After several adventures flying the symmetric spinnaker single handed, I made the decision to install a furler on a retractable sprit. I ordered a Selden 75mm sprit and a Harken Reflex 2 furler.  I used the Selden 90 degree bracket and fastened it to the port side of the double anchor roller, opposite the Rocna anchor.  I had to drill four 3/8"(10mm) holes. I used a 1/8" bit followed by 1/4 and then 3/8. I used one fresh 1/8" titanium bit for each hole. Use a center punch, the bits tend to wander on the hard stainless.

The sprit projects 700mm beyond the bracket, and the base is just aft of the anchor locker when extended. The sprit was overlong, and I had it shortened 480mm by the local repair shop at low cost. I will have to remove it to anchor. The next post will show the furler setup.

Hi Graham,

Is the Reflex 2 furler oke for a symetrical spi? I use a asym. spi and I am looking for a furlersystem. So if this one is oké for a symetrical it should be perfect for a asymetrical.

Have fun.

Frank

I am ordering an asymm for it. That is what it is intended for. I chose Harken on the advice of the sailmaker. I do plan to try the symmmetric spinnaker on it but I have my doubts.

Furler in place for test fit. It spins very freely. Still waiting for rigger to splice endless furling line.


The Harken torque rope has a stainless steel outer layer which makes it VERY resistant to twist.

Ordering new spinnaker. Votes requested on color scheme.

Some possibilities. The boat is dark blue. Red and white are the colors of the Canadian flag:

Graham, my wife and I vote for no. 3

We think it will look beautifull with a darkblue hull 👍

Grahame,
 
The modern trend is only one color, but my choise out of these would be #3.

Thanks for the votes. There are of course many other possible designs, including solid colors. Still deciding.

We ordered design #1 which my wife (who outranks me) liked best.

In the meantime I took delivery of an endless furling line, new Dyneema spinnaker halyard and very long floating sheets. The latter, based on cost, must be woven from platinum thread.

This morning early (before the wind came up) I hooked up the old symmetrical spinnaker to the new furler and hoisted it (unfurled). Once up, I furled it. It took a lot of pulls on the furling line but it went smoothly. A very tight furl above the sheet, looser below. The clew goes up very high as it furls.

The photos show it partly and fully furled. It lowered to the deck easily and I packed it in the bag, bottom first, in a figure 8 pattern. Much easier than repacking a loose spinnaker, and it is much more compact.

More photos when we try it out at sea.

This is Echo, we have a similar continuous line furler. They work really well. This was taken a couple of weeks ago sailing Les Sables d'Olone to Ile de Re.

A photo of the (17 year old) symmetric spinnaker on the new Harken furler. The rigger said it wouldn't work. The sailmaker said it might. It works. Photo taken by Pierre Cote on Delicate Balance.

The new Asymm has arrived and we will try it out within the next few days. It is about 10% bigger than this one.

So far it seems great, very well engineered. Have not tried it in any serious wind yet. Will report more when I have.

Installed and tried the new asymm on Tuesday. Very little wind. It looks good and furls well but we never had more than 3 knots of wind.  I'm planning to try again later today and may get some photos.

Today we had 8-10 knots of wind and tried the spinnaker out properly. We could easily reach up to 60 degrees off the apparent wind, and probably higher if need be. Speeds were in the 6.5 to 7 knot range topping out about 7.5. I started out with the main up but found I had trouble seeing the spinny so dropped it. Didn't see much speed difference.

Dead downwind speed dropped to 5.6 knots, still pretty good. I would say it is at least a bit faster in this wind than the old symmetric. A much better shape for reaching.

Then we furled it which went smoothly. The Harken reflex is a first class piece of gear. Left it up and sailed back a few miles to windward. If it interfered with flow over the jib it wasn't obvious.
