What about two lw hulls, each with two bows and say 16' long, joined bow to bow with a Wharram type rudder lashing? Not the most smooth of hulls but usually there is non-laminar flow by midships plus many boats have lots of turbulent making bits hanging off the hull. Would be no worse than a boat with a bit of weed on the bottom? Obviously not a racing setup but adequate for mucking about and cruising?
