Hi

Have a Hanse 400 from 2006 with the main sheet in the cockpit. Im thinking about moving it in front of the sprayhood.

Trying to find out how it should be fastened, it looks like the boat is prepared for this, but i would need a construction drawings or good information from someone who has done this.

Thanks

Hi Christoffer - and welcome to the myhanse forum.
First a little copy/paste:

(I have mentioned this a few times to other myhansers.......)

Before asking your questions in the forum, use the search function, because maybe your question already has been answered just a month ago, and in this case of rudder problems, there are dozens of post from the last 15 years.

 1) Search

2) Advanced Search

3) Find Posts ------change from 6 months to any date

4) Write your subject: Corroded rudder post,Rudder, mast, battery ..........whatever.

5) Mark "Search Forum" as "All Forums"

And you will find results like these:

https://www.myhanse.com/skdeskinne-p-ruf_topic10273_post86520.html?KW=Sk%F8deskinne+p%E5+ruf#86520

And this link is also included:

If you choose to keep your main traveller system, you can buy a stronger system:

Hi

I cant see that this/that thread answers my question.
Im solely intrested in how to fix the main sheet in the front of the sprayhood, not the benefits or disadvantages of the sailing caracteristics of that position.

Is there just a plate prepaared in the plastic that you can drill and make a thread and then fix ?

Thanks

Chris

There are aluminium plates glassed in during the build. Use metal detector to find them or obtain a copy of the Hanse 400 deck layup card showing the location of the aluminium plates. Again well documented on this forum if you use the advanced search function.

It seems to me, that there is a lot of information in the links, for a Hanse-owner who wants to move the mainsheet system. Move is maybe the wrong definition. The system from the cockpit can not be moved to the front of the sprayhood, you will have to buy/make a new, shorter model. This is also shown in the last link. It links to Marcos homepage, where the drawing of alu-inserts positions also are available. Wesailhanse.se has a lot to offer for sailors who do not yet know their Hanse.

I may advice you to read the third link in my first answer a second time, and maybe use a few minutes to look at the photos, where the position in front of the sprayhood is well illustrated. The lines passing through the sprayhood are also shown, and also the clumsy way that Hanse has chosen to handle the lines. If you choose to read the other links a bit more carefully next time, you will see, that the system which Hanse has used since 2009/10 is more intelligently designed.

I am not a fan of having the mainsheet on the coachroof sinse the loads on the sheet and the bending of the boom are extreme!

If you don't see a choice than I would go for the Jeanneau version with a Dyneema triangle. You need to reinforce the vang to control the leach but than you reduce the sheet load with "just" moving the boom in and out.

In a topic in one the first of my links Iemand also has remarks about the boom bending. He is correct, that the forces acting 2 meters from the mast are the double of the forces at 5,0 meters. (force x arm). As I have told before, the Harken traveller in front of the sprayhood in my Hanse had very tiny schackles, which bended when the wind was rough. At first I changed to sturdier schackles, but I did not like the handling of the lines from the traveller. The ropes in the froglegs more often than not came loose, so in the end I changed to the system which Hanse uses today. (As shown in the links in my first post).
For cruising, this new system is superior, and on my boat Hanse has put a solid Sparcraft boom which can deal with the forces of my 52.2 m2 main sail. I do not recall stories of broken booms in this forum, and Hanse has sold a lot of boats in the last 15 years.
Before stating anything too categorically, I (and everybody else)should check the search function, and lo and behold, there are complaints about some Seldn booms. If you are interested, read:

P.S. On some boats the mainsail is fastened to the boom in a milling, thereby distributing the force more equally in the lenght of the boom. On my Hanse, the main is fastened at the mast, and only at the end-point of the boom, thereby putting the main force at the mast and at the end-point of the boom.
