Hi Ian - The Euronaut has the bolted frame in the machinery space. 
The Additional battery, gas or whatever section has a diamter
of 2,5 meter a length of 2 meter and a weight of 9,817 t with
a displacement of 9,817 m3 ;-) The boats move from 16 to 18 meters
is I decided somedays to add them. 
If I add them it will be surprisley cheap - and to plug in 
the ready build section will cost me a weekend or two..

Warrend - you keep out the bolted section frame  - but it looks like on
the list that most guys like it - for what reason it moves out ? 

The only reason I can see is maybe the additional price ? 
You can save so much building time - work in this saved time regular
and you save money with the sectionframe..

Modules length should not terminate like 2 meter and 4 meters. 
The modules can have different lengths depents on what they contains..
The just have to have design to a formular like 1t = 1m3. 
Please note that with the additional section the boat lost a little
freeboard.
