When we pulled the Air Horn down from the Mast of the Aurora we could tell that it was in very bad shape. Most of the reason was years of improper maintenance. I sent this horn to our friend Joe for some Aluminum Welding and Fabrication and the Ships Air Horn is well on its way to making a full recovery. We did this entire episode with the Power of the Sun using VanPowers Super Power Pro Portable Power Station and 200w Solar Panel and it worked amazing!!!
