Interesting concept for the astern mode only ships, just a thought to achieve the ahead mode as most ships seem to steam that way, reverse the polarity on the fan mains supply and get it to run the other way maybe to steam ahead perhaps? That way it would fit in better with the other traffic encountered whilst at sea. Bit of a steep propshaft angle which might lend itself more to submarine propulsion methinks, you know, bow down attitude. Still don't quite see where the anodes live though. You know the ones, the Raritan ones. ( Indian Tribe ones ) I have to confess in writing I have seen that airflow system on deck before, when the log/GPS/sextant/etc system packs up you can tell by the tune played on the pipes exactly the speed attained. Should you hail from Scotland and be a bagpipes fan this can, in certain cases prove to be a distinct advantage. Maybe have to draw 33 inches of vacuum to go astern though, could present a bit of a problem in a blow and crosswind applications. Wondering if you supply a three phase supply and tap off one positive input only if any advantage could be attained on days when the QNH and QFE readings were reduced. Just a thought. Well anyway, keep up the good design work, as a further point of interest just got my old CE books out together with my old slide rule and have worked out that your attempts to beat the worlds fastest attained crash dive could soon be realised. In conclusion I might add it would appear to have something in common with a lot of management out there at the moment, rudderless?
