During this time he was instrumental in establishing the TS. Esperance to train naval sea cadets. Bern arranged the charter of the well known racing schooner Astor, for one pound per year, to be used as a sea cadet training vessel. Up to 80 sea cadets received training on Astor for the year. Seven were selected to sail as crew-members in the 1964 Sydney to Hobart yacht race in which the vessel won line honours. There were 18 in the crew including Peter Warner the owner as Skipper, and Bern as Sailing Master.
In 1965 Astor was sold to a wealthy American and Bern accepted the offer of delivery skipper to Los Angeles. Sailing from Hobart in March 1965, Astor was delivered to her new owners in May 1965.
Bern travelled to England where he bought an ex-Fisheries Research and Protection vessel, MFV Kathleen del Mar. With his family and two sea cadets aboard the vessel they sailed for home in September via the Panama Canal arriving in Hobart in May 1966.
After this vessel was sold, Bern converted the 110' ferry Sorrento to an abalone mother ship, returning on one trip of five days with 25 tons. The biggest quantity of abalone ever caught in the world.
Bern was instrumental in having abalone delivered to port alive and in the shell, rather than being shucked at sea in less than ideal conditions. He was the driving force behind the introduction of the limiting of abalone licences to 125 for Tasmania, which still stands.
Next, in 1972, came the building of Australia's first purpose built abalone mother ship, the 160 tons Tasmanian Enterprise which could carry alive, 20 tons. In 1977 Bern and his wife Jan sailed the well known 73' schooner Derwent Hunter back to Tasmania from Cairns, Q. The vessel needed a new bottom and full restoration and this was completed in 1978.
By 1983 Bern had sold out of the fishing industry but in 1984 he bought a 50' prawn trawler to sample prawn fishing in semi tropical waters.
In 1986 he sailed with four crew around Tasmania in a 28' 6" whaleboat, emulating Captain James Kelly's voyage of 1815-16.
In 1987 with a volunteer crew Bern re-enacted the return voyage of George Bass from Westernport to Sydney, in the whaleboat. 1988 with a replacement stainless steel knee, he sold the prawn trawler Episode and retired. In late 1988 Bern gathered together a group of students and seamen to fully rig the brig Lady Nelson. He became her first captain. He received a second replacement stainless steel knee in 1990.
In 1997 Bern and crew re-enacted the whaleboat voyage of George Bass from Sydney to Westernport, exactly 200 years later to the day. They then continued on through the Rip across Port Phillip and up the Yarra River to Melbourne. The first whaleboat to do so.
After taking three years to organise the building of the replica Norfolk, Bern and crew re-enacted the 1798-99 circumnavigation of Tasmania by Bass and Flinders, exactly 200 years later.
In July 1999, again with volunteer crew he re-enacted the voyage of Matthew Flinders from Sydney to Yamba and on to Moreton Bay, Hervey Bay and return to Sydney.
The original Norfolk had been used as a trading vessel on the Hawkesbury River, and this was re-enacted by a journey of 200 miles from Sydney to Windsor and return to Sydney in October, 1999. Bern and Norfolk arrived back in Hobart in early November 99 having sailed over 6500 miles without an engine. In 1999 he received the Australian Senior Achievers Award in Canberra.
Bern was appointed an Officer in the Order of Australia on Australia Day 2000 for services to the community and to the fishing industry, for the training of sea cadets and for services to Australia's maritime history.
