Division Assignments
Sofa King Random
06/20/2008

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.

Go North ???

06/12/2008

This is a crazy weather pattern. Would we really have the the gumption to go north of the rhumbline / great circle route? The optimal route assumes that weather conditions would evolve over the 12.5 days it predicts it would take Sweet Okole to finish. With luck weather will settle into more typical summer patterns in the next few weeks.

What is the difference between rhumbline and great circle route? Answer in my next blog :-)

If we were out on the pond today

Periodically, I will put up these computer generated forecast maps (aka Grib files) up on the blog. If we had started today, we'd be flying offshore with 25-30 knots of breeze coming from the NNW. The black curving line is the great circle path and the red line is the optimal course according to our "Expedition" routing software

Sailing Sweet Okole to Alameda
bdk
06/01/2008

This afternoon Dean, Pam, and I sailed SO from Richmond to Alameda (without the benefit of the engine working as the water pump was accidentally fried the week before.) The purpose for the sail was to deliver SO to Svendsen's Boatyard where starting Monday, new state-of-the-art instrumentation will be installed.

We made good time aided by a waning ebb tide and fresh 15-18 knot breeze. We flew the AP (All Purpose) 125% No.2 jib. Pam went up the mast to mark on the back edge of the sail (aka leach) where the sailmaker will put reinforcements. Pam repeated the process on the mainsail. Even a small amount of the spreaders and sail rubbing together over 12 days can at any point in time, scratch a hole through a sail.

The light running spinnaker (aka "The Contessa") was flown and I took pictures to pass along to the sailmaker. This spinnaker has an oddly shaped top half in which the leading edge literally folds over right before the entire kite collapses.
