I just add some more, in my design the static LWL is always shorter, by purpose, then what could be and this because when the boat start sailing, the heeling produce two phenomena, one due to the hull shape that tend to elongate the dynamic LWL and one, not always considered by the majority, is that under wind pressure on the sail, there is a vertical component force that push down the hull in the water. Some volume in the front could be also useful.
According to my friend Pierre calculations, at 30° of heel, the boat may sink and increase the displacement by about 12.5%.
It is thus very convenient to have shorter LWL at the begin and buoyancy reserve in order to reduce also the wet area with low windy conditions.
The sharp cut transom may offer some advantage at the condition that a high speed is obtained. By high speed I intend a VR above 2/2.5 and more.
Our models, pertaining to the heavy displacement category, very rarely may reach a Relative Speed above 1.3/1.5
