Resolved solution? I thought we had that long ago. The resolved solution is that it all depends on your definition of planing. If we take Ian's...
No I can't. However I am sure there are many who could. I made a mistake some time ago on another forum when I opined that spinnakers lift the...
My understanding of the word ****** is that it means masturbater. Since 95% of males admit to masturbating and the other 5% are lying, then we...
Absolutely incorrect. The only rig that has any net lifting effect on the hull is the kite (real kite, not spinnaker). For every other rig,...
jehardiman: "What should we in the design community take away from that observation?" The monohulls aren't really trying. If they were serious...
Great photo's! No cats there. These are built to a rule and they can't build a competitive cat to that rule (they tried and failed). For the same...
One more thing. If a trimaran has one of its hulls not planing then the boat as a whole is not planing, although one of its hulls is. Only when...
It's quite simple really. Ian Farrier has defined planing as skimming across the top of the water. Monohulls have some difficulty planing...
Doesn't the load from the rig ease the load on the beams? Like the windward hull being lifted by the sidestay rather than by the beams.
AP: “The whole argument relates to stiffness to allow forestay loading. I suggest that this is no longer relevant to the cat vs tri question as...
If a video of an F-9R center hull with the bow right out of the water and a power boat like wake/rooster tail out the back is not enough for...
I think Ian says it all when he says: "However, being able to plane (or skim across the top of the water - whichever you prefer) changes all...
Yes it is. If it could be proved that the windward hull(s) create hydrodynamic force greater than the displacement required, could they be...
Skimming across the top of the water, supported by the heeling force, just like the farrier centre hull.
I never doubted Ian's logic nor his cleverness. I never doubted that a farrier centre hull could plane. I even suspect that if the leeward ama was...

I agree completely. Need we say any more?
Quote:One definition of planing is that the weight of the boat is supported by dynamic lift. Since this is not the case, how can the sailing...
