| Propeller sales and repair of small craft(fishing boat, speedy craft,cabin cruiser,and yacht,etc) Machining and sales propeller-shaft,rudder,marine-goods、anti-corrosion zinc,aluminum.We produced the propeller of Battleship "Yamato" in Yamato-musium too. |
Establishment the58th ! Sales and repair of propeller and machining of prop-shaft of small craft .(cabin cruiser, speedy craft,fishing boat, and yacht)
We have made an effort to come through the guest's demand as much as possible,as a result , we have produced many things.
Please ask me without reserve !
| The propeller of Battleship Yamato (scale 1/10) in Yamato museum are big things to be made by Nakashima propeller for our request |
| NOW New topic is Surface-propeller!! |
It is called "Surface-propeller" and exceeded
50 knots. It's 90km/h or more per hour. Terrible!!
A right propeller is a Surface-propeller of the topic now.
Starting , Cutting-wave , Stability is improved!!
Fuel -cost efficiency UP ! Speed UP!
|
The rotation of the propeller goes up too much.
The rotation of the propeller goes down oppositely.
Doe's it seem to slip ?
Possibly can you speed up ?
We have many various ways to speed up. for example changing pitch、with cup.
But detailed data are necessary. The more detailed data are ,the more correct We can calculate it. Accurate dimensions appear so as to know a lot if I know a lot.
The maker's name of the hull, a model, an engine maker, a model, maximum vessel speed ,the number of revolutions at that time, (maximum horsepower, (maximum revolution, reduction ratio)etc.
You should examine it! register here
We calculate the optimal propeller-size at free registration!
Before
Full-throttle 2600rpm 19knots
After
Full-throttle 2750rpm 23knots
４knots UP ！
Mr.K Kanagawa-prefecture

Satisfaction !
Just 2350ｒｐｍ 1knot UP about 30 knots Satisfaction !
Friend's ship also will wish speed up next time.
The grateful mail reached from Vladivostok of Russia
Thank you very much for your excellent work on the calculation and repairing my old propeller!
The reaction at a dead speed has improved wonderfully.Moreover the acceleration feeling of starting has improved greatly,too.
Today I cleaned the bottom of the ship and changed repaired propeller.
About D720×P975,AR0.55,I thought it looked like a new one with satisfaction though it was corroded terribly
It's speed is 30 knots by 2230 rpm.
Can I ask you to produce of the helm of Yamaha 30S?
I think that a hard tree like oak is good.
