- The founder and commander of the highly successful team of joint service, multi-racial and multi-national teams of Coastwatchers who served in the critical days of the Pacific War was Commander Eric A Feldt, RAN. He was an ‘Australian Argonaut’ – see Q 6
- AMSA MO 504 requires that the master of a domestic commercial vessel must know number of passengers on board at any time. The new regulation provides some detail on how this can be achieved .
- A whale ‘graveyard’ under water is a whale fall. The first found in Australian waters was in Bremer Canyon, less than 100km off WA’s southern coast. It was found by scientists from UWA and the Western Australian Museum.
- To ‘marry’ a rope is to bring two ropes adjacent so they can be hauled simultaneously.
- The ‘metracentric height’ is the vertical distance between a vessel’s metacentre and her centre of gravity. The metacentre must be above the centre of gravity. It is critical to the righting moment of a vessel when she rolls. Recent container vessel events have been worsened by containers on the upper deck that raise the centre of gravity so high the reduced metacentric height lessens their ability to recover from a roll in heavy seas.
- The first class of cadets at the Royal Australian Naval College in 1915 was nicknamed the Argonauts. Their story of tragedy and success is told superbly by Peter Jones in his book ‘ Australia’s Argonauts … ‘
- Belgian Abraham Ortelius (1527-98) was famous for compiling a comprehensive world atlas. Firstly in1570 and then in 25 further editions in several European languages. He was encouraged by Gerardus Mercator who introduced his new projection the year before Ortelius published his atlas.
- The first non-manual power used in an America’s Cup racing yacht was in 2010 when both yachts used a small engine to help sail their multihulls. In 2013 & 2017, hydraulic power was provided by ‘grinder’ crew members, to store hydraulic pressure which was bled off as sails and foils were trimmed. In 2021, extra power will come from rechargeable batteries providing power to control and trim the foils. The grinders will again generate stored hydraulic power to trim the sails, but may only use their arms to do.
- Main advantage of the stern wheel fitted vessels in the early days of steam was they could operate in inland waters with shoals or even rapids. They were mostly replaced with paddle (side) wheelers but continue in some parts.
- The 2020 Rolex Sydney-Hobart Yacht race will feature Two- handed yachts for the first time, ahead of their inclusion in Paris 2024 Olympic Games. There are stringent conditions for these competitors that include having completed a minimum qualifying race or 24-hour passage two-handed, completion of a Sailing Safety and Sea Survival Course, and have Senior First Aid and Long Range Marine Radio Operators Certificates. The 2020 Race will mark 75 years of female participation.

- The first ‘commercially successful’ container ship sailed in 1956 – SS Ideal X, a converted WW2 oil tanker. Various containers had been tried for centuries but standardised containers removed the need for manual sorting of shipments, most warehousing, and most dock workers. They reduced port congestion, shipping times and losses from damage and theft.
- Coastal freighter SS Wollongbar lost off Crescent Head NSW on 29 April 1943, and just discovered, was sunk by a Japanese submarine with the loss of 23 of its 28 crew members.
- The largest submarine ever built is the Russian Typhoon (or Shark) class. It carried ballistic missiles and was 175m long with a submerged displacement of over 48 000 tonnes. It had twin pressure hulls and extensive facilities for crew welfare.
- Independent Regatta Director for the 2021 America’s Cup is Australian Iain Murray – his third such role. He has contested numerous world championships for 18ft skiffs and Etchells, four America’s Cups, and 26 Sydney-Hobart yacht races with three overall victories. John Craig was the previous AC IRD, and David Graham is CEO of World Sailing.
- To ‘dubb ‘in relation to a wooden vessel is to smooth a plank with an adze to make it suitable for use on the deck or sides. An adze was also used to assess the condition of ageing planks.
- Fishing outside countries’ Exclusive Economic Zones is governed by Regional Fisheries Management Organisations (RFMO) and their member countries. Most RFMO manage fish stocks in their region, but some manage highly migratory fish species like tuna and dolphins.
- Major restoration projects under way by Sydney Heritage Fleet number Two. These are 1927 Steam Ship John Oxley and 1950s Speedboat Kookaburra II. Several small wooden boats are also being restored.
- A ‘mast coat’ is intended to prevent entry of water where the mast penetrates the main deck and is stepped above the keel. It is usually made of painted canvas or rubber.
- RAN’s Plan Galileo is intended to change how Navy carries out sustainment of the Fleet. It involves integrated Capability Life Cycle management, learning new technologies, and generating the necessary skilled workforce.
- U Boat Worx Nemo 2-seat personal submersible costs EUR€975,000 (approx. AUD$1,620,000) and weighs 2,500kgs.
