OK the J/30s raced this past weekend with 3 other spinnaker classes. Many of us were smoked by the class behind us which started 5 minutes later. After some investigation, many flew .5 oz spinnakers. So my question to the class, should we consider removing the limitation for .75 oz spinnakers? It would make us more completative in PHRF racing with other classes. Thoughts? What is the history regarding why .75 was selected as the standard?

Have you considered they turned on the afterburners to check out your spinnaker logo and see if your crew had been augmented?

Actually David - not enough data to tell anything conclusively here. What did the wind do in the 5 minutes between your start and the other class? What kind of boats and what do they rate?

I think .75 oz is a good compromise for all sorts of wind conditions. I've seen 1/2 oz spinnakers on other boats and wouldn't want to use it in heavy air conditions since we only have one spinnaker for OD racing (plus a backup if the primary sail is damaged). I don' know the history on how 3/4 oz was selected as the standard, but it seems like a good all round weight for what we sail.

When I know it is going to be very light, I take the shackles off the spin sheets (I have luggage tag splices) and loop the sheets through the grommets in the clews.

Here are the facts:

The winds were light and shifty.

Light and shifty on lake Ponch? Last 2 times I was there it was blowing dogs off the chains.

As far as I know you can have a .5 oz in PHRF. You still need a heavier .75 for breezy days so I am not sure what the issue is?

Are you trying to have the .5 without changing the PHRF number?

Ok - now I see what David Bows has written it makes more sense on what you asked. You want to know if the "minimum" weight for the spinnaker specified as 40 grams or .75 oz can be changed to .5 oz. That way, the spinnaker you get measured for OD is any weight .5oz or greater.


As David Bows states, there should be no PHRF hit using a .5 Oz weight spinnaker, so you could fly either .75 or .5 oz in PHRF with the same rating. For OD racing with a single spinnaker, I think .75 is the way we should stay to accommodate the wider wind range.

In my PHRF region, we are required to race in OD configuration, adhering to all class sail restrictions. If we don't we take a 3 second hit.

I've advocated before for being allowed to carry a 1/2 oz and a 3/4 oz. The J-30 is slow in light as we all know, and the 1/2 oz gives a significant speed boost. I know this because our PHRF region used to allow alternate sails from class, and I used a 1/2 oz a lot. I was able to sail significantly deeper and keep the chute filled when the wind dropped off.

My suggestion would be to limit purchases to one spinnaker per year, but allow both 1/2 and 3/4 to be carried. I suspect most serious competitors would carry both, purchasing new every other (alternating) year.

Thanks Steve, that was exactly what I was suggesting. Remove the requirement/specification of .75 but allow the purchase of only one spinnaker a year. Everyone sails across different parts of the country in different types of air. I know it is hard to change based on PHRF benefit, but the best selling point of a J/30 is low cost with two types of racing: PHRF and OD.

I have given up on the logo concept.

Don't you think the PHRF measurer's who now hit you for 3 sec for the being out of compliance of the OD rules by carrying a .5 oz are going to hit the OD rating for 3 sec if the class allows them?

So if you like, go ahead and buy a .5, declare it, and take the PHRF hit.

BTW, I don't know anyone in our fleet that buys a new kite more than once every three years or more.

From what I've observed in our region, the PHRF committee only hits the rating based on a change in the OD rules if the change is very significant-something like allowing removal of the engine, or permitting A-sails. Smaller revisions (allowing hi tech jibs for example) have had no impact.

My thinking is, if you carry two chutes under class rules, you should be able to extend the lifespan of both. This would make more frequent purchases less critical.

Unfortunately for me, my local PHRF fleet seems more on an every other year (and in some cases, every year) sail inventory replacement.

I will say this-sailing in very light conditions with a 1/2 oz is much more fun and less frustrating than with the 3/4-not to mention more competitive in PHRF.

Forgive me - a dumb question. Do we regulate the thickness of the mainsail or headsail?

No weight restriction on headsails, but there is on the main. See extract from class rules below:

5.12.1.3 Sailcloth in the #1, #2 and #3 Genoa is not restricted. This change in approved sailcloth goes into effect no later than October 17, 2005. Individual J30 Class Districts may adopt this change for local events at an earlier date.

5.12.2 Mainsail
5.12.2.1 Minimum cloth weight is 6.25 oz.

On Lake Ontario the J/30 takes a penalty for the # 1 Genoa and the length of the Spinnaker Pole. We have a .5oz kite which is very beneficial when sailing in light air with other PHRF boats.
I would be in favor of changing the minimum weight to .5oz.

HUMOR ALERT!

I am wondering why we designed a set of class rules where you have flexability to use a # 1, #2 or # 3 upwind, but can only use a #3 sail down wind LOL :>)
