Working on a tuna boat

The tuna boat is approximately 69 meters long, 13 meters wide, and has a draft (part that goes under water) of about seven meters. In terms of mobility, it can develop a speed of 31.4 kilometers per hour, but in terms of fuel economy, it normally operates at a speed of 24 kilometers per hour.
Each boat can make a trip of between 55 and up to 70 days without having to refill its supplies (water, fuel, electricity, food). It has the necessary equipment to find the schools and capture the tuna as far away as they are, but it also provides amenities for its crew.
The crew is made up of a fishing technician, the captain, the chief engineer, pilot, mechanic, boatswain, deck chief, search engine, pangueros, boatmen and apprentices.
