Pegasus Open 50 Raceboat Log: Day 5/6 And The Moon

Pegasus Open 50 Raceboat Log: Day 5/6 And The Moon

July 9, 5:30 PM PST Today we are living within the realm of Squalls. Squalls in the the Northeast sub-tropical Pacific are different. They are small, concentrated and powerful. The rain lasts ~20 minutes under them if you’re stationary. We’re not.

I love squalls in Honolulu: refreshing, cleansing and replenishing for island precious water.

On Pegasus 50, we move fast at more than half of the squall’s speed. My personal interpretation of North East Pacific Squalls is that they are caused by evaporation with subsequent cooling of the rising air and travel with the tradewinds. During their build-up phase, they mostly “suck” air into them as they are highly active building convective systems. The upper limit comes when the ultra moist air reaches adiabatic balance. Therefore, if you are in front of such a building squall, you loose a lot of wind velocity and get a nasty right shift, but if you have one behind you, she “sucks air” that heads you if you are on starboard jibe with a great boost in velocity. The longer you ride that squall the better. Mark caught a short video of one that he was riding to a max speed of 28 knots of wind and 22 knots of boat speed this afternoon . Check it out, passing right behind Pegasus 50. Mark is steering and filming.

Insomniac sailor with a Transpac purpose!

Philippe Kahn founded Borland, invented the Camphone, and decodes human motion. He’s also a fellow outdoorsman, splitting time sailing in Santa Cruz. He’ll share his Transpac 2009 sailing race with us live from the Pegasus Open 50. He and Richard Clarke set the race record for a double handed team in 2008 with a time of 7 days, 15 hours, 17 minutes and 50 seconds, besting all boats in overall time for that year.
