cp 23 jib measurements --

[hockeyfool]

can someone please send me the proper dimensions of a storm jib for a 23' without a bowsprit ?
or the size of the 110 jib ?

Which is for a 115 jib. As far as a storm sail it will really depend upon what you want. I picked up a used storm sail (very heavily built) at the local consignment shop for my 23/3.

Luff is 196", foot is 86", leech is 170" and it works out to about 50 square feet. Compared to a true blue water storm sail this is larger than it should be but feels about the right size for how I want to use it.

I have used it multiple times in higher winds (18+ knots) and really like it. I was out last season with the storm jib up and a double reef in the main in 20+ knots and the boat was extremely comfortable and very easy to control. Other sailboats were being knocked all around with too much sail up.

Another time with just the storm jib up I was doing around 4.5 knots in a small craft advisory and the boat was again easy to control, even able to tack if I backwinded the jib.

Well worth the cost if you are going to be out in higher wind conditions. You could also try a jib off a smaller sailboat but they will be made of lighter cloth and may not hold up to high winds as well.

THanks -greatly appreciated !

I wonder about these numbers.  I am considering a new main for our 23/3 which according to this chart is 114 sq ft.  When I sent out requests for the main the quotes came back for 97 sq ft.  P (luff of 22.8 ) x E (foot of 8.5) divided by 2 = 97 sq ft.  Is there really that much roach on a Com-Pac 23/3 mainsail?  Sure doesn't seem like there is that much.  Curious minds want to know.

[Bob23]

There is not that much roach. If I get a chance, I'll measure mine. I still have the old one from my 23, vintage 1985. I'll meas and get back to you.

I'm wondering this...

if you hank on a lot more sail area from any sails...

Are you going to go faster than hull speed?

I think I hit 6.7 knots going down hill on a surfing wave, I don't think sail area had much to do with it.

I forget my calculated hull speed for now, but I think it was 4.6 knots for a CP-19. That's any CP-19.

The bow sprit is mostly for looks.

I read some where that the Cutty Sark clipper ship generated well over several million pounds of 'push' from her fully canvased rig.
And one other thing, for every 15 pounds of 'push' in the rig only one pound of 'push' makes it to the keel. What ever the heck that means.

"if you hank on a lot more sail area from any sails...

Not on a displacement hull. All greater amounts of sail area will do for you is get you to hull speed quicker in lighter air. In heavier air it will overpower you.

The Sailboat Company tried a 40hp outboard on a Compac 16 and it wouldn't plane.... it was still doing hull speed.

Of course it depends on the boat, some displacement hulls will plane under certain circumstances. I'm sure none of the CP boats will.

[Salty19]

Well, I think you may have won the award for "Bringing the oldest post back to life", H2O Operator!     The prize was going to be a waiver of Bob's 5000 clam new member fee, but I hear he's not waiving this anymore.  Apparently he likes clams quite a bit and wants all 5,000 of them!

[Bob23]

Damn right. But for a limited time only, I'll take 2500 raw oysters in place of the usual 5000 clams. Our operators are standing by...this offer won't last!1
