Hi All, I am adding a furling gennaker to my 345, the elvstrom furlstrom.
My 345 has the selden mast fitted with a gennaker/forstay combination box with the gennaker halyard coming out just above the jib's one.
Is anyone using a furlstrom sail with my same selden mast combi box, i.e. without changing the gennaker halyard position?
 
thank you,

i am picking this up since nobody has replied and perhaps the purpose of my question wasn't so clear.

elvstrom is saying that the hanse 345 mounting the selden mast has the gennaker halyard exit too close to the forestay and the furlstrom will not roll. they are recommending to move the exit of the gennaker halyard at least 300 mm above the forestay to ensure the furlstrom enough room to roll.
is there anyone who has a direct experience to share?
cheers,

Yes, I have to do the same on my H 400 with Selden mast. It was not possible to roll the gennaker with the original halyard. 
I cant remember how many mm above, but could be something like 300 mm
I got the exact measurement from Selden.

Hi
We have had our Hanse 345 along with the Furlstrom since new last year. Firstly it a great way to go. Easy and very safe to use and overcomes the relatively poor downwind performance of a self tacking jib.
The Furlstrom comes with a very nice quality furler at the bottom and swivel at the top. We use the standard spinnaker halyard that came with the rig with no problems at all. I cant think how far it is positioned above the jib halyard but it won't be that far. So I'm not exactly sure why Elvstrom are raising this as a particulalr problem to check. I think it will furl fine. The furler at the foot of the sail will be on the eye on the end of the step so that is taking the angle some way from the jib.
You will need a Bobstay on the step platform as the loads are high especially close on the wind.
By the way I have tried running the sheets on the inside and outside of the jib and would recommend outside (the long way round) works best. Or you can furl/unfurl before /after the gybe.
I hope this helps.

Many thanks for your feedback.
I am going to have a try with the standard configuration before making any change.
Nobody raised the problem about the bobstay though; is that really necessary?
How big is your gennaker?

Thanks again. Cheers.

I think the Bobstay is essential. Inspiration Marine recommended it and I agree. I'm not actually sure the size of my Furlstrom, it's big enough when up! But it will be the standard size Elvstrom recommend for the 345. I think the Bobstay was about £400 but well worth it. Imagine the damage it would do if it rips the step/deck up (which without the support it will probably do sooner or later).
The forces are actually greater at the lower wind speeds because firstly you will be able to sail closer to the wind with the resulting sideway forces and also your boat speed will be further from the wind speed.

By the way we also have the Selden mast. Also somewhere on the forum there is another thread about using the Furlstrom I put some other tips on, it might be worth trying to find it.
Enjoy using it. The season gets under way soonSmile

We have the Z-Spar on our 345. When I talked to the local Elvström loft their statement was pretty clear:
 
a) Furling Gennaker:  You do not need a bobstay, the current bowsprit can take the load
 
b) Furling Code 0:  You must use a bobstay, loads are higher than for a gennie, the bowsprit is too weak.
 
Hope this helps.
BTW: I am very happy with my furlström, especially in the prevailing light winds here in Summer

Quick update: I have been told that the yard is now delivering the 345 with the bobstay and that installing it is highly recommended if you intend to use a Gennaker.

Hi we have a furlstrom on our 415 and haven't had any issues with it all. We have recently bought a Code 0 though and would like to fit a bob stay, does anyone know if there is a fixing plate moulded into the stem to fix the base plate to, or have any recommendations as to how to fix the base plate to the stem.
Thanks in advance
