Hi all. My wife and I recently purchased a Hanse 470 in France, so we are new to the forum, but we look forward to sharing with you. My question here is related to the spreaders. We recently had an issue that wattanted having riggers go up the mast for an inspection. We’ll share more about that we we have a clearer understanding. In the process of inspecting the standing rigging, they found a crack in a spreader near the base. They tell us this is a common problem with the design due to the small amount of material between the inner pins and the inner edge of the spreader. So, they say, we should address this issue at all the spreader to mast joints. But, I haven’t yet found any posts regarding spreader problems on This forum. It seems like I should if this problem is common. Has anyone had I heard of similar problems. We will appreciate any feedback, |

Hi, I had to replace all my spreaders on my Sparcraft mast one year ago. Cracks where found on both spreaders on starboard side.   ------------- Lykke, Hanse 430e, #8 from 2007 |

Thanks for the info and pics, Lykke. One of ours is cracking at the same spot as yours in one of your pics, though not nearly that bad yet. I was really wondering whether we really needed to address all of them, or just the one that's cracking. Looks like doing them all might be wise. Thanks again

Welcome, Hope we can all help. I had an issue in our 2008 model https://www.myhanse.com/rig-tension_topic6786_post54325.html?KW=spreaders#54325" rel="nofollow - https://www.myhanse.com/rig-tension_topic6786_post54325.html?KW=spreaders#54325 is an article of mine having had a similar experience. I replaced the one and I've not had a reoccurance, whether it is incorrectly tensioned standing rigging or too many accidental gybes only a metallurgist could say. ------------- Jon B 470e http://www.norse-king.blogspot.co.uk |

i have a 430e that i just bought. it had receipts showing work done on the spreaders and that the mast had come out 2 yrs ago along with new standing rigging but after my purchase i thought i need a rig check and quote to do a few things extra i wanted to do such as single line reefing and a proper german system with 2 line 1 for port and starboard. Turns out theres a crack in the mast between the rivet on mast and the spreader piece that the spreader fits into and then the spreader is peeling away due to movement. Photos below- The rigger proposes repairs as per other photos below. ANy feedback would be appreiated . (Pittwater Sydney Australia)
Trying to upload pictures but its very difficult to get to the right size. more to come

This is what I wrote in my earlier ‘lessons from a refit’ post on the H400 that might be relevant: The riggers noted several deformities on the mast tubing around the Spreaders. This was wear & tear caused by cyclic loading at sea and basically, the areas were just worn out. It required the fitting of ‘mast doublers’ [with new spreaders] to ensure the structural integrity of the mast but the cost was a painful £3500. However, that was nothing compared to a sudden failure of the mast at sea. Recommend that owners lower masts at least every 3-4 years and have a thorough check by a professional rigger.  ------------- H400 (2008) 'Wight Leopard' Gosport, UK |

Hi I have yet to experiance trouble with the spreaders or mast tube like Ratbasher. (Sparcraft Hanse 370) But I have some observations that could atleast explain the failed spreaders. My boat had started it's life in the Netherlands where it is custom to not unstep the mast. Here in Denmark we often unstep the mast every year. I notice that the dogbone (thing that holds the spreaders) are made from some exotic alloy and that it also holds a stainless shroud. Because of this mix of metals there is a lot of corossion taking place inside the spreaders where it sits against the dogbone. My solution is applying Mast Oil (eg. Hempel Alu Protect or similar) to the inside of the spreaders. This has stoppede furter corossion. I would guess a bad gybe or bad rig tension combined with years of corosion inside the spreaders would lead to fatigue and sudden failure.

Ratbasher, yes its very expensive, ive been quoted to take away the normal "dogbone' system and replace with the system shown in the 2nd photo above. Its going to cost approx $10k. Plus im getting a new boom (selden) to replace the existing sparcraft one thats been bent and repaired with plates on each side and gooseneck. Apparently the same as you Ratbasher the spreaders and 'dogbone' have been moving around and become loose, the spreader has started to peel around the dogbone and the hole that the dogbone sits in inside the mast is getting bigger. I really like the solution for the spreaders and i'll feel much more confident sailing in high winds. The new goose neck will be similar in that it wraps around the mast ,again a much stronger solution. ------------- Sydney Australia GODS COUNTRY |

Jeez - 10k is really stretching anyone’s sense of humour. At least the upgrade will give you that all-important confidence when the winds and seas are high. Unfortunately, if your boat is anything like mine it just means that the gremlins will shift targets…. I like H8jer’s suggestions about corrosion, though. I also strongly agree with your replacing the Sparcraft boom with a Selden as well; I’ve become seriously dis-chuffed with Sparcraft recently. As H8jer also points out, the overall message is that it’s essential to do proper rig checks, and the only was to do those is to include regular mast unstepping. Like me, I’m very glad you discovered the issue the easy way rather than suddenly at sea. ------------- H400 (2008) 'Wight Leopard' Gosport, UK |

Hey assieagnus On your picture it isn’t very clear to see the brand of your mast and spreaders On the moment your boat was build (2008-2010) Hanse change from Sparcraft to Selden and back again those years. I believe it’s a Selden mast, but when it is ,I think there’s already done some repairs (good our not?) On the Selden mast C and F sections the attachment of the lower and middle shrouds are integrated in to the spreader attachment and there’s now bolt our a reforce plate in the mast your pictures show bolts and some kind of extra reforcement and the shroud attachment is like on the lower picture of Selden C-F Section mast’s The example picture you show from the rigger :the middle and lower shrouds are lower attached to the mast??? This is picture of the Selden Section C -F mast-Spreader attachment  ------------- Wild and Wet Belgium 545e#268 |

Just to add my experience: last year I had to replace one of the spreaders (see photo). I never understood what happened… ------------- |

Mast pumping?? Close to the wind in to the waves in heavy sea the Hanse mast setup ( fractional afterwards spreaders with pre bent )The mast start pumping in the upper part , the section between second and in our configuration (3 spreaders) the third spreaders. This give a lot of back and front wards force on the lower spreaders. In my experience: trimming the backstay and keeping up some main (we have 3 reefs in by windy conditions) to support the mast. A babystay and running backstay’s will help to IMO ------------- Wild and Wet Belgium 545e#268 |

20 years ago a sailboat with jib only in heavy weather with fractional rigging like our hanse' with 7/8 lost it's mast and ended up destroyed against the pier in my old harbour. The experts (John Mast danish rigger https://www.johnmast.dk/about-us" rel="nofollow - https://www.johnmast.dk/about-us ) said the reason the mast broke was because with a frational rig you need the Main sail to stabilize the mast. When being lazy and only using the jib, the wind must be below 16 knot in my opinion.

 Hi Wild ,no the second photo is what my rigger proposes to do. The 1st photo is the only one of my rig the second one is of another boat that had the same issue. I'll try to post a photo of my rig And yes the new set up will have the shrouds attached below the sreaders not from the spreaders. ------------- Sydney Australia GODS COUNTRY |

 What’s the rigger gone do with this crack in the mast?? ------------- Wild and Wet Belgium 545e#268 |

So it will be repaired and have a strengthening plate put inside the mast and then have the wrap around system installed so it wraps around the mast and has new fixings just as shown in 2nd photo. And the shroud will be attached to the mast lower down. God i hope this is the right thing to do but ive had a 2nd and 3rd opinion and theyve ratified it. ------------- Sydney Australia GODS COUNTRY |
