WHO EVER said redundancy was at the core of DIR? WHO MADE THIS CLAIM?! WHO?!! >This >"hogarthian inspired" setup has neither long hose nor redundant air. Nor does it need them. Though I might add a short long hose at some stage, when I've figured how it will lay. >it without the wings, and there's no redundant buoyancy either. True.
