This boat is used for seismic exploration using acoustic probe in the sea. The 1 km cable is unloaded with the winch and pull in the sea, where the end probe can move to adjust its direction and depth and communicates with the boat directly though the cable. After the data acquisition, the boat use the telescopic cable lifter and the two flaps to lift the cable from the sea to wind back and get the probe. The cable lifter can also be equipped with fixed acoustic sensor (displayed on the LEGO model). You can see the real boat in action here.

Some history about this model

This model was designed in 2022, based on Jenmar Norpower boat with Sercel Livery. The aim was to display in a showroom to show the functioning of the boat. That is why it doesn’t float and is not motorized.

It was nevertheless quite a challenge to reproduce the boat, especially the hull and the colored decks with all the details, as well as the seismic specific functions to be functional without affecting the sturdiness of the model.

After some demands and good feedback on the overall design, I decided to make the PDF instructions as it can be easily modified to accommodate other purpose such as fishing, rescue, research etc.
