|Sabreman||markdigi - I received our rating in the mail today. It's 144.|

All - FYI. According to Glen at Sabre, the prop is 16" dia x 12"pitch
Thanks to kd3pc for the suggestion to contact Sabre. I can always count on Sailnet for practical suggestions.

Mark - I was kind of hoping that we'd have something like 123, but who knows. Our main is old but full battened - definitely not a racing sail. The jib is 140% and old but Sailcare refurbished.
Your avatar is nice. Great boat.

I'm interested in hearing your final PHRF rating. We ended up with a 141 this year as opposed to a 144 last year and nothing changed on our boat.
Last year I believe they started us with a Mk I base instead of Mk II. I pointed this out in our application this year believing that our handicap would increase based upon this discrepency but it decreased.
We also raced against a couple of Mk II's in the Figawi last weekend. One of them had a higher handicap and didn't have a roller furling main as we do.
We have a two bladed fixed prop, roller fuling main and headsail and no racing sails. Our genny is < 135%. The only way I believe another Mk II could have a higher handicap than us is if they had a 3 bladed fixed prop. I plan on asking for clarification from our "handicaper" so that we're correct and consistent going forward.

All- Thanks. I think that the suggestion about contacting Sabre is one that I will take. Don't know why I didn't think of it. I've called them a number of times over the years and they've been great.
Unfortunately, I can't use the calculators. There are too many variables that I don't know. To be honest, I've never paid much attention to prop size and diameter. Sabre spent the time to spec it out so it's good enough for me. I mostly make sure that the prop is free of knicks and is reconditioned every 10 years or so.

you may want to contact Glenn at Sabre...he can give you an idea and maybe an exact answer.
all the best, and the 38 is a great boat.

|JimsCAL||I would guess the pitch would be between 10 and 12 inches.|

Sabre 38 Prop Pitch
This may sound off the wall, but here goes.
I'm trying to get a PHRF rating for Victoria (the boat, not the wife), and the application form asks for a number of measurements for the fixed prop credit. I was able to estimate the exposure aft of the keel (~8'), the length of the exposed shaft (~26") and the prop size (14", I think). I have no idea as to the answer for the final question - pitch. Without diving under the boat and scraping off a bunch of paint to try and see the pitch stamped on the prop, is there a database of standard prop sizes installed for various manufacturers? Or conversely, with a 14" 2 bladed prop @ 2500 RPM, I do about 6 kts can the pitch be determined from these variables?
Thanks for the help
