Get out and enjoy the weekend! Beautiful day today and it looks like it will hold for the weekend. Perhaps the most interesting feature this week is Hurricane Ophelia as it continues to build with some models showing the British Isles taking a direct hit.
Then there’s the tornado outside of Portland turning over some small planes. The great thing about the weather is that it’s never boring.
Today’s chart shows a setup most Vic-Maui, Pacific Cup, and TransPac sailors dream about; a nice and round 1041 MB high-pressure system with almost perfect spacing in the isobars. The only problem is that weak low-pressure system sitting over the Pacific Northwest. This will result in some atmospheric instability and generally light conditions over the Salish Sea.
For PSSC this will mean a pretty nice southerly over the Shilshole area and about 8-15 knots until late in the afternoon when the breeze will start to drop and shift more to the southeast. Sunday the breeze will fill in from the north at about 8-10 knots and should hold for the day. All in all, pretty perfect conditions for a regatta.
The tides will cooperate as well which will make the racing very interesting. These are the tidal currents at West Point.

With the southerly and a flood tide for the start of racing on Saturday you can expect a southeasterly shift along the shore north of Meadow Point and along the breakwater off of Shilshole. Even with a flood tide, there will still be an advantage to going left off the start line and minimizing the number of tacks to the weather mark. Chances are it will also pay to do a starboard pole set at the weather mark and hold that until you start to get lifted as you sail north. After the bottom mark, the direction you go will depend on how far to the west the mark is, where your competition goes and how far the wind is to south or south-west. If the mark is way to the west than you may not be able to go far enough to the east to get back into the south-easterly. If this is the case then it’s back to basic’s, stay between your competition and the finish. On the run north be sure to have someone check the flags on the committee boat and see which end of the line is favored and if one side of the course is favored.
The northerly on Sunday will make things even trickier as there may still be a slight north-easterly component in the morning. If the sky is clear over the downtown area and it can heat up sooner, this will bring the wind around to northwest sooner. Again, keep your head out of the boat and watch which way the smart guys are going.
Good luck and have a great weekend.
