Self furling jib?

[wildcard]

So I have decided to get a roller. Now the question is what size? 130% 150%? I have no idea.... It's for a 1964 CC 35sailyacht motorsailer.
Any advice out there?

What are you currently using? If that is sufficent, get the same. If not, go larger or smaller depending on how it does work for you and your sailing area.

What do you use for downwind sailing? Some kind of Spi? If not, then the poled out genoa is a reason for 150%. But watch out for sheeting angles with such a big sail. For going to windward, it's hardly worth having more than 110%. Unfortunately, furling 150% down to 110% is nowhere near as efficient as having 110% as the full sail, because the best form is never obtained rolled.

I have a C&C 35 Landfall on the Chesapeake Bay, and recently bought a new 140% roller furling genoa. My thinking is that the 140 will be a little more powerful than a 130, but it'll be easier to handle singlehanded than a 150 or 155. If I need to furl it heavily for a storm, it'll keep a little better shape than would a 155.

In the spring, when the winds are generally strong, I'll fly my 100% jib, which has a good shape when fully deployed, and keeps a good shape if I have to furl it a substantial amount in strong winds. When the winds lighten for midsummer, I'll fly the 140% genoa. It'll keep the boat moving as long as there's a little wind. If the wind becomes so light that the 140 isn't enough to keep it moving, I'll use a 3/4 oz. cruising chute, with a chute scoop to help me singlehand it. When the wind becomes so light that the 140 isn't enough, I don't think the 155 will be that much better. At that point, I think the boat will move much better by changing to the cruising chute. The combination of the 100, 140 and cruising chute should provide pretty good performance over a wide range of conditions.

By the way, I'm looking for a good used cruising chute with about a 43.5' luff, and a chute scoop, if anyone has one for sale.

Wildcard/all,

I have a similar interest (will be replacing the existing genoa). I do not want to hi-jack your thread so I'll ask this one question and will be looking at the answers. but just to build on your question to better understand the issues on which to make a decision:

One essentially chooses a sailsize for roller furling based on where you will sail and which conditions will prevail. Ideally you want to have the genoa fully unfurled as much as possible- because it will be at its most efficient. Is this correct? If I understood this correctly, then what other conditions would be considered in choosing a 110% over a 130% or a 150% (other than wind velocity)?

[camaraderie]

Other than prevailing typical wind velocity the only other thing you need to consider is the availability of a proper sheeting angle for the size you desire. This can almost always be achieved through various hardware additions (additional track, turning blocks, snatch blocks etc.) but needs to be thought out in advance of purchase. One might also argue that conditions which would support a 150 would be better met by a drifter and a smaller genny.

The boat is in Hawaii with trades 10-15 most of the time. My 100% works well but I think I want a little more on the roller? Like a 110 or 130 or even a 150???? Im just not sure of what I need.

If you are currently satisfied with the performance of the 100% jib, then probably go with the same again. There is a lot to be said for the ease of tacking a non overlapping headsail, especially if sailing shorthanded most of the time.

A new sail the same size is going to improve performance anyway, and if you are indeed satisfied at the present time then you're most likely going to want to reduce sail now and then rather than go for more. Using a 100% sail also means less time sailing with an inefficient partially-furled sail.

wildcard - You should be able to get your sailmaker to modify your existing jib to fit the furler. Then you can see what difference the new luff makes. I would go for a little more area to increase reaching perfromance a little.

I have a load of jibs on the boat. 50, 100, 130, 150, 180% Ive only played with the 100% I have no idea if Im satisfied with it as Ive only sailed it half a dozen times. The wife is the one hot for this. I guess she does not like the current method of stowing the jib which involves me yellling a lot so she says. LOL
Thanks for the advice, please keep it coming.
