Description
Research on the sea floor
In Aquazone the Hydronauts were the scientific faction, exploring the ocean bed. A search submarine fits that role: it looks, finds and brings discoveries to the surface. The set suits anyone who likes underwater themes and would rather build a research vessel than a warship. With 298 pieces it is compact enough for a relaxed build and big enough to carry a small crew inside, which keeps the finished model from feeling like a toy.
Black, yellow, light grey and trans-green
The main colours are black, yellow, light grey and transparent green. Black and light grey form the hull and machinery, yellow adds signal colour, and the transparent green looks like water or a canopy. With 88 different part types among 298 pieces the variety is high, which points to plenty of special parts and a model with visible detail. The mix gives the boat a serious, investigative character rather than that of a plain toy box.
Four figures on board
As many as 4 minifigures come with the set, a sizeable crew for something this size. That leaves room for roles such as captain, diver, scientist and engineer. If you want to show the boat off, you can arrange the figures around the model. Their names and exact equipment are in the catalogue data, not in this text. Together with other Aquazone sets, a scene quickly appears in which explorers and rivals meet below the waves.
Parts list and collecting
Every part with its colour and quantity is in the parts list on this page, handy for comparing with your own stock. With the “What can I build?” tool you can see which sets could be rebuilt from your bricks together with this one. For Aquazone collectors that is useful, because transparent and special elements from the late nineties are not always easy to find, and a complete overview saves time when you are searching.
