Just completed the design a few months too soon. As we can all see, there is not enough rocker forward. The designer is still using the now clearly obsolete rule that waterline length matters even when displacement is low, or more importantly, even when buoyancy is very, very high.

I mean, everyone who has ever sailed a windsurfer (is there anyone who has not?) knows very, very well that waterline length is not an advantage for planing. In fact, it is the opposite of what is needed to plane well.

Displacement mode still likes waterline length, but only for boats that don't easily exceed hull speed, which means 300+ D/L (remember, a Cal 40 has a D/L of 240). And such boats cost too much per foot, so we don't see such slugs anymore.

Consider the Dufour 430 Grand Large, a VERY roomy condo on the sea. This Felci design has a DL of  170, so even this big modern piggy cruiser will exceed hull speed much more easily than a Cal 40. A stock Olson 40 has a D/L of 99, mine is about 85, and a modern VPLP designed Pogo 36 is 83.

So modern boats should NOT have plumb bows. Only heavy pigs should have plumb bows. Modern light boats should have bows that lift, so have rocker forward, instead of bows that don't have rocker and instead go underwater when pressed. Planing REQUIRES angle of attack where the hull meets the water. Plumb bows are literally the opposite of what works.

As Armel Tripon on L'Occitane en Provence is demonstrating yet again to all those slow learners of the world.

Pogo 36 is a finot-conq design, not VPLP !!!

And if you try sailing a family cruise in one of those scow bow Class 40s, I can guarantee they're so uncomfortable your family will hate you for it !

Plus for all I see, for a cruiser this 56 isn't exactly what you'd call a deep, thin bow. Look at the views on their facebook. They seem to have understood the waterline length thing too...

Fat ass boats with pointy bows are worse, as we all have experienced. For cruising, I prefer balanced over unbalanced, for obvious reasons. Hence my Olson 40.

Also...at anchor the beamy boats roll spectacularly compared to narrow boats which tend to simply rise and fall over wakes and such.
