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,

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,

I cant remember how many mm above, but could be something like 300 mm

I got the exact measurement from Selden. 

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.    

 

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.    

 

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

Thanks in advance

I didn't have the chance to post my final feedback on this thread.

Eventually I decided to have a try with the standard mast configuration (i.e. without moving the gennaker halyard higher on the mast) and it proved to work perfectly well. I added a bobstay, though (as advised by the yard).

Here it is in all its beauty :

 

Is your bobstay also attached like on the pictures ?

I have a 2014 model; I think the yard introduced the rings only recently.

Here is how they fixed the bobstay:

would love to pick this up:

I have the standard Elvstroen furlstroem on my 345 since 2014. Very pleased with it, as we are sailing mostly in light wind conditions ( bft 1-3 ). However I noted that my standard bowsprit was slightly bending upward when you pulled the halyard tight with the electro winch. I have therefore added a bobstay consisting of a threaded eye replacing the lower screw of the stainless bow attachment, a stainless spanner and an eye below the bowsprit. I have the feeling that I can point higher with this attachment, clearly this set up avoids the flex of the "bowsprit".

thanks a lot for your answers. They are very helpful indeed - and we will make sure that we reinforce the bobstay. Also my Hanse dealer reassured me that there is no need to change the mast configuration with the Z-spar mast, but it is recommended to get a Harken (Fallabweiser in German, not sure whether that's translated correctly ;-)).   

Good to hear that the Furlström goes in light winds, because that's what we want to have it for and other (cheaper) options are mainly made of fabrics that have double the weight per sqm...
