Suitability for Offshore work?

[bill@ariel231]

you have it right till the 33/57+ step.... 33/57 ===> 0.57 or so....

Ahh 33 over the 57, i was taking 57 by 33, got ya.

...and isn't the displacement of ships still done in long tons?   2240#
None o this lubberly short ton stuff round haya.

That oughta change a few figures.

I got 1.839 using ebb's numbers....

they also roll like a pipe when on the surface....

let's see what the CCA formula shows:

The capsize formula is: Beam / (Displacement/64) .333 {cube root}

(33 feet) / ((6080 tons * 2000# per ton)/64)**(0.333) = 0.5763... OK I guess it passes the CCA thumb rule.

of course.. this formula was developed for sailboats destined for offshore racing not a general formula for all hull types... just amusing to see how other hullforms compute ....

(33 feet) / ((6080 tons * 2240# per ton)/64)**(0.333) = 0.5527... still passes with the wrong formula and ebb's long ton
