Interesting. I have only had occasion to use my storm jib once on the M17. Winds were 25-30 mph with gusts up to 40. I was very glad I had it. The sail is the recommended size for a Catalina 22: 12’ x 6’ x 9’ Making it 26sq ft, 65% of LP but only 35% of the foretriangle. It turns out that the working staysail on my VN23 has almost exactly the same dimensions as the 110 on my M17. I could have saved some money there since I can only sail one boat at a time. But I also have a heavy weather staysail for Chiquita that is 14’ x 6’ x 11.5’ , 35 sq ft and 76% of LP but only 48% of the actual foretriangle of the M17. I will have to try that on Monita in heavy weather before I commit to anything additional. If I go the roller furling route it might be best to sell Monita’s 110, 135, and 150 in order to buy a purpose made RF 150. I could put a luff tape on either the storm jib or on Chiquita’s heavy weather staysail and change sails when conditions warrant. I would not roller reef the heavy weather sail, it would only be flown full size, such as it is. Henry On Fri, Jan 25, 2019 at 3:27 PM Dave Scobie <scoobscobie@gmail.com> wrote:

'storm' is really small. for the Mboats & Sages it is better in a blow, meaning 25 knots or so, to use a heavy weather jib at about 85%. a storm jib is much smaller. a 110% rolled to about 85% is still a well shaped sail (foam luff and well designed by the loft).
the issue in making a small sail is moving the center of effort forward and having lee helm. this is where a solent stay sail can assist.
converting sails really doesn't work as the cut for a roller furled sail is different than a hang-on ... also adding a foam luff ... and also luff, assuming the current sail is full hoist, will be many inches to long in the furler's extrusion length (meaning you either cut off the sail's head or foot and change the shape (for the worse).
the toggle will add length to the forestay. for example using a 1/4" Eye Jaw Toggle,

This can be taken up by the turnbuckle if it isn't already turned down more than about 1/3 to 1/2 its available length. adding a little rake to the mast likely wouldn't hurt if you can take up the tension with the backstay turnbuckle.

Thanks! That’s what I wanted to know. There is no need, then, for a Solent stay arrangement if the Genoa can be swapped out for a smaller sail fairly easily. Can the 110 be furled down to storm jib size or would it be better to convert the luff of my existing storm jib? I would try doing the 110 and storm jib conversions myself with a Sailrite kit and possibly the 150 while I save for a “real” RF 150.
Also, does adding a toggle require shortening the forestay to keep the same overall length?

Henry.
The Snapfurl is more than strong enough for a heavy weather jib. The weak link is the forestay swage fitting that is already on the boat.
Be sure to install a toggle at the upper end of the forestay (so there is one at both ends). I repaired a M17 that this wasn't done ... owner lucky he didn't loose the mast.
Loading the jib on a Snapfurl is much easier than the CDI. You can never correctly tension the luff on a CDI.
Many headsails is just a matter of money! ;-)

Exactly! It would be simpler, though, if the rolled up jib was removed and replaced with the storm jib. I'm trying to determine if it is practical to do so. Not easy with the CDI, not sure about the Snapfurl. If doable I would add a luff tape to my storm jib. If not I will use a Solent stay.
Dave, you seem to have experience with the Snapfurl. What do you think?
