also of London. ‘Cachalot’ did not have an engine at this time and was registered at Shoreham, London. From 1934 she was registered in Ipswich.
