The hull is very cheap, whether it is a fishing boat or a cargo ship, it is a 20-meter boat, with a weight of 300,000.
However, the hull, engine and auxiliary equipment are not installed, and they should be selected according to the needs of customers. If the requirements are not high, 600,000-700,000 will be almost the same, only with basic navigation ability and low power redundancy (unable to cope with big waves). If we want to go to the ocean, we need to upgrade our radar, electricity, navigation system and improve our living environment. These are all money. There is a big gap, and the low allocation is hundreds of thousands, which is acceptable.
There is also a big gap in fishing equipment. Complete sets of equipment hundreds of thousands, even millions, cheap 10.2 million. The main difference is the degree of automation, deep-sea fishing or shallow-sea fishing, whether it is a cold storage.
Therefore, if a fishing boat can be used for fishing in the open sea, it will be about 5 million, and it can't be lower.
Cargo ships are much cheaper. Besides, it would be a pity if there is no 20-meter cargo ship going to the open sea, the 2 million mark.
