Has anyone considered/accomplished extending the bowspit?  If so, how much longer?  Any reinforcements? Do you think the bowsprit holder could withstand a longer bowsprit?  I would like to make one up to triple the size of the factory bowsprit.

I bended my original length bowsprit last summer.
When sailing genakker in about 20 knots of wind.

Maybe a safer solution.

Lats year, using a code zero in 15 knots wind this happened :
So I got another bow sprit under warranty and fixed it that way :
Now the problem seems to be definitely solved.

Wow, never thougt that this pipe could bend under a gennaker this way, as the material in my case is pretty thick. But i like your solution to make it stronger. thanks for sharing.
 
Just sailed last weekend in 12 kn of wind (half wind) with our 106sqm Gennaker. very fast, but now i will be very careful.....

When in light wind I use also a symetrical spinnaker. This is a second hand spi of IMX38, 120m2. I got it up until 22-25 knots of real wind, woww!!! Speed constantly between 9 & 12 knots, but no place for a steering mistake...After half an hour of this game I was quite tired and we reasonnably put it down.
 
On the other hand the efforts with a Code 0 are much more important than with a gennaker as we can go up to 60° of real wind in 12 knots (after that level we are overpowered) and we tight the halyard as much as possible.

It's interesting that the sprit bent but there appears to be no effect on the base into which the sprit fits.  This tells me that the base can carry a longer sprit provided the sprit is made heavily enough.

Hi Meaban,
I just got my Code 0 and I am very enthusiastic : about 80% of the true wind speed at 70/100°.
The North Sails dealer here advised me not to carry this sail above 10-12 knots. I used it up to 12 knots and it did pretty well. I pulled it down in stronger wind, but with regrets !
Do you think you could be beyond the limit for this bowsprit ?

I believe that downwind there is little risks of damaging the bowsprit, and we can keep the code zero up to 25 knots at 140° of real wind.

As you said we are overpowered closed haul over 12 knots of real wind. In such situation the bowsprit risks to bend.

IMHO the code zero halyard needs to be tighten very much over 10 knots of real wind, and this is adding even more pressure on the bow sprit.

The reinforcement I did is very quick to do, and now I feel much more safe.

Meaban,

How did you connect the reinforcment on the bow? just some screws in it?

Regards,
Ron

There is an aluminium reinforcement inside the hull at the bow, and I have added also an inox counter plate inside.

hi tell me more about the code zero, is it on a furler?do you hoist it on a spinnaker halyard? when done do you just drop in a bag with the furler attached? thanks david h430e

Hi

The code Zero is on a Karver KF2 furler. Very easy to furl.

At first we were using the spinnaker halyard but the code zero and jib furlers were touching each other at top end. Now we have a specif block fixed in the mast up to the jib head point (Orange Halyard).

Ooops!!! you can see at least 2 mistakes : the second spinnaker halyard is at the wrong place and also the headsail halyard point is not properly fixed...
Hopefully this picture helped me to correct those 2 points before any damage occurs.

Meaban,
Perhaps I didn't understand your statement at the bottom of your picture but I thought the upper "loop" was for the spinnaker/Code Zero halyard and the 2 lower "loops" for the jib/genoa.  Right?

In fact there are 2 spinnaker halyards, and originally they go through the 2 rings you see over the self tacker head.

So now I only use the orange one as spi/code zero halyard, and the other one is used for the spi pole (not very practical indeed).

Hi,
this our 375 with the bowsprit system of the 370, which we adapted and reinforced.

Looks great.  How does it attach to the underside of the bow extension?  Also, how do you like your Furlex.  My Hanse came with a Facnor and I have never been happy with it.  Too hard to furl.  Requires use of winch always.

The attachment to the underside of bow extension is welded. The Furlex works OK but is also rather hard to furl, but we don't need the winch. The Facnor 2500 furler for the code 0 works really great.
