The hulls are steel and heavy and the rig probably barely proportional for her size. Despite this, and in the absence of any self steering and rig adjustment for her aspect to the breeze, she got along at a fair old pace. I trust that this is a reflection of her hull shape. The almost complete absence of heel means there's virtually no spill as one would get with a mono-hull so in a real life situation the rigging must take an immense hammering when there are gusts - of course if the hull is compliant and the set of the sails is good then the hull speed should shift considerably - such compliance safeguarding the rig to a degree.
Of course one can have hefty rig or just be vigilant in easing it in gusts and blows.
What I did notice was that when the breeze was stronger and more aft that her nose dug in somewhat. naturally more on the lee hull, and this despite having most of her buoyancy forward and with her rounded nose.
How much more would this have been the case had the bow been fine and the bulk of the buoyancy aft!
One of the prime motives for proposing the generality of the reverse hull idea is that it might be a safer one when running before the weather and sea.
On the pond one of monohulls, well laden with lead ballast, showed particularly good steerage, going almost faultlessly straight when pushed from the shore. When pushed out with the sharp end as the bow there was no directional stability at all. I can suggest reasons for this though I don't know how valid they are.
As the bow ploughs into the water, at that front, there is likely to be a quite a mixed population of eddies and waves etc present at the time and then those generated by the forward movement of the hull, both in the water, at the interface and in the air above these. One would think that a sharp bow would generate less forward disturbance if any at all. But like the keen edge of an axe descending on a block of wood slipping rapidly into what would be the mean of the grain(s) in the wood, the sharp bow with much of it above as well as under the water now finds quickly the mean of the water currents, edies, and any wind above, and the hull mass like the hefty back of the axe head allows those influences on the bow to determine her direction.
In the case of a rounded bow its bluntness is aggravating the water it is entering already, compressing and generally lining up at right angles to itself that population of variant forces and making them one
or less numerous. Cut into them it must the bow now is pushing through this somewhat prepared and now more homogeneous milieu. It parts and such banked up energy as occurs from this parting forms a pressure head, equalish on both sided of the lubber line and as the greatest width of bow curvature passes this it dissipates its energy in squeezing the hull aft of this greatest curvature (width) forward.
I might have said it before but I heard somewhere that perfect hull would leave no wake.
