Another one..

thanks for the info rancho, this would be very useful i've really appreciate it. tell me i had a spreadsheet here regarding this issue. I've have some doubts on the density (mark in red) formula cell. Could you kindly help me beacuse im very new to this type of system. The person who make this had already left and not much information was given.

The weight pro square meters is as follows:

Hull > 1m x 1m x 2760kg*m^3 x 10mm = 2760 kg*m^2
Keel > 1m x 1m x 2760kg*m^3 x 20mm = 5520 kg*m^2
Sup > 1m x 1m x 2760kg*m^3 x 7mm = 1932 kg*m^2

This means that the estimated weights are besed on the following thickness for a gamma aluminum = 2760 kg*m^3

Hull > 10 mm
Keel > 20 mm
Sup > 7 mm

OK?

Thanks, and it looks alright.

OK?

Ranchi, 2760 kg/m2.....?
Cheers.

Guillermo is right...

Hull > 27.6 kg*m^2
Keel > 55.2 kg*m^2
Sup > 19.32 kg*m^2

sorry.
