What is the lift of 6 foot version?

don't know, never measured and it is about to get replaced by a new version.... sorry that doesn't help much. I'd guess in the range of 20 lbs or so...it isn't a lift bag and I don't recommend using as such

What is new in new version?

less welds so stronger, smaller opv so smaller when rolled up and a much better clip attachment. plus doing a smaller 3 ft as well

When will the new version be available?

Volume of a cylinder = Pi * radius squared * height

You can calculate the radius by measuring the flat width of the SMB: flat width * 2 = circumfrence / Pi = diameter / 2 = radius

Calculate the weight of that volume of fresh or salt water, and that's roughly your lift capacity (to be accurate you should subtract the weight of the uninflated SMB and the weight of the same volume of air)

Another way to do it is fill the SMB with water and weigh it

The HOG SMB looks kinda skinny so I'm going to guess 6" across when flat = about 30# of lift

NB Lift is only generated by the submerged portion of the SMB

Unless you fill it with trimix.

You forgot one nit picky detail. Measuring the sausage limp will not give you the same measurement when erec...inflated.

You will need to inflate it and then measure to get an accurate radius.

You must be thinking of a different kind of sausage. This one does not have an elastic skin so his method of calculating the radius based on measuring half of the circumference is fine.
