Spinarker Tack on Bow Roller

[rlojmo]

Has anyone ever used the bow roller for a spinacker tack? Can it
withstand the load?

[dkrun...@wideopenwest.com]

I fly an asymetrical. I bring the tack line through the bow roller and back
to a cleat. I have had no issues, but don't fly the asymetrical if it is over
10 knots (give or take).

There's no reason that the anchor roller shouldn't be more than strong
enough to attach the spinnaker. If it weren't you shouldn't be using it
for the anchor.

I have flown the asym off of my bow anchor roller by attaching a
block to a 1/4" bolt that I put though the upper hole. The bolt has
now deformed from load in no more than 10 knots. In talking with
Beneteau, they caution that the key weakness is in the bow
construction that is not designed to take the force of a flying sail
leveraged off of the end of the bow roller. The loads are much
different from the loads that an anchor imparts. I would advise using
the tack shackle for he jib, attaching a block to it for the asym
downhaul line or welding a ring to the tack fitting for the same
purpose.

I've also considered using the anchor roller as a tack point for my assym.  Guess I'll give it a try next year.  The only difference I can see is that it might be reinforced for a down pull when the anchor is out and not for a force pulling up when used with the Assym.  Dave, Nereus V

I put a block for the down haul of the spinnaker through a hole on the bow.
I have only flown the spinnaker a couple of times, and it seems to work ok.

Thanks Ed, good enough for me.  Dave, Nereus V

What about the spinnaker straps that wrap around the forestay?

I did it on a Pearson 28. When I installed the roller it was for a Bruce
anchor. Everything was properly backing plated and supported. The following
year I ran an asymmetric chute tack line through the bow roller. Worked
great, right up to the time it pulled the whole bow roller up through the
deck! I had not reinforced the roller for a load in the "up" direction. I
would take a very close look at the support for a load going up.

Alternatively one could run a steel wire from the end of the bow roller
to a reinforced attachment at the bow just above the water line? Is
there enough fiberglass there?

[rlojmo]

By the way could someone post a picture of a late model B331 bow roller
from the deck? I ordered the extended bow roller but I seem to still
need a stainless plate that runs back to the anchor locker?

[pegasu...@aol.com]

Ed,

Who from Beneteau said that the bow roller is not designed of handling an asym load?  But is it capable of handling an asym load?

I ahve a 2001 B331 which came with the short bow roller. I changed it
out with a longer one I got from B. It fit with out any changes and
ended in the same place as the one it replaced. I will look for photos
and if i can find one I will forward.
Mine rides low in the bow do you have the same problem?

[rlojmo]

Yes as I said in a seperate post riding low at the bow is a common
problem. Beneteau will not admit it though.

[rlojmo]

[Edward English]

Joe,

The problem is the bow construction, not the roller. The anchor bow roller is typically bolted through and extends out from the bow. With an asym, you impart loads that are up and to the side and forward of the bow by some inches (which multiplies the load by the length of the extension beyond the attachment point of the roller). Further, going through a sea way, water may catch the spin, further adding to the load. Joe Foss at Beneteau said that the boats were not designed to fly asyms from the end of the extended bow roller. On the other hand, if you go from the tack fitting designed to fly your headsail, you should be in good shape. At the Annapolis boat show this year, I talked with the forespar rep and he also said that rigging an asym pole that attaches to the bow, perhaps channeling it out over the bow roller would also be dangerous. He noted that both a 36.7 and 40.7 had tried this and blown their bows because of the loads on the extended poles.

Thanks Ed for the prompt response.  I was planning to fly my asym of the anchor bow roller.

[Neal Lindeman]

Just curious, how much is the extended bow roller?

I have made a small custom pole from ss attached it to the bow rollers body.
I race so I use both symmetric and asymmetric. I use the pole down control
of the symmetric with a block. I attached it to the pole with a shackle and
can control the down haul of the asymmetric from the cockpit. I have used it
for winds up to 15 knots reaching (90-120) without any problem I do not need
the chute for more wind and for higher winds running I use the symmetric
anyway. I include some photos.

I was going to say that this still has the problem previously mention of using the bow roller for something it was not designed for, but on second look I see that your Fore Stay is attached to the front of the roller, so the roller must be mounted differently. What boat is this?

[Taner HALAÇOĞLU]

It is a Jeanneau so45

[Geir Ove Bø]

I do the same on my 411.
And the genakker is 101 m2 and i fly it up to around 20 knots.
So fare so good.

I didn't jump in on this when I saw it because I just recently rejoined the list and do not know the history but just an FYI,

We have an Oceanis 400 with an Asymetrical spinnaker and we use the bow roller for the tack as others have!

 

We've seen absolutely no problems with it all all!

We use ours also. And sometimes the pulpit. The force on the roller bolts by the anchor is actually upwards since it is acting like a lever by hanging out over the stem of the boat. So question is how does force exerted by spinnaker compare to anchor loads?

I run the tack line through a block attached to the folding stainless
padeye on the foredeck back to the bow cleat.
This works for me!

Hi Chris

We have been messing around with this on our 361.
Do you have a picture?
