The problem is that the trend is to increase the height of the mast

. Nathan has done it, Roger has done it at Lightwave, Tag are doing it and many others.
When you do this you increase the Centre of Force or the turning torque on the boat so that in the end you have in the worse case situation boats that can fly a hull
at 18 knots such as the Tag 60. The understandable response has been to depower the boat.
This is deemed to be not a problem if you want a reasonable cruising boat with heaps of comfort, but it is a problem if you want exceptional performance. It all depends on your requirements.
In my view the gold standard is the 5X, an opinion with which I am sure you would not disagree, so I take my best metrics from there and compare others to that. On that basis the FF46 is underpowered. Now others may not want or need similar performance to the 5X and fair enough. This is simply my view.
I have spoken to Nathan and he believes the sail plan is adequate for a cruising lifestyle and I have no issue with that. However, I would want to beef it up. Just my opinion.
I have been comparing boats for quite awhile as part of my quest for a real bluewater cruising cat that will sail well to windward and in light airs re performance. I've settled on the FreeFlow 46, for many reasons and performance is one of them. But there is such a thing as a boat being too edgey for comfortable cruising, of that I am convinced. So not too light nor too heavy, not too much SA/D, nor too little. Has slippery hulls shape but can carry cruising payload.
By comparing the FF46 to an Outremer
5X, is is not apples to apples. I just looked up the comparison on multihull
dynamics and for a boat that is 58 foot vs 46 foot, sure it's a faster boat, naturally. BIG stick with BIG sail area. But for a couple to manage and reef quickly in a big blow?
Now compare like with like and the same comparison of the FF46 vs the Outremer
45 shows better metrics for the FreeFlow 46 on almost every item. Better Bruce #, better Texel rating, faster on KSI & yes better SA/D etc etc.
Just saying that a really great cruising design is not an easy thing to achieve, and I was pleasantly surprised to see how the FreeFlow 46 scrubs up vesus the Antares
44i, Catanas, and even the Outremers. Gunboats seem to be in a go fast league of their own
