Weather Updates / 天気予報アップデート

Dream Weaver current location on March 7th at 10:33 a.m. Japan Time

21.7729 N 129.5681 W Course 273° true, Boat speed: 7.8 kts

We spent the morning inspecting the boat and topping off the main fuel tank from reserve cans of fuel we have onboard.   We wanted to take advantage of calm seas and light wind before the forecasted higher wind and seas arrove in the afternoon.  

Since late afternoon, we have been enjoying 15 knot winds and making 7.5 knots of speed in seas of 3-4 feet.   These conditions are expected to continue until we reach Hawaii.

今朝は船の各点検と予備の燃料をメインタンクに補う作業を行いました。午後には風と波が上がって来る予想ですので海が静かなうちに済ませました。

夕方より風速15ノット、船速7.5ノット、3から4フィートの波を楽しんでいます。ハワイ周辺に行くまでこんな感じで進みそうです。

Here are some updates on weather forecast we received.
