Nimble omnidirectional speed / houseboat

@SailDesign, the OP gave 2 seconds, I know, but Gonzo did not speak in his comment of any time and exposed some reasoning with very little foundation, imo.
I trust your calculations, let's say that you have succeeded, very well, 2.38 G, so what?. What is that for the OP?. What you have to say him is that, for several reasons, that boat is not feasible, whether 50 knots or 5 knots, 2 seconds or 22 seconds.

 

< sigh... >

Whether 2 seconds or 22 seconds makes the world of difference to the accelerations required. And Gonzo had read the original post and assumed we all knew the 2 seconds requirement.

If you feel +50 to -50 mph in 2 seconds is do-able, then please tell the OP how. I'll be interested to see the logic.

 

Could you please re-read my last post?. There is my logic : "that boat is not feasible"

 

What you SAID was

This reads that even +5 to -5 in 22 seconds is not feasible. Which is wrong.

I know that English is not your native tongue, and since I know NO Spanish worth mentioning, you are far ahead of me there. However, your post reads as I state above.

 

THIS BOAT, changing speed IN ANY DIRECTION, is not feasible, imo. Is now my english more correct?

 

TANSL, I'm not making fun of your English - I'm merely pointing out that I may have read it in a way you did not intend.

And if this vessel cannot change speed in any direction (this mythical, non-existent vessel that no-one has designed yet) can we not simply give it a Voith-Schneider rotor and go home?

 

Yes, you are right, we leave him with a Voith-Schneider and we dedicate ourselves to our things.
