Day 1001 [June 30/11 JST] – The Trades Turn Fickle

Today's Report
June 30/11 0800 JST 

Position: 25°21'N, 147°45'E

Remaining to Yokohama: 823 nm (ETA: ? days)
Remaining to Ogasawara: 354 nm (ETA: 5-6 days)

Those wonderfully steady NE trade winds appear to have largely vanished overnight as DMG dropped to just 66 nm.

That's the least he's gained since he accidentally ventured into semi-doldrums at the beginning of June. Then he saw a few days of less than 20 nm distance made good and even a frustrating day when he lost 2 nm. 

This time, a large high carrying variable winds has moved into the area and chased the Trades away. Judging from ClearPoint Weather, this could last anywhere from a day to several days. Fortunately the current is still moving the direction he wants to go.

He reports the ship's batteries are now almost completely drained. We got a beacon position this morning (90 minutes later than usual) so apparently some juice still remains. If the automatic satellite beacon positions stop, we'll continue to get his twice-daily reports by Iridium satellite phone. Each call is now kept to 2 minutes or less.

He reported that he stopped the boat and drifted 3.5 hours during the night to catch some much-needed shut-eye.

During the 24-hr period NBSDIII moved 66 nm closer to Ogasawara, now 354 nm west. Depending on the disruption of easterly winds caused by the newly arrived high pressure system, the time it will take to reach port in Chichi Jima is at least 5 days at 2.5 – 3.5 kts.

At the time of his call, winds were blowing out of the ENE at just 6 – 8 kts, for a reduced boat speed of 2.5 kts. He jibed to a heading of 220 about 070 JST.
Weather was overcast. Sea swells were 1.5 m.
