Radical ... but not really.


Recommended Posts

The 75s (68s?) are astonishing in any decent breeze but beyond a very sad joke in lighter airs. Also they are tippy (dangerous?) bastards when even the best crews in the world screw up during tacks.

The solution for next AC round?

Keep the same monohull configuration but dump the beyond complex foil entanglements.

Meaning a true trimaran foiler.  With small floats.

Not much different than present concept.

But no ballast.

And instead of the beyond complex canting mechanism, have alterable angle of attack foils, So the small windward float and foil flies clear. No water drag. Minimal air drag.

Very simple. Very, very fast,  And definitely safer? No?

Far too sensible an idea too cheap too practical and too fast.

Wait what!!??  You actually want the sailor’s skill to determine the winner??  Blasphemy

You could go back to single luff mains on the next AC configuration - but these expert crews and designers have made big advances with their double skin mains. Why drop that new skill information?

Blue Arrow was brilliant but also a brilliant failure too.

I learnt the hard way that you have to have more than just a foil out there to leeward.

Not expensive enough. Gotta keep the riffraff away (sorry s+s).

Very fast - yes. Definitely safer? Hmmm...not if MOD70's are anything to go by.

TNZ seemd to be foyling fyn at bottom wind limit.

I reckon:

Keep bayby, freshen barthworter.

Haz a few  bayby turds oanly. 

Snaerk your hit and miss word salad gibberish pales in comparison to Snaggletooth sharpen your pencil.

There was mention of possible trickle down from the AC 75 in another thread.  I came back with a "trickle down" concept not vastly different than yours.  I am working on a prototype 12' version (using a few of my UFO parts) even now.  Here is my previous description:

Hmmm,

At the far end of trickle down could be a single hander.  A small slender hull boat with two canted Y or T main foils up front might be fun.  Put them on a beam for simplicity, but make them easily retractable.  Put some small floats next to them just so it wont fall over at rest. 

You know, someone with some UFO parts laying around could play with that idea.  But then again it would take having two main foils.  Hmmm.

MOD 70 with locked mainsail sheet; just asking for trouble?

But that system has been improved since those days.

All I'm saying is that you could have an AC75 (with tri foiler configuration) that would be less complex to build/sail and have similar or better performance than present set up. And especially in light conditions. when the non-foiling, heavy AC75s are an unfunny joke.
