This is the board I am working on now. I'm about a day's worth of work into it. I'm not concerned about the weight as much, but I'm shooting for less than 13 pounds. I'm building it out of solid wood this time--walnut and mahogany--because i like the way it looks. More framework=more support, slightly different rail shape. Concave nose that flattens out into a slight V at the tail. Walnut is such a strong wood, I might skip the cloth this time.
Check it out so far.
