Hey All -

I am working on my PHRF application, and trying to determine some things for eventual racing (!) here in Tacoma. I have a pretty much stock boat with full batten main and roller furling jib. I THINK the jib is 135% from the looks of it. Measurements I have taken so far are Luff=42', Foot = 16'7" and the clew cut is low (nearly sweeping the deck).

Does anyone here have a set of Catalina sail dimensions for the 310? Sailrite does, but aside from the main, none are close to the Jib I have. The Genoa measurements on Sailrite's site would SEEM to indicate the jib I have is 135%, but I am not sure.

I have pinged Catalina, but no response yet.

If it is close to the deck it isnt a factory 135

I measured the J dimension today on my foresail.
About 17'-8" .... 17'-10" it was a little windy.

My sail foresail bag has 135 stenciled on it.

I went to the boat Saturday, and measured again. "Decksweeping" is a misstatement, but it is nearly parallel to the lifelines all the way back (not as high cut as the picture on paulj's note). My genoa is 16'8" along the foot with some curve below the tape, and firm tension on the clew. For whatever reason, I measured luff and foot, but NOT the leach.
I am told I will probably have to take the sails off and have them measured during my club "handicapper's" assessment, but I think, based on fuzzy logic (my normal kind), 135 is probably still a good guess for the application.

Now - Anyone out there fit their 310 with a STANDARD spinnaker? Care to share your rigging design? I have some ideas based on other boats I've observed, but would love to hear from a 310 owner or three on their racing experiences.

I know a 310 is not designed for racing, per se, but it's what I have, and PHRF should level [some of] the field. The rest is up to me and my crew.

No spinnaker yet, but here is what I did

I have a spinnaker pole I made as well as a topping lift and a fixed ring. Went with the fixed ring as it looked like I had a wiring track riveted to the front of the mast and the fixed ring straddled the track. I am planning on going with a symmetric spinnaker eventually. Note that no one could tell me what height to put the ring so I put it eye level as I am 5'10' and it is about 5'8" and it is great. I store my pole on the port side using some Forespar stanchion mounts - keeps the deck clear.

Last week strong winds were predicted in Anacortes 30 to 40 knots at the marina.
So I went and checked the boat...My forsail was wraped up tight ,I thought, as I checked it about 4:30 PM and checked the boat lines all looked good.
At 6:15 PM I got a phone call from security that my foresail was loose.
When I arrived 15 minutes later at the boat, the top half of foresail was shreaded.
I checked with local Sail maker and she said sail was not worth repairing........
Any way I checked the sail bag today and it was stenciled 150 not 135.

Looking for a reasonable priced 150 foresail......FX sails?

WOW! Sorry to hear about your misfortune paulj. I just picked up a 155 on eBay yesterday. I also have been cruiising the following sites:

http://www.minneysyachtsurplus.com/
http://usedsails.com/
http://www.baconsails.com/http://www.minneysyachtsurplus.com/

I have come to the conclusion I will sail with the 135, 155, and main next year. See how we do, and how bad we get beat on the downwind legs. The spinnaker proposition is an expensive one, albeit maybe necessary to compete, but I have convinced myself to start out conservative. I also want to understand the Assymetric vs. Symmetric question a little better.

Anyway, might have a few less knockdowns and other embarassing moments in my first season:)

2 things

Second the commiseration about Paul's sail problem. That is a bummer.

On spinnaker sailing, you are basically driving your boat under the sail where it wants to go. We have a boat called Reprisal, a 31' S2?, here on the Potomac skippered by a very experienced and talented skipper (who wins most of the races he get in and placed as I recall in the Annapolis to Newport this year) who had an incident in a race last year where a gust hit his boat, drove the bow underwater and then spun the boat around 180 degrees. He said it was pretty hairy. We also had a race 3 years ago with 28-32 knot winds where one of the spinnaker boats broached with a wind shift and his mast nearly hit the poled out genoa on the guy next to him - saw that one and was pretty amazed no one got hurt or even went swimming. I still like the idea of that parasail spinnaker (or whatever it is called) with the sail 2/3 up, as it is reputed to be easier to manage and handles gusts - just can't handle the price.

Took the boat out last Friday with the new "155" I bought on eBay. Turns out (I am learning as I go, here) the sail is actually a 140%, Yankee cut. That's the bad news. The good news - the sail is in excellent shape, worked well, and cost TOTAL $345. Of course, I had to procure a couple blocks for the aft stanchions to get a good sheet lead, so total cost came in at $410. No regrets.

A couple learnings I'll share.

I have brushed up on my trigonometry and geometry to understand sail sizes and configurations. A great little web tool for sizing triangles (sails...) is here: http://www.mathopenref.com/heronsformula.html

It took me a fair amount of time and effort to run down the information on rigging, sail plans, PHRF handicapping, and racing information. All the research was worthwhile and enjoyable. There is a wealth of information out there, and everyone's purpose will vary, so I won't inundate you with links.

I have come to better understand and appreciate sail geometry, construction, and sail theory. I have slowed down a bit on sail shopping, and have also talked to one sailmaker. I may go ahead and procure a new (true) 155% to have the maximum "non-flying" sail configuration for no-penalty PHRF rating.

Sailrite.com has a database of sail configurations for most production boats, BUT their dimensions do NOT match what I have stock from Catalina. I have not talked to Sailrite to understand THAT.

Catalina did respond to my query on sail plan with a price (no dimensions). Around $2100 for a 155%, which is competitive with the sailmaker I talked to. I am inclined to go with the local sailmaker, if I make the jump to new.

OK - Rambled enough here.

Paulj - Any luck on your replacement sail hunt?
