Re: Thames tons
Der Einfachheit halber schreibe ich jetzt die Erläuterung von Don Street
aus seinem Buch "The Ocean Sailing Yacht" ab.
Thames Measurement
A "tonnage formula", in general use in Great Britain.
The formula is: ( L-B ) * 0.5 B / 94
where B equals the length between posts, i.e., the lengths between the stem
and the sternpost at deck level. It is used by Lloyd,s Underwriters in figuring
premiums, to the great disatvantage of American boats, which usually are
beamier than the British, as the Underwriters charge a certain amount of
money per unit of Thames Measurement. Two boats can have the same displacement, i.e., weight, yet have a vastly different Thames tonnage
measurement.
Allein die Sprache in der "Don Heineken" diesen Anachronismus erklärt ist
einfach herrlich!
Viele Grüße

Re: Thames tons
Es muß natürlich heißen:... where B equals the extreme beam, an L equals
the length...........
the length...........
