MINE SHIPYARD MS-50V Used Motor Boats for Sale in Japan

Exterior
The boat is used for longline fishing. It was completely repainted in 2024—including the hull, deck, bridge, and mast—so it looks great. Fender mounts are installed on both sides. The wings are quite wide, which provides stability and reportedly reduces fatigue.
Front Deck
The front deck measured approximately 8.30 m from the bow to the front of the bridge. While there is some wear on the non-slip surface and some paint peeling, the surface isn’t spongy, and the area above the hatch is solid. The windbreak for the longline is made of FRP. A wide black tent is also installed. The large fish hold features an automatic drainage and circulation system. There is no hatch in the ice compartment.
Bridge
A monitor is mounted at the front. It is set up to display either the radar or the chartplotter once the cables are swapped. The Hugal pump and rollers are in working order. The side deck is 60 cm wide. The bulwark is 65 cm high, with a 30 cm wave guard installed on top, making it quite tall. Since the fuel tanks were replaced, there are cut-out marks on both side decks where they were removed. The two tanks combined hold 1,200 L. An air conditioner outdoor unit is installed. A marine toilet is installed inside the wooden box below, but it is not currently in use. The slow-speed device and fresh water faucet do not function. Since they are never used, they are left as is. All radios and horns have been removed.
Aft Deck
The plotter monitor and a degree-based course-setter remote control are installed here, allowing for fine-tuning of the boat’s heading while navigating. The wide awning is paired with a spanker. A trolling remote control is installed here. The fenders on both sides are removable. The steering cylinder shows some rust, but it is currently in working order. A fresh water tank is built into the starboard side of the deck, but it is not currently in use.
Cockpit
The boat is equipped with a full set of instruments, including AIS, a 25 kW radar, a chartplotter, a fishfinder, a current meter, an autopilot, and a triple remote control. The rotating window operates properly. The air conditioner is said to cool well. There is also a defroster at foot level. The space under the floor connects to the battery compartment. The 25 kW radar will be replaced with a different unit. The AT32 wave-making device and all radios will be removed.
Cabin

Isuzu UM6HE1TCY2
This engine was replaced with a brand-new unit in 2015. It has been actively used for longline fishing since then and currently has 15,021 hours on the clock. The generator is 18 kW. The fuel tanks have been replaced with a 600+600-liter setup. The boat cruises at 16–17 knots at 2,100 RPM. Since it often goes on long voyages, the propeller pitch was reportedly lightened; when it was first launched, it reportedly reached about 24 knots at 2,700 RPM. In 2024, the cylinder heads were removed to replace six needles. Consumables such as oil, filters, and the impeller are replaced regularly, but there have been no other major component replacements. A blow-by vent is mounted on top. As is typical of Isuzu engines, blow-by seems to occur frequently.
