Hi Everyone, I'm back again after another 10 years. Every so often a bit of software comes out that makes me want to sketch boats again. It was Corel Xara back in the early 1990s/2000s then Imagine and Shape from Dassault in 2006-8 and recently I discovered Gravity Sketch. Its aimed at the conceptual stage and has all the basics for sketching lines and Sub D surfaces. Here is my initial attempt, excuse the lack of editing down to a more digestible size . in part 2 I'll show the surface concepts. (Still learning them)
