FC-470 speed tube dia

Could someone with a F-470 tell be the the speed tube approximate diameter at the rear ? I am trying to calculate a ball park buoyancy of the tubes, I'll try to factor in the taper at the bow. Thanks in advance.

Cheers.

Boat's not here but I'd guess at about 6-7".

The only info I can find in the manual is on the main tubes; diameter 1'8" and capacity 1860l or 66cu ft.
