aluminum boat

Hello to all,
Could somebody tell me which is the approximate weight of aluminum as the construction material in the 30' motor boat?

 

I think that it really depends on the application (what will the boat be used for? what is expected of it?), but I think at a minimum you would want 0.250-inch for the bottom and 0.125-inch for the rest. It also depends on how the boat is built - if you have a lot of good structural ribs, etc., you could probably get away with a bit lighter gauge.

 

You should go for Aluminum 5083-O

or Aluminum 5086-O

Density of both is about 2650 kg/m3.


P.S. (sorry for you other guys...):

depends on your speed requirements and sea state fast boat at sea, in good sized chop, I would plate in 8mm the bottom with 5 mm, full length girders, for slow boat, 6mm
I would use 5 on the topsides, and 4-5 on deck and 4 on superstrucure
your bottom is critical you can pm me and I will send you some drawings, I have built many al al yachts and motorboats

Ah, maybe I have misunderstood the question... He was talking about the weight, so I gave him the weight.

 

yes I was talking about the weight (measured in kilos or pounds)
thanks to all anyway!

 

Hvala ti na pomoći!

 

For 30' planning powerboat the weight of hull, deck and cabin structure designed to ISO12215-5 will be about 1800 kg.

Thickness is likely to be 6 mm at bottom provided that bottom panels are about 300-350 mm wide. For rest of structure thikness is about 4 mm. These data not for construction, just for quick reference

 

thanks Alik!
