Hi all,
I got this item from SVB: Is this one good enough to keep gennaker (about 100mq) sheet with a good block? I read about other different ways to do that (dynema loops to the cleat, stern pulpit ring...) but still didnt figured out which is the best.

And what about sheet lenght?
I was thinking to a 10mm...has anyone tried a 8mm?

I wouldn't take the cleats since they only hold 130kg. They will move with force just forward. I'm using the rings on the pushpit without any problem.
For the sheets I would take tapered sheets. I have 9mm on 6? mm. An alternative would be 8mm which is even in polyester far enough for Spinnaker or Gennaker sheets (be careful, we are not talking about the guy! where I have 12mm Dyneema). For the length I would take 2x boat length. I can remeasure when I'm back on my boat.

You should NOT use these for your Genacker sheet. The load is way to big. Use the ring in the pushpit and use the SVB stuff for a set of barberhauls. Works fine on my Hanse 400 both for the 140 m^2 gennacker and the 90 m^2 code1.

I do not know about other Hanse models, but having had a pulpit failure (as have others) I would be worried about putting loads on the pushpit.
When my pulpit failed, due to simple strain from the guardrail, I found that the posts had only 6mm studs welded to the bases. One of the studs had an 8mm nut on it which some lazy worker had just pushed on bedded in sikaflex mastic as he was too lazy to get to the awkward position to fasten the correct nut. If the pushpit has a similar fastening then one should be aware of how loads are applied or at least check first. |

Many thanks for the answer...I was thinking the same. I will try pushpit rings and refer (after checking bases and nuts...). Using only Gennaker I wont need any guy! I will save Dyneema money for something else (barberhauls)! |

HI,
gennaker halyhard is on top of the mast or on jib exit? I have it exiting from top and down to a ring on the front of the mast at the black sign.

You will need to put a block on the ring and feed the halyard through block.
If you use the block the halyard will chafe and fail very quickly. Simon |

suggest NOT to Use rings on pushpit. I did That on my Hanse 400?- and the rings broke.
So did the Genakker platform. My Genakker is 135 sqm and the forces in 8/10 m/sek is evident. |

Purchase or have made up 2 dyneema strops 250mm long, place these through the center of the rear deck cleats and attach your blocks with snap shackles.
This give you the strongest mounting point for your blocks and also means you can remove and store out of the weather your blocks when not in use. Pic is off net which is one of myHanse regular contributors Johan, he has used webbing as an alternative to dyneema strop but principle remains the same.
