Gennaker sheet block position

[maxfax]

Hi there,

Currently, I am busy with riggging a new assymmetrical spinnaker for my SO 33i. I was planning to attach the sheet blocks to the D-shaped eyes on the pushpit (stern pulpit for some) which I thought placed originally for that purpose.

When I consulted the technical guy in Jeanneau, he didnot recommend me to do so, he suggested installing new padeyes with backing plates on the deck.

I am a little confused because on Jeanneau catalogue, you can see the pictures of a SO30i flying the kite with the exact setup with block attachments to the pushpit.


What would you do?

Thanks..

Personally, I'd take their advice, or maybe use a "soft shackle" (i.e. rope) to attach to a stern cleat. Pulpits aren't really that strong, and might deform under load.

Hi Maxfax,
Here is my 2C's, firstly have a look at hints and tips there is a 39i with a great setup, Bow roller modification for aysmmetric it's called. I have a SO32 with a Selden bowsprit of which I run an ASO and a Code0, the bowsprit gets you away from the forstay by say 90cm and allows for larger sail, clear air. That said if I had to do it all again I would copy the setup from the 39i and have the ASO on a Top down furler and the Code0 just has to be on a furler, that way you can gybe the ASO on the outside or furl up quickly and un-furl once you have gybed.
Yep a longer and more costly process, long term a better solution I think, mounting a block to the split pulpit as on the 33i sounds like a bending time is to be had.
Anyhow that was my 2C's

Cheers

I have an asymmetric and use the rings on the pushpit! I think it really depends on what kind of sailing you are going to do with though. If you are going to use the chute in heavier airs then there may well be a risk of bending the pushpit, but I use mine in light airs only and have not had a problem so far.

Our SO32 has rings welded to the base of the pushpit. The gennaker blocks are attached to the rings. Although I haven't yet used the gennaker since we own the boat , there is no sign of deformation.

Maxfax,
Looks like I got the wrong end of the story (ha-ha) should read the question a bit better, I do use the rings at the base of the pushpit, no problems at this stage....3 years down the track, may be worth checking the washer on the underside and replace if it's just a silly little washer.
I still like the 39i's bow set-up.

Cheers

Thanks for replies.

I have checked the nuts and washers of pushpit and they looked pretty solid to me. Besides, the forces will apply to the base of the pole, that means the majority of the load will be carried by the bolt itself, instead of the pushpit.

flightdeck,
Thank you for your recommendations. I have also installed a Selden bowsprit, with 970mm protrusion from the bracket which is just inside the specs (1010mm for RM 25). In order to be on the safe side, I have replaced the bottom bolt of the headstay chainplate with the same size eyebolt. Then, I have installed a removable bobstay from isolated steel wire. I can post the pics if you want.

Cheers.

What is the maximum wind strength that you mostly sail with your gennaker? I am planning to use mine upto 15-16 kts.


Best.
