Planning the Goldilocks Gybe for Vic-Maui, Mountain Retires

Vic-Maui is delivering some of her best to the 2016 fleet, but unfortunately claimed another retirement, the J/109 Mountain (with rudder bearing issues).

Winds are in the 20s supported by a strong high pressure system. The boats are pointed at Hawaii making great speeds. While it’s great for the speeds and crews, if there’s a weak piece of equipment anywhere on the boat, there’s a good chance it will fail. So much of these races is determined before ever casting off from the dock.

Mountain was having a great race until her retirement. Standouts still in the race include Raindrop (no surprise here) and Longboard (no surprise here, either). Those that kept too far to the west suffered, but now everybody seems on track. Coming up fast are the TP 52s Valkyrie and Kinetic and the SC70 Westerly. With Crossfire headed home, it’s likely to be one of those three that claims the elapsed time victory and very possibly the record.

Eventually they’ll have to pick the time for the big Goldilocks Gybe, according to “Guru” Brad Baker. (The guru moniker was provided by the Vic-Maui organizers, he’s still Brad to me).

Baker posted a weather outlook yesterday, reprinted in part below. Check out swiftsureyachts.com for the rest of the story.

The sleigh ride has begun!

Brad Baker Vic-Maui Analysis #3 – July 16, 2016

First off my heart goes out to Lou and crew aboard Crossfire as they have retired from the race. I don’t know the details as to why beyond what was reported on the website, that they had a couple of gear failures. You can see on the tracker that they are now on starboard tack beating their way back home to Seattle. I hope that all are well on board and wish them a safe trek back.

In the last blog I predicted a fast race, record breaking in fact. That is still very much a possibility, even with the fastest boat out of the mix. The weather models continue to show a high pressure system, which currently is around 1035 mb, to build to 1040 mb and obligingly move west and north for the fleet. This has allowed the competitors to point their boats directly at Hawaii. The wind will shift from a more northerly to a more easterly direction as they loop under this monster high pressure system. The most critical decision they will all have to make is when to gybe from starboard to port. A gybe to soon and they find themselves having to sail lower and slower to Hawaii and maybe find they have to jibe back to starboard on an unfavorable shift. A gybe to late and they will have needlessly sailed extra miles. They need to find the Goldilocks gybe, not to soon, not too late, but just right!

routing for righ now. It's hard to distinguish as the tracks are nearly identicle, but I have run routing for both Raindrop and also for Valkyrie

Honestly though, this pattern really isn’t rocket science, and

it will be fairly easy to find a good place to make the jibe. The wind shift will more or less dictate this. The real premium will be on boat speed and holding it all together. With the high pressure system so massively strong there will be an incredibly large area with enhanced trade wind conditions, literally 1200 miles. This means the boats will be sailing in 20 knots plus for quite some time. To put this in perspective the average tradewind speed is about 14 or 15 knots. The well prepared boats that avoid gear failures, and are able to keep the boat moving flying the spinnaker 24 hours, day and night, will be the ones that excel. By the end of this race there will be plenty of stories of parted halyards, wrapped spinnakers on forestays, blown up spinnakers and probably a few boats that have steering issues.

There will also be stories of surfing at high speeds under a brilliant starlit night, with bio-luminescence sparkling in their wake, all the while listing to Dark Side of the Moon on the stereo. It’s magical out there, life changing. Read on….
