Title: Should I keep the jib up when flying the spinnaker ???
Post by: Jeff Coe on July 02, 2009, 10:56:01 PM
I'm sailing PHRF with no other Viper's to learn from.  We're having trouble flying the spinnaker well in light air, and this may be because we've been leaving the jib up.

What is best practice on this?  Jib up or down?  Does it depend on wind strength?

Thanks

In the really light stuff (<5k) it can help to drop the jib.  Otherwise leave it up--just be sure not to overtrim it.  Downwind in light air is tough in PHRF--the displacement boats with symmetrical chutes sail straight for the mark while the Viper has to sail tight angles back & forth across the course.

If you spend a lot of time in the super light stuff (PHRF) you might want to think about a new headstay/jib with harken HSB463 small boat furler. Install a zipper luff on the jib, build a headstay with the harken on it and viola, you're done. In light winds the jib definitely interferes with the kite. This could be a real boon for light air PHRF racers.

Don't forget about your six second credit in PHRF for the roller.
We tend to be dropping the jib more often than other boats in under ten knots  of breeze and everyone seems to drop in under six knots of breeze

6 seconds? Is this for REAL? It's a CREDIT?

Damn, I gotta ask the SFBAY PHRF office if I can do this. Take me from 96 to 102...hey, everything helps :-))

Thanks to Timbo, I took the jib down this past weekend-- in light air.  The difference in the area of ease of trim and jibing was incredible. 

Another good thing about taking the jib down is that it gives all aboard a very clear view of exactly what the Asail does in jibes-- it folds and rolls on itself much higher up than I thought it did.

Ok.  Is it class legal to do a furling jib?

No, a furling jib is not class legal.  But it would be easy enough to swap back and forth as desired.

it's not class legal but it is phrf legal. It's a very simple change for the forestay but you would need two different jibs. One furling jib with vertical battens and then the class legal jib.

No credit locally in SF Bay...only if you race non-spinnaker.

Oh well. I sail on with a 96 PHRF >:-/

I think a below deck furling Viper would rock though.

BoomSlang, if it makes you feel any better, my PHRF-LO rating is 90.  If I put a motor on the back, I get 12 seconds back.  I'm looking at trolling motors.

Torqeedo. Without the Battery they only weigh 12 lbs. Powers the boat VERY well. You can stow the battery in a big ziplock in the wet lockers =P

I agree, I use mine for a half hour to the course and a half hour back on full when there isn't any wind and I am fine...

The Torqeedo was my first choice until I looked at the price.  We have 3 boats to outfit.  The Minkotas plus sealed batteries are about a 1/3 of the price.

I found a motor in model plane store. Gasoline engine + prop weighs under 2 lbs. Not inclined to spend the money just to spite the PHRF measurement, but it probably weighs the same percentage wise as a J24 outboard.
