Bonjour,
Derek, using gas in its liquid phase is the best way to keep a constant pressure in the tank, I would not trust the vibrations of the engine to prevent the freeze as my boiler needs a lot of gas. A long heated pipe, a large filter prevent me to install a secondary line to start the heat, tis is good news and I thning I will repeat this on my other boats in which the gas tanks freeze.
Calin, The Anton Trophy races are usually run during the Atlantica Steam event or the Vap'IDF event. None of them were organized last year, you know why, and we hope that the next Atlantica Steam event will be organized during the last week-end of Seprember at Cabariot en Charente 17430, close to Rochefort and its royal rope factories.
