As I mentioned, I'm going to be in the market for new sails one of these days when I finish all my current projects. One thing that concerns me is the boat's better pointing ability when sheeted inside the shrouds. Can you go larger than 100% jib and still sheet inside or is 100% pretty much the maximum for that? The stock Genoa is so baggy when furled that you don't get all that much benefit I've noticed by just rolling it up to 100%. I'm sure those luff pads help, but I've heard that even with that, you still can't match the shape of a jib when furled down to 100.

For sheeting inside the shrouds, 100% is pretty much the limit. The leech on anything bigger would hit the lower shroud.

Luff pads do a very good job of removing the draft from a genoa. It might cost a degree or two of pointing, but that's all.

However, if the 150% genoa is too powerful for the winds where you sail, I believe one could design a 125% (approximate size because I don't have exact boat measurements) that would sheet outside the shrouds just like the 150% does. The 125% wouldn't point as close as the jib though.

It might be possible that you could use the 125% to advantage when you furl it about an 88% if you put sheet leads at the back of the cabin top. It would have a decent shape for pointing when furled. However reaching wouldn't work well with it furled to 88%, because the sheets would hit the shrouds and put a hook in the clew.

The 125% might work ok, without hooking the clew, if you furled it up to about a 40% and ran the sheets to the existing cabin top genoa tracks next to the mast. I haven't spent a lot of time figuring out if a 125% will work furl to 40%, because I'd have to construct a CAD drawing in 3D, and that' waaaay too time con$$$uming to do. There's no money in it for me to do that.

From a sailmaker's perspective, the biggest limitation for reefing headsails is the location of the genoa tracks on the Mac 26X & M's. As you reef the headsail, you need to move the genoa car forward to the right place to get proper tension on both the leech and the foot. Between the existence of that lower shroud and the shortness and location of the genoa tracks on the Mac26's X and M's isn't set up to take full advantage of furling headsails.

If you gonna buy a new headsail get the UV stripe and the new sail. If no new sail get the sock, BWY sells one, but after reading up on Judy's UV stripe…and ordering one…I think thats the way to go. In the past I was looking at a sewn in cover but it was sunbrella cloth on a OEM sail, which was not recommended by the dealer as I'm sure Judy will tell you, but the UV darcon stripe, now that's pretty cool especially with an expected life span of 12+ years down south! Up here I can probably expect it to last 2-3 times that. :D

BOAT... I purchased mine here: ...It is a pain in the A$$ after a hot sweaty day of sailing ....go for the built in UV cover on the sail

Judy B made me a new 100% jib, so I will be done with the Genoa sock...review to follow in 4 months...(She is a pleasure to deal with and would recommend her as your first choice for a sail replacement!)

Okay, IF I need a sail I will go to Judy, but I have this brand new genoa sitting here. I just got it all nicely rolled up on the furler yesterday and now everyone says I need to put a sock in it! (Uh, I mean 'on it').

So the sock goes up a halyard. WHAT HALYARD?? I do not have a halyard on my boat except for the one that is on the furler (can't use that because it spins around and around!) and the only other halyard I have is for the MAIN!

So why do these people keep telling me to pull the sock up the furled genoa with the HALYARD?? (What halyard?)

Ah, you had the same people rig your boat.

You may want to do as I did and attach a block to the mast above where the foresail attaches so you can pull your sock up.

Like I say, I've been using my stock 150% here in San Diego, always exposed to UV, for over two years and have had zero problems with it. I know UV is degrading it but we're talking about a five year course, not one year or six months, and frankly, these stock Doyles were never going to last a decade anyway.

I wasn't that happy with the stock sails when I bought my boat, and just figured I'd use them until they were beat and then replace them with "real" sails. I'm two years down the road, and liking them more all the time as they just continue to work.

If I wind up having gotten five years out of them, I'll be that much money ahead. I am planning on a sail purchase well in advance though, so when I tear one I can just take it off and replace it.

Matt..you might make it to 5 years in SAN but I doubt it. That's heavy UV country. Damage is tough to spot until the sail material fails. The upside of the sock is you only pay for it once and yu dont degrade sailing performance ...snickers from the audience not appreciated.

Why not add the sacrificial UV to your new Genoa?
You can either buy the sunbrella and sew it in yourself (sailrite has a nice video explaining how to do it), or pay a little more than the cost of the sock to a sailmaker and not have to deal with the sock.

Dimitri,
My Headsail is a 105% jib with Dacron cover that is much less weight than a sunbrella cover. I had luff pads with Sunbrella cover on my potter 19 with the 150 genoa and didn't like it.
My new mainsail from Judy B works just great (tho perfer 6 oz instead of the 7 oz I recived, because of handling as a trailer sailer) with the headsail by Hanson (Belive no longer in business).
As you know I sail with a few Mac.X-M's and beating to windward in over 7 knots the Jib can come at least 4-5 degrees closer to the wind compared to the 150.
I often sail in a 8-10 knot wind and can reach to 42 degrees of apparent wind and higher than that in stronger winds.
Having jib sheet lines inboard does make a big diffrence beating to windward and poling out downwind .
Winds below 6 knots a 150 in all points of sailing is better.
This has been talked about many times and just giving my opion.
Any Items aloft including Sails and weight on my MacX is a serious thought in what I want to change.
I trailer Sail so I made up a jib cover from a old sail thats 12 inches wide doubled over and cover the jib at trailering with bungies. This protects my jib even tho it has a dacron builtin when in my back yard in SW Florida.
If you decide on a 150 you can always furl to a 100 and run sheet lines inside.
I also have two full top battens of mainsail, this helps a lot in all points of sailing.
