Note: No Trangias were harmed in making this modification . I am not a sailor, but I know from this forum and others that alcohol is the preferred fuel for cooking on small boats. I know there is a Sterno attachment for use on the Sea swing but I wonder why there are no 'sea swings' for Trangias (unless I have missed reading about them). Since the kettle and pots for a Trangia are semi-contained and secure in the windshield when cooking, I thought it would be relatively simple to make a Trangia into a 'sea swing'. The photos are self explanatory as to how to make it. The first stroke of luck is that 20mm x2mm aluminium bar fits snugly through the strap slots in the trangia base. So two uprights are made using this bar, bent at 90 degrees at the bottom to provide support feet and to enable the Trangia to swing safely. These uprights should be tall enough so that you can get the kettle and the pots in and out of the stove when the ring and cross bar are fitted. The ring is also made from 20mm aluminium flat bar pop rivetted to form the circle, and the cross bar is 6mm steel rod threaded and nutted at each end. This assembly now allows the stove to swing in one direction. A bracket was made from 25mm x 3mm mild steel, being much stronger than aluminium, and when attached to the ring at 90 degrees to the crossbar allows the stove to swing in the other direction. You can of course alter the cantilever 'stick-out' by drilling additional holes in the sides of the bracket. And that is it. The parts can be unscrewed and removed and the Trangia is back for normal use.
Having tested it in boiling water and making a brew, I have made some changes. Reduced stick out on the steel bracket Which is now bolted to a square wooden mounting block fitted on the back with a hanging bracket so it is easily hung and removed. and the stove now swings on a grooved ring so it can be easily taken off. and the whole unit can be removed and dismantled without any tools. I am done with modifications now. Too busy building the boat.
