Final Division Assignment
06/27/2008, Division C Start is Tuesday 7/15 @ 2:00pm

Now this is more like it! Less than 5 hours of handicap allowance between the the slowest rated and fastest rated should make for fun racing.

Conditions seem to be improving

06/25/2008, 20 days left to get ready!

This weather forecast shows promise that our race will take place with almost normal wind and pressure conditions. It is still forming, but the Pacific High Pressure Ridge is taking shape (roughly under the long yellow oval). The magic routing software would have us sail a southerly route. The red star show us theoretically crossing the 130 degrees West longitude at 29 degrees North latitude. Typically, 130 x 30 is considered a good rule of thumb. 130 x 29 would take Sweet Okole over 220 miles of additional sailing compared to rumbline. Another standard rule of thumb is never to get closer to the Pacific High than the 1020 millibar line. As the yellow labels show, the optimal route (red line) clearly would put us above the 1020 line. I'll be watching how this develops very closely.

Appeal to race in Division C successful
bdk
06/22/2008

Whether it was our appeal to the PCYC (Pacific Cup Yacht Club) to race in Division C or the PCYC determined we were incorrectly put in Division D on their own, the good news is Sweet Okole is in the right division now. We will have nearly boat for boat racing with the 2 J-35s and the Express 37. And all boats in Division C are conventional designs (unlike the sportboats in Division D). It won't be any easier to win in Division C, but it will be a much fairer test of sailing skill.

Other new developments are our start date has been moved up a day to July 15th, time TBD.

And today Pam and Dean met with the Pac Cup Safety Inspector and passed the the Safety Inspection with flying colors.

Division Assignments

Well, here are the assignments for Division "C" and "D". It sure seems like the assignments were a bit arbitrary, at least for Sweet Okole. I think we align better with the boats in Division "C". As it stands now our finish within Division "D" will be feast or famine: light to moderate winds (10 - 15 knots) and we should do well - strong winds (15 - 25 knots) where all the sport boats can plane and we'll have a tough time - if it is really windy (25 +) SO will light up and the sportboats will lose their advantage. But the bottom line is if we are going to win first overall, we'll need to beat all these boats regardless of division assignments.

Would you sail across the ocean with this guy?

Not all pirates are created equal. And Dean Treadway is definitely cut from a special bolt of canvas. He's captained the same ship for over 30 years. Along the way, he has acquired many treasures including winning the 1981 LA to Honolulu Transpac Race. And he didn't even have cannons! OK, maybe one. But seriously, would you voluntarily spend 11 to 12 days at sea with this guy? Actually there are 5 sailors who are planning to do just that: Pam, Alexis, Helmar, Brian, and Bill.

Rhumbline vs Great Circle
G. Galilei
06/13/2008

The great circle on a spherical surface is the path with the smallest curvature, and, hence, an arc is the shortest path between two points on the surface. The distance between any two points on a sphere is known as the great-circle distance. The great-circle route is the shortest path between two points on a sphere; however, if one were to travel along such a route, it would be difficult to manually steer as the heading would constantly be changing (except in the case of due north, south, or along the equator). Thus, Great Circle routes are often broken into a series of shorter Rhumb lines which allow the use of constant headings between waypoints along the Great Circle.

Most nautical charts are based on Mercator Projections and hence my manual charting and plotting will be straight lines aka rhumb lines.

The difference in distance between the rhumb line and great circle routes from the Golden Gate to Kaneohe Bay, Oahu is about 7 miles.
