Having finished two wooden boat/ship kits I feel maybe I can begin this kit that really began my interest in wooden kits . A little info on this submarine . It is named the Yefim Nikonov’s Submarine . Believed to be the first military sub built . Building began around 1718 and was finished in 1721. The first trial was in 1724. It was a disasaster as it sank and hit the bottom and broke the bilge. The builder and 4 oarsmen were able to escape . In 1725 a second was tested and also failed . A third was tested in 1727 and it too was a failure . Not sure I am ready to tackle this kit but I will give it a go . If I run into trouble I will put it aside and build another less complicated kit and get more practice .
