We have not found a reliable source on where Chang Se Gi Co., Ltd is based or how long it has built boats, so this page sticks to what the model records show. The programme is made up entirely of inflatables, from small tenders to boats for an outboard. Each name combines a series code with a number that almost always gives the length in centimetres: a CLS300 is three metres long, an RGD520 5.2 metres. The builder's plate alone tells you series and size.

Our model records list 28 models, all inflatables. Build years run from 2001 to 2018, and none is still in production. Most series end in 2008, two SENS models continue to 2010 and the Sens 390 to 2018. Lengths range from 2 to 5.2 metres, with half of them between 2.6 and 3.9 metres. The TEN, CNB and CND boats are around two metres, the CD and CLS models 2.4 to 3.3 metres. The SENS series has six models from 2.65 to 3.9 metres. Larger are the Star, the RFT and the Pride at up to 4.7 metres, while the RGD series spans 3.2 to 5.2 metres.

Boats like these serve as tenders, fishing platforms on lakes or quick runabouts along the shore, usually with a small outboard. Their value lies mostly in the state of the tubes: seams, valves and the fabric itself age with sunlight and storage. A boat kept dry and folded in winter holds its worth far better than one left inflated outdoors, and the engine often accounts for a large share of what the whole package is worth.
