This model was designed for fairly easy and straightforward assembly. Part locations are easily identified. Hull sections mate together through the use of integrated bulkhead lipss that reinforce the seam and strengthen the hull. Holes have been created where orientation pins or bolts can be used to secure the hll together.  Hull access is achieved via the removable upper deck, engineered to lock down using a single bolt in the upper rear hull area. 

Printed at the supplied scale (1/72), the boat will end up with a beam of 143mm (5.6”) and a length of 1221mm (48”)
 
The hull will accommodate a cylinder of up to 4.25” in diameter, however we recommend the Nautilus Drydocks 300 Series SubDriver with the 3.75” diameter tank option.
