Hello All,
I ordered my new 400 with a standard propellor, allthough I always sailed with a Gori, on a Grinde, Dynamic 37, and a Bianca 107 due to the displacement of the boats, never more than 6 tons. The Hanse 400 will probably be a little less than 10 tons with filled tanks and all gear, and I cannot believe that the 40 cm2 of the blades influence the speed of the boat. Did any of you experience the difference?
Thanks in advance...

I guess I'll add to the selections here. I have a Flex-o-fold 3 blade which I like. Easy to dismantel and clean and seems to work well. Your real question though is weather it is necessary. I have been told by some knowledgable sailor friends that I would get better engine performance with a fixed blade prop and the amount of drag is minimual. Since I have never had anything but a foldable prop, I really can't verify this. I think the selection may be your use of the boat. If it is for cuising, I would do a fixed prop. If you plan to race, I believe everyone would say go with one of the better folding props for the extra 0.1 Knot speed advantage. Mike

There is a similar 400 in our harbour, I'll check his propellor. Hope it's a foulding one. As soon as possible we'll compare the behavior of the boats.
Then I will report to you all.
Thanks for the support so far!

O, forgot the mention, Bodo's 400 has the old keel and the standard North cloths called sails.
Very curious how your boat will perform with the T-keel and you also have better quality sails?? Rob ------------- "Coriolis" H350 #045 (ex Waarschip 570 #? 1987/1992, ex Waarschip 28LD #7 1994/2007) |

If you are in doubt if a folding propellor has advantages I suggest that you read the test from the yachting monthly via below link. It is very interesting.

Coriolis, I have the standard North Sails, just cause I thought that North only makes quality sails, you seem to doubt that. I ordered a Elvstrom Gennaker though, with a flat cut, I am no square meter freak, but rather a trimmer. This gennaker is 24 m2 smaller, but a good reaching sail.
Thanks Lukemi, the diffrence of 0.1 knot will be a reason not to buy a foldable prop.
Finn, this is usefull!!

You just cannot beat the performance, price and service of Kiwi Propellors, the best feathering prop choice for Hanse. I've had one on my 370 since 2006 and love it!

Have the Gori 2 gear propeller on my Hanse 400/2008. It has some advantages to change the gear and do same speed at lower rpms say cruising at 7,7-7,8 at 2300 in. Top speed around 8,2-8,3 approx the same with either low gear 3500 rps or high gear 2700 rpms.
Disadvantage is moneuvers in the port, where you cannot judge whether in low or high gear, and u could feel lack of power if the blades are switched to high.
Today believe I would go for a flexofold 3 blades to avoid above problem - which speed you make with a flexofold pls?

Must agree with Silversailor on his views on the Kiwi prop.
I've used it for 3 seasons and it works great. Very little resistance under sail, good speed when motoring (maybe a perfekt folding prop would get you 0.2 knots or so more, due to the shape of the blades), excellent stopping power and no prop walk. And for a great price

hallo!
I have a yanmar 40cv and my propeller is a flexofold 3 blade assembled in site. attention because as for as the engine warranty is only valid for propellers recommended by the motor factory. or is it not?

A young lady complains to the car dealer that her car engine broke down: "and you must know that I am a vey careful and conservative driver - imagine I never switched to 2nd gear in my life".
IMHO if an engine fails because of overloading - either by a wrong propeler or by pushing the engine too much or by letting the boat to be full of barnacles this shows and the engine manufacture will refuse to repair under warranty. ------------- Panos Hanse 630e - selling her - |

| I probably haven't be able to properly explain my opinion. I think that the engine (sail drive) could be no more under warranty if you install propellers that are different from what is recommended by the engine factory. Sometimes it happens even if you use any gaskets different from the recommended ones. |

Hi,
And what I mean is that if you overload the engine, no matter how, the warrantee is of no use. On the contrary, if you install a big propeller but use it wisely and the engine fails- not from overloading but from other fault- the engine will be repaired under warrantee. This is of course only my personal experience. ------------- Panos Hanse 630e - selling her - |

Hello everyone,
Here is a new Hanse 400 owner signing in. We sailed the boat from Greifswald in July. A great boat, so far everything works fine.
I ordered her with the standard propeller but I'm planning to upgrade to a folding/feathering this winter. Options are many, finding the right mark and size might be challenging and some screws have degrees, an angle of attack of the blade, instead of pitch.
Now she gains 6.7 to 7 knots with 2400 revs (Volvo D2-40 and S130). I quess she could do better with a bit more pitch, what do you think ? ------------- Hanse 400#803 s/y Saara |

I have the standard 2-blade fixed prop. It has plenty propwalk and when I put her in astern it takes a loooong time before anything happens.... Did anyone of you changed from fixed 2 blade to kiwi or flex-o-fold, and what is your experience? ------------- Hanse 400#655 |

I have the 2 blade flex-o-fold on my 370e, and it takes a long time to start going in reverse. I feel it is slightly under pitched, as my engine revs out to 3600-3700 rpm. Having a higher pitch might possibly help in reverse although I wouldn't count on it. If I had the choice I'd be trying a three blade prop. ------------- Tim AnnSea 370e #418 |

With the greatest of respect to forum members so please do not take offence
Nobody seems to have answered Eva Luna's question
As I understand it what he/she seems to want to know is- has any one gone from a fixed to a folding prop & if so what was the speed difference. Not what prop each of you have or what you would guess would be the speed difference!!!
My experience of .4-.5 knots at 5+ knots is on a 311 using a 2 blade Brunton auto prop & an extra .3-.5 litres per hour fuel used by the autoprop over the volvo fixed plus poorer motoring performance with the autoprop & finally poorer manouverability in the marina
I cannot afford a 40 so sorry Eva Luna - Cannot help

So I went and bought a Kiwiprop. Last summer I had a fixed, two blade Volvo propeller; 17 x 14. With that the boat steamed 6.7 to 7 knots with 2400 revs. The new prop is a 3-blade 17 x 22 deg. I'll let you know more as soon as I manage to test it (next month?). ------------- Hanse 400#803 s/y Saara |

Then I have replaced the 2.blade fixed 17 x 14 with 2-blade Flexofold 17 x 14 There is less vibration and the speed has encreased. I have the same speed with 200 - 300 less rpm. ------------- Hanse 400#655 |

we have replaced with a maxprop feathering one. In my opinion speed difference is between0.5 and 1 knot. I know some test reports specify litle difference, but to our experience the difference is really inetresting. With the feathering prop i got an impressive backwards power, better than with the fixed prop.

Yanmar says that you should keep the transmission in neutral when sailing. But since it was noisy listening to the prop spin, I always put it into reverse to stop the prop from spinning. Yanmar says that putting the shift in reverse could cause excessive wear of the cone clutch. I didn't want to spend the money for a new prop, but wearing out a clutch or two over the life of the boat was less appealing. After a lot of research, I went with the Flexofold 17-13-3L 3 bladed prop recommended by the factory. After three months of use, I am very happy with the decision. The boat has the 40 hp Yanmar with the SD50 saildrive. Full throttle is 3000 RPM's with a speed of 9 knots and about 7.5 knots at 2400 RPM. The boat also has a lot more thrust when it is first put in gear, forward or reverse. It is hard to gauge any improvement under sail but it can't hurt especially at higher speeds since drag increases by velocity squared. And it is quiet under sail with no clutch wear.

Even though it's an old post it's still very hot so I'll add my experience: I have a Variprofile 3 blade, and it performs really well, even though it's hard to make comparison as every single boat is different... Anyhow I've tried it in rough seas and winds and I was never disappointed! I'm a bit curious anyhow on top motor-performance of your 400's... At cruising range (2200-2300 rpm) with the volvo engine I'm doing some 6.3 knots.... I've heard here 7.9 knots at 2600?!?!?!?!?!?!? What a dream!!!!

First season with my new Kiwiprop. It feels great, stops and manoeuvres the boat much better than the original 2-blade fixed prop. Also gained 0.2 knots steaming speed. Maybe sailing speed as well... My log exaggerated 0.7 knots (10%)! I needed to calibrate it with GPS, so this may be a reason for varying speed measures on this forum.
We now get 6.9 knots SOG @ 2400 rpm. ------------- Hanse 400#803 s/y Saara |

Check out this website: http://www.psychosnail.com/BoatSpeedCalculator.aspx The 400 has a static waterline length of 35.4 feet which will yield a displacement hull speed of 8 knots. But is the waterline length increasing as the boat is under way? It sure looks like it when you look at the stern. This website also has a correction for displacement/length ratio. I believe the DL ratio for the 400 is about 220 which yields a hull speed of over 9 knots. If you believe these formulas, why are we going so slow? ------------- Rhode Island, USA Hanse 400, #456 |

| On the subject of Propellers. I have a 3 blade Kiwi prop on a Hanse 400 and my best motoring ahead speed in flat water is 6.5 kn this seems slow according to recent reports from members. Astern or sailing its great. There has been wear seen where the blades hit the boss and its suggested I replace the blades. I am in a quandary about doing the work (as its only been installed 3 years) or going for a more durable Flexofold 3 blade prop. Any members have a view or should I just get the blades replaced this season. What pitch have other 400e owners had the Kiwi set to? |

Three year ago, I changed on my H370e my factory standard three blades flex-o-fold folding propeller with a three blades kiwi prop. (Yanmar 40HP engine, on SD50) I could’nt verify the engine speed ahead comparised to that with the previous prop, but my feeling is that the new propeller give the best performance on reverse. If somebody wants to change his fixed blades propeller with my flex-o-fold, I can sell it. Diego ( mailto:diegoro@tiscali.it" rel="nofollow - diegoro@tiscali.it ) ------------- Diego |

I just wonder why you felt you wanted to change from the flexofold to the kiwi prop. I have decided to keep the kiwi at least for another year. I will let you know how I get on as it is having new blades fired. Thank. Alan |

Hi, I have a 2007 400e with a 40 hp yanmar and a standard 2 blade folding prop. I can get 6 knts @ 2000 rpm and 8knts @ 3000 rpm. Is there someone in the forum with a similar boat with a three blade Gori prop as the local dealer is adamant that is the way to go. Your thoughts and opinions would be appreciated.

The max rpm of engine are 3000 rpm, if you have 2600 m max your propeller is not correct and the engine is in over load.Please inform me the cruising and maximun speed including hthe rpm , because i want chage the prop wth flex. And i want verify the proposal of factory Thank you |

Because of other boat expenses (I changed my whole old battery package at the end of 2012 year) I decided to sell my H370 factory standard three blades flex-o-fold folding propeller, four seasons used, in excellent conditions, with a new anode.

Hi, I have a 2 blade folding and when we feather it it makes a huge difference to the drag on the boat.
