Jibeset most definitely shows phrf ratings on the entry list....but the estimated finish etc must be calculated using PCR. The tracker really sucks....surely having the update times the same and synchronized first ping wouldn't be that hard to accomplish.

Dear WB CHristie,

Calculating and sync-ing the positions could be done with some degraded degree of accuracy using as estimated velocity. A spread sheet could be created. In the spirit of improving our data displays I have attached today's position report. Could you please create an XL spread sheet and associated report that shows synchronized , in time, positions ? We would happily post your results here. Frankly I don't have time to do this.

Better tracking solutions are available. It would increase the entry cost about $400 / boat to use them. If racers are OK with this in the next iteration of the race, or maybe a sponsor, "The WBCHRISTIE Single Handed Trans Pacific Race" has a nice ring, we would certainly consider switching to Yellow Brick. Total sponsor investment, about $10,000 in a normal season.

Ah! its free......ok...point taken and sorry for coming across as an ingrate. What did the yellow brick setup cost? The synchronized ping would cost nothing BTW....and improve the tracker immeasurably. That is out of the developers hands.

It's been the same work for 11 boats as it would have been for 23. We're a little tetchy down here. Looking forward to being in Kauai ... and collecting sailors 24/7 in squalls. That's the fun part. Apology accepted. Of course.
 
Were the skippers even asked? All the trackers have the ability to set intervals....

Regarding Yellow Brick, I recall the club getting an additional $7,200 bill from YB after a SHTP. Not expected and definitely not in the budget!

If every boat used the same device it would be possible to sync up the pings. But they don't, and the skippers had to buy them so it's their call. Look at it as a chance to do some math to extrapolate the necessary positions. Maybe create a spreadsheet to automate the adjustments?

Regarding the ratings, the Fleet Assignments page on Jibeset shows the SHTPR's in the Rating column.

Skip, Pacific Cup uses NorCal PHRF's "Downwind Ratings." That's the same system that when new, shot us in the shorts in the 2011 Spinnaker Cup! Jim A has refined the numbers since then.

Thanks for all the hard work Brian...nice to see a Pelagic on Hula! I have enquired about the cost of the trackers from yellow brick, and will report back.

"Instruments? We didn't have no stinkin' instruments. White, .5 oz, hot-knifed, custom telltales were a better indicator for downwind steering..."
I applaud the above from Skip. The look of new sailboats with a computer screen in front of the helm causes me to wonder if the new skipper didn't get enough time staring at a computer screen at work.

The random position reporting is fine intrigue. Stay tuned for final results after all boats have finished and handicaps corrected.

The interim data shows fascinating comparisons. For example, on one 24 hour period, the two Cal 40 sailboats reported a 24 distance that was about 1 mile different in the daily run of 186 miles (about).

The messages from the skippers give added insight to the challenges.

Go skippers Go!

By the end of the weekend it should be the typical 15 knots DDW for everyone. But the race for FTF and maybe overall is pretty much over.

SDK, I watch cartoons on mine.
 
I always figured that the trackers were primarily for safety. That they provide a way for the folks at home to watch the race progress and calculate within a mile or two exactly who was ahead and who wasn't, was secondary icing on the cake.

I tried. This is what I got. Right column is estimated corrected time in seconds. In case there is sponsorship, would I be able to have "Leaderboard brought to you by todd22123?" I do not know how to upload the spreadsheet so others can check the work.

Did any of the fleet experience full moon last night? Moon rise at the cliff in front of CBC was spectacular just after dark. The "Strawberry" moon was peachy with the lights of Monterey and Pacific Grove clearly visible 22 miles across Monterey Bay. Rare to have such clear viz this time of year, what with the marine layer, fire smoke, and dry conditions with trapped particles in the atmosphere.

As we watched, Synbad pointed out Venus low in the western sky and told how on a recent delivery from Tahiti to Hono, she mistook Venus rising for an approaching ship, and spent some effort trying to radio Venus on the VHF. Marilou, Syn's cousin visiting CBC from Essex Corinthian Yacht Club in CT, correctly answered the trivia about the submarine TURTLE on display at Essex Maritime Museum and the War of 1812 when TURTLE, with her one man crew, successfully attached explosives to the British Naval blockade. As well, Douglas, intrepid sailor from Avalon, Catalina, told us stories of Coast Guard activities he had been involved with during his service.

It was time to break out Marianne's Macapuno icecream and organic blueberries when we returned to CBC from our full moon cliff walk. Rreveur, ship's dog, was exhausted by the human goings on and resumed curled position in her comfy bed on the deck. All in all, a most pleasant reunion with old friends we've not visited with in a long time. Synthia will next be seen at Hanalei Bay, piloting the SEA SQUIRREL greeting craft to meet SHTP arrivees at all times, day or night.

What did the 2021 SHTP racers most want to be greeted with upon the finish? A Mai Tai with ice cubes and a paper umbrella? No. An iced cold beer? Neg. Jackie's pineapple bundt cake? No.

What the 2021 SHTP racers most wanted at their finish was......... their hard earned SSS Singlehanded Transpac belt buckle. How Synbad will the join the belt buckle with a welcoming lei is a story for her to tell.

As the General, Ken Roper, once remarked, "That's one expensive belt buckle!"

I am ahead of you . Yellow Brick sends me a quote every year for tracker use. They have the added issue of having to get a commit on quantity well in advance. Had we done this year, with 1/2 the folks dropping out we would have spent nearly $800 / boat on trackers.

Click to expand...

You can set intervals - see my post about having a max interval period of four hours. Intervals doesn't solve the problem. They need to be synchronized and that isn't possible with these systems. The satellites can only handle one tracker at a time, so inherently not synched. Then, lets say the sats could handle 11 trackers in a couple minutes - pretty good right ? Well no really because some trackers won't connect and the message will be delayed. They won't connect because they are badly placed, or the boat is heeled over and the boom/mast/carbon sail is covering the antenna, or as one case we have, the tracker is connected to a poor power source. BTW - YB can have the same issue. We have used YB. They do a better job of syncing and projecting a positions. Of course their mapping is quite cool. All that said, why not take the positions, plot them, note the time diff, and move them forward with your plotting instruments ? Have fun doing it, and post the resulting plot here so we can share the result. Brian
 
Gary, to be clear, you vote for spending an additional $400 on entry correct ? So I wonder if those interested will be ok with about a $1500 entry fee ?
 
Contrary to Stan Honey's slot car lanes, assuming PERPLEXITY's tracker is reporting accurately, John has made an amazing comeback from behind and in the north, to jumping a full slot car lane to the south. He now stands in contention when the breeze begins to fill on Sunday.

Being south of 30 degrees by Sunday looks to pay dividends in days to come. However, it will be difficult to achieve for most. The most experienced routeur in the fleet has apparently followed his Expedition program track, cut the corner, and sailed into high pressure hell. Ouch.

You can bet your boomvang HULA and SEA WISDOM are watching the lack of progress of the "probes" ahead. And hope to pull an "end around" to the south. Both heavy weights will need sufficient breeze to get moving
back into contention. But the trades are coming, 15-20, south of 30 and west of 138.

Patience, Grasshopper.
 
No... I was thinking about sponsoring it..... still thinking...the tracker is a big part of the experience for the families and armchair sailors.
