    Thanks

    You would not steal a wallet so don't steal people's livelihood.

    They're called 'anhedrals'. In the case of the LA's they have attached to their outboard ends removable canasters that hold 'evasion devices'. They also produce a roll force counter to the inboard roll produced by the sail during high yaw rate turns.

        Maybe this helps with placement,
        If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.
