- 20180531: Mike Nikolich inspected the jib. There is chafe on the UV cover, needs a sewn repair in each location. Dacron tape does not stick to the UV cover (Sunbrella). Identify what is chafing the UV cover so that the chafe can be eliminated. The head of the jib, which is not protected from UV, has some damage. Not severe at this time. Webbing at head and tack may need replacement. Sail has some life in her yet.

Skip Novak "down south" mainsail design points :
- Full length battens.
- Webbing with rings on both sides of each tack reef cringle so that the tack can be secured on either port or starboard when reefing.
- Webbing handles, large enough to insert the whole hand, sewn into the luff above each tack reef cringle for pulling the sail down to the reef position.
- Very heavy chafe patches on the battens whereever they may touch the rig.
- All seams with four rows of stitching with cover strip over the seam to protect the stitching.
- Blocks sewn to the leech of the sail above each reef cringle with an additional cringle half way down to the next larger reef cringle, so that the reefing line may be lead from the boom, through the cringle, through the reefing block and back to the boom end. As a result, the sail will accordion on the boom, folding at the intermediate leech reef cringle.
- Fourth reef in place of carrying a storm trysail.
- Three roller furling headsails: 140 yankee, 90% jib, and staysail which is cut flat as a true storm jib. No changing head sails in bad weather. Reef early, reef often. Reef when you first consider that it might be necessary. See Skip Novak's Storm Sailing Techniques Part 3: storm sails
Skip Novak "down south" headsail design points :
- Hollow leech sails.
- Conservative cuts.
- High clews.
- Permanently rigged staysail/storm jib.
Daniel Swords on how he sails:
When I purchased my boat it came with a 150% furling genoa. I found that sail was slow and difficult to tack singlehanded and became overpowered, developing significant weather helm, in winds over about 15 mph. The large sail was also difficult for me to furl in high winds and didn't set well when partially furled.
I am currently using a 110% genoa which I like much better. It is much easier and faster for me to tack and to furl the sail even in high winds at the end of the day and I can also see around and under the sail much better when sailing around other boats.
When the wind gets up to about 18+ mph I put the first reef in my mainsail. My boat balances beautifully with only a very slight weather helm in winds of about 18 to 22 mph with the 110% genoa and one reef in the main.
When the wind gets up to about 22 to 25 mph I put the second reef in my mainsail. With the full 110% genoa and two reefs in my mainsail my boat has a totally neutral helm.
With winds above about 25 mph I furl the jib by about 70% to what I consider to be storm jib size. I find on my sail that furling less than this creates a big belly in the luff of the jib but that belly flattens out and disappears at about 70% furled. My boat sails faster and handles better even with this small jib than with just a double reefed mainsail.
In winds above 28 to 30 mph my boat seems to hove-to well on just a double reefed mainsail and no jib, but I do not get a lot of practice sailing in these higher wind conditions.
One caveat, getting the proper lead on the jib sheets with this size jib is a slight problem. The genoa tracks on the toe rail on my boat do not go far enough forward for this smaller sail. I find the sail trims best on the inside jib tracks with the sheets led inside of the cap shroud but outside of the lower shrouds. This also allows me to point higher than I could with the larger genoa. But it means the jib sheet rubs on the inside of the cap shroud on a close reach and the jib sheet knot on the clew tends to catch on the cap shroud when trimming in from a close reach to close hauled in high winds. I am currently working to resolve this problem but haven't yet found a great solution other than to luff the sail while I trim it inside the cap shroud.
Alberg 30 Fully Battened Mainsail, Luff 30.75, Leech 33.49, Foot 14.25

To Jonathan Bresler,
Thank you for your enquiry regarding the new Alberg 30 Mainsail we
currently have in stock.
This sail was built to standard class dimensions for an Alberg 30 owner
who, after receiving the new sail discovered that his rig had been changed
previously. Thus he had to return the sail so we could build another to his
custom dimensions.
The sail is built in premium Challenge 7.3oz High Modulus dacron. It has a
standard nylon/carbon composite headboard with 4 full battens and 2 reefs.
The battens are evenly spaced and the reef placement is standard, at 12%
and 24% up the luff. It currently has 7/8" external slides on the luff and
loose foot with outhaul strap. The sail includes Cunningham, Alberg 30
insignia and currently has sail #221 installed.
This sail is available for immediate shipping. Shipping cost is $38 to MD.
There is no sales tax outside of Florida.
Thanks again and we look forward to being of service.

Would like to know more about this item. Among the questions that come to
mind are:
* condition
* age
* manufacturer
* material (assume Dacron, but dont know)
* weight of fabric
* headboard material and size
* number of battens
* number of reefs
* position of battens relative to reefs
* type and size of slides
* photos
* cost of shipping to Silver Spring MD, just north of Washington DC
Thank you,
