I noticed the differences, but I am a cruising sailor and an extra knot under certain/optimum conditions is insignificant to me. "Racing boat technology" just is not of any use to me.
It has been mentioned that the new hulls are theoretically "faster", how there is less friction, wetted surface different entry angle, etc.....but you have yet to explain how a boat is "faster" than a boat that is sailing at 1/4kt under it's theoretical hull speed.
I explained this in more detail in several posts above, but as a broad generality, the reason that the term, "theoretical hull speed" includes the word "theoretical" is that boats of certain designs can and do routinely break that that theoretical speed limit. The seaworthiness, speed, and motion comfort advances in this design do not rely on "Racing boat technology", even if they do rely on the kind of information that has been learned from the scientific research that was funded by race boats.
If you look at the boat designed with my tastes in mind, it starts with a theortical hull speed that is roughly 1 1/2 knots faster than the Capt Cicero. It has a lot more sail area, the stability to carry that sail area, and a little less wetted surface, so it should be able to achieve that hull speed in much lighter winds than the Capt Cicero. It is a semi-displacement hull form, so in a breeze, it should be able to easily sustain speeds that are perhaps 3-4 or more knots faster than the Capt Cicero.
The design for my taste should be able to get by without headsail changes in winds from nearly no wind up to winds into the high 20 knot range, and still out perform the Capt. Cicero in all conditions, making the newer design much easier to handle in changeable conditions. It should be more forgiving as well.
The taste for boats like these not about marketing, or being sold a bill of goods. The reason that a boat like the one designed for my tastes would be is appealing is that since boats are built by the pound, and its cost would be about the same price as your boat. Since it requires fewer sails, its operating costs may be less. And yet in all ways, its capabilities as a coastal or ocean cruising boat are far greater.
All that said, all that counts for any of us is that we like our own boats. And since you love your boat, that is all that counts for you. As much as I enjoy seeing boats like yours and enjoyed redrawing the lines as a history lesson, yours is not a boat that I would ever be happy owning. But that really does not matter either.
