More than 30 boats arrived in the initial wave and totaled up to 50 by year's end and mostly finished up in January of 1987.
Although of a similar type, there were distinct variations among the various boats.
Jinkyu Maru No.18 JNBT, 299 grt/75 Takahashi
Shoshin Maru No.82 JRWE 299 grt/77 Niigata
Shoshin Maru No.83 JGJD 344grt/79 Niigata
They all had the wheelhouse raised a half deck above the boat deck.
The newer boats had the wheelhouse raised a full level above the boat deck.
Shoshin Maru No.85 JGQG 344 grt/80 Niigata
As we now know the Japanese decimated the tuna population and as they did so the number of boats diminished, and we rarely see them anymore. They require different licenses now, and are restricted to ports that they can use, so they can still be seen in St.John's and St-Pierre but not in such great numbers.
