| John Grey is one smart dude... needless to say I agree with almost everything he says (99.9%)   |

| I am half way through re-listening to that Indian guy on the micro-loans most impressive... I like his idea of "Socially beneficial businesses" That is what I am working towards for Melanesia.... - at least my variation on the theme...

| [quote=Hydro Lance;204747]Marshmat said: An estimate based on the Grigson line puts skin friction drag alone from a very well optimized craft of this size being at least 300 kN at that speed, and an astounding 750 kN for a 100-metre, ultra-slim, negligible-wave-drag shape like the Hydro Lance. (Skin friction quickly trumps wave drag at high Froude numbers for virtually all forms capable of achieving such speeds.) Well, "a breath of fresh air" - someone who thinks. All HARTH vessel incorporate a low energy and very effective surface wet-ted drag reduction system. Accordingly, your assumptions of skin friction drag are incorrect. If your company has come up with a novel and effective way to reduce skin friction drag, that in itself would be a huge breakthrough in naval architecture. Why don't you forget about the super thin catamaran stuff and just market the skin friction reduction element of your design? Just about any vessel that goes over 10 knots would benefit from a reduction in wetted surface drag. You could be sitting on a goldmine. |

| After this many months I think it's safe to say the guy's given up on trying to convince us that it works....
