Power Block

A new power block recently fitted to the "Argonaut IV". The Power block is powered hydraulics, It is used a bit like a JCB arm with the gray portion a the end containing a wheel which rotates and hauls the net in as it passes over it. Power blocks advanced fishing as it allowed nets to be hauled quickly, which prevents fish from escaping, and allows the net  to be back fishing quicker. It also saved the back breaking work off off hauling it by hand. Its a problem alot of fish species face; that technology to catch them moves quicker than the advancement of their evolution to avoid being caught, will they catch up and pass out the technology ??
