Yes

Yes, I think that the fundamental variables are:

A) Open - Cabin/Hut - House - Mansion

B) D/L

C) Sail / D

But honest "Sail Area / Tons" and no this joke:

Sail area-displacement ratio - Wikipedia https://en.m.wikipedia.org/wiki/Sail_area-displacement_ratio

 

In my opinion 6 meters, 19.64 feet and 1 Ton is simply perfect because you get a sailboat that hoist 30-20 square meters per Ton

The Dinosaurs are insufferable because they hoist 10 square meters per ton, and downwind as the headsail does not have a boom is the equivalent of about 7 square meters per ton or even less.

On the other hand below 6 meters LWL the D/L ratio worsens if we want a cabin/hut, great freeboard and very good ballast

 

The bow of this sailboat imitates those that reach 30 knots of speed when descending a Big wave

I don't know if this one will achieve it, what I mean is that you pay a fortune to recreate the sensations of a dinghy

"Fandango"

 

I dated a dancing Spaniard for a decade..........memories..

Last cruising boat build had even less than an old UK working boat averages of 100sqft (10msq) per ton. It was enough offwind in a strong breeze, but pretty hopeless in light weather.

Im actually returning to the idea of a smaller boat that can actually sail well, rather than a floating apartment with questionable ability under sail. Catching wind has always been the fun part.

Modernism

Modernism in the design of sailboats is, as the Pope of Rome said, a compendium of all heresies

Modernism in the Catholic Church - Wikipedia https://en.m.wikipedia.org/wiki/Modernism_in_the_Catholic_Church

We, followers of Jakob Amman

Jakob Ammann - Wikipedia https://en.m.wikipedia.org/wiki/Jakob_Ammann

and faithful to tradition, tradition, Tradition ....

recognize within the Minimalist church ...

2) Falmouth Quay Punt, and
3) Canoe Yawl

The modern sloop after 40 years of nonsense can be reconciled with tradition

we reconcile the centers (LCG>LCB>LCF) and we center (1/2 LWL) a 3/4 fractional rig so that the appendage that grabs the ballast is the centerboard

Document sans titre https://www.histoiredeshalfs.com/50%27%20monos/C10%20Aqua.htm

we minimize and even eliminate the low lateral pressure on the stern, we minimize the high lateral pressure on the bow, and with the centerboard neutralized we make several estimates of the Munk Moment and we size the rudder or better said two rudders

A sailboat that can reach Froude 0.5 as a surf launch ramp which means 150 D/L and almost 30 square meters per Ton

modern Sloop (1970-)

Mast: 40% LWL
LCB: 53% LWL
LCF: 57% LWL
Leading edge of the modern Keel: 40% LWL

modern Sloop faithful to Tradition

Mast: 50% LWL
LCF: 57%
LCB: 59%
Leading edge of the modern keel: 60% LWL

 

With the expression 'modern sloop' we can refer to those born from 1970 with the keel and the rudder separated or on a larger scale to those born in 1930 with a fractional rig and in 1947 with "Myth of Malham"

Myth of Malham – Laurent Giles Archive https://laurentgilesarchive.co.uk/product/myth-of-malham/

The curious thing about this story is that "Myth of Malham"carried the mast at 44% LWL

and once the keel separated (ca. 1970) from the rudder... the modern keel moved forward and the mast to 40% as in 1870

The second curious thing is that the trend towards wide sterns and thin bows, a trend suffered in 1880-1890, returned in 1980-1990

That is to say, you can argue this question as fidelity to the spirit of tradition or as freeing and liberating oneself from the blind inertia of the past

 

Note the striking position of Aqua Quorum's Keel

The designer, Adrian Thompson, followed the Primordial Center of the Yacht: the Center of Flotation

 

...

all we have to do is move the rig aft and (with a 3/4 fractional rig) turn the Keel into a centerboard
