Re: Desplazamiento, lastre y superficie vélica.

Un argumento literario, de la experiencia vivida por Conrad:
To travel along with a cranky ship for ninety days or so is no doubt a nerve-trying experience; but in this case what was wrong with our craft was this: that by my system of loading she had been made much too stable.
Neither before nor since have I felt a ship roll so abruptly, so violently, so heavily. Once she began, you felt that she would never stop, and this hopeless sensation, characterizing the motion of ships whose centre of gravity is brought down too low in loading, made everyone on board weary of keeping on his feet. I remember once over-hearing one of the hands say: “By Heavens, Jack! I feel as if I didn’t mind how soon I let myself go, and let the blamed hooker knock my brains out if she likes.” The captain used to remark frequently: “Ah, yes; I dare say one-third weight above beams would have been quite enough for most ships. But then, you see, there’s no two of them alike on the seas, and she’s an uncommonly ticklish jade to load.”
Down south, running before the gales of high latitudes, she made our life a burden to us. There were days when nothing would keep even on the swing-tables, when there was no position where you could fix yourself so as not to feel a constant strain upon all the muscles of your body. She rolled and rolled with an awful dislodging jerk and that dizzily fast sweep of her masts on every swing. It was a wonder that the men sent aloft were not flung off the yards, the yards not flung off the masts, the masts not flung overboard. The captain in his armchair, holding on grimly at the head of the table, with the soup-tureen rolling on one side of the cabin and the steward sprawling on the other, would observe, looking at me: “That’s your one-third above the beams. The only thing that surprises me is that the sticks have stuck to her all this time.”
Ultimately some of the minor spars did go—nothing important: spanker-booms and such-like—because at times the frightful impetus of her rolling would part a fourfold tackle of new three-inch Manilla line as if it were weaker than pack-thread.(Del "Espejo del mar", claro)
Dado mi bajo nivel de inglés no quiero cometer la herejía de una mala traducción.
Ante esto, que es más marinero:¿Este barco con la distribución de la carga que le dió un GM grande o mejor cargado con un menor GM?
McWhirr:
Ni soy gurú de esto, ni tampoco sabio en el tema, pero me parece que estos barcos más que "blandos" serán "duros" (GM grande conseguido a través de estabilidad de formas)
Salud y buenos vientos
