Furling jib sail

[RKMCCORKLE]

I've got a 1986 Hunter 25.5 with a roller furler. I've blown out an old sail and need to replace it.
I found a used sail for it but I'm wondering if it maybe too small for the boat or furling system. The one that tore was had a 29 luff and the new one is 22

MEASURE APPROX. 20' 8" LEACH x 22' 4" LUFT x 13' FOOT

That will be a sail to small.

You can still use it.... It will not be optimum for your boat.

Size matters if you want to go as fast as the boat is designed to transport you.

But if you just want to mess about and frolic on the water... Why not.

Your Boat Your choice.

 

[Kings Gambit]

Use a pennant to lengthen the luff (functionally) from the head. The smaller sail might be OK in strong wind.

 

[Hollyberry]

Another consideration besides sail area is the luff tape size - it needs to match the foil on your furler...
But really that sail is too small for your boat.
And King is correct, if you do use it add a pennant to avoid halyard wrap...

I sail this boat on an inland lake that's narrow with winds that tend to be flukey and W to East most of the time 8 to 10 knots with gust to 20

Lots of tacking

 

[jssailem]

8-10 knot winds is right in the Go have Fun zone.
is the lake oriented n-s or e-w

This is the boat and lake Wylie

But will this jib suffice with a full main?

What size pendant should I use?

will this jib suffice with a full main?

Please define the term.
What are you desiring to do with the boat?

You could raise a bed sheet and it could suffice with or without a Main.

If you seek to be able to sail / tack up wind with reasonable control and get there without undue delay then no it will not make you happy. Now if you seek to get the sail for free and being on the water is the only focus, then yes it might suffice.

 

[Kings Gambit]

What size pendant should I use?

Looks to be right around 7 ft of total length according to your measurements; 1/4" yacht braid should work.

Well I guess I asked for that, I was thinking maybe with the short tacks I could get by, but it sounds like it might not push thru on those light wind days

I plan to just get out there and sail the boat singlehanded most of the time, I am going to be on a busy lake at times and want control and visibility

Some jib selection info for you to help you decide what can work for you:

The short luff will set the foot of the sail high off the deck. Similar to a Yankee.

What is a Yankee sail? A Yankee sail is a jib with a high-cut clew of about 3' above the boom. A higher-clewed jib is good for reaching and is better in high waves, preventing the waves crash into the jibs foot. Yankee jibs are mostly used on traditional sailboats.

What's that sail for? Generally, I don't know. So I've come up with a system. I'll explain you everything there is to know about sails and rigs in this article.

Hi RKMCCORKLE
Re: The one that tore was had a 29 luff and the new one is 22
This is a much smaller sail in area.
If the luff is 7 feet shorter I am wondering what the other dimensions are.

Anyway this will mean that that sail will be underpowered in light winds. That's that bad news.
The good news is that you have a sail to experiment with and it should do the job in moderate to high winds.
That is when you have the first or second reef in the mainsail.

If you make up two tack strops, you will be able to position the sail up high (7 foot strop) , half way up the foil ( 3 foot strop) and down low to the deck (no strop). Just make the strops out of spare decent double braid if you have any laying around.
Hoist the sail high up for light winds and down low for heavier winds.
In the middle for middle winds . Whatever that means.


Play around and see what works while you save up and buy a full sized genoa.

Should be fun.

You asked...

What size pendant should I use?

Depends on the actual sail you get and how when you go to raise it you find the sail fits.

I would raise the sail to nearly the top, maybe leave 4-6 inches for adjustment, and then measure the distance from the sail luff to the deck fastener.

Stingy Sailor posted an article on pendants.

How to Raise Your Foresail with a Pendant

If you regularly sail in a busy bay with other boaters, personal watercraft, kite boards, SUP boards, kayaks, and the like, it can get downright dangerous. Would you like to see forward under your …

He makes a good observation. You need to secure the foot of the sail and the pendant attachment to the forestay/furler extrusion. When you tighten the sheet you do not want the sail to come away from the forestay.
