Bruce’s Briefs 6, 7, & 8 Oct. Foulweather Bluff Race out of Edmonds

Bruce’s Briefs 6, 7, & 8 Oct. Foulweather Bluff Race out of Edmonds

Our very interesting year of weather continues after a spectacularly beautiful week of true Indian Summer conditions. As we know, it simply isn’t going to last however there is really nothing major league bad in the offing. That, however, is the bad news.

As you can see from the charts, we have a cold front that is rapidly approaching the Pacific Northwest and will blow through the area tonight. The baro is dropping and we are already seeing rain off the north coast on the Doppler. The other feature to note is the incredibly strong high-pressure system (1040MB) off the coast. This will drive a strong onshore flow down the Straits after the cold front passes. Unfortunately, this will create a convergence zone over the Race Course area for tomorrow. As is typical for a post-frontal scenario, the isobars will ease over the Upper Sound and lower part of Admiralty Inlet and while it may be cranking in the Straits, 25-30 knots from the West, the westerly won’t get much past the Marrowstone Light. While there will be enough southerly in the Race area to get the race started, it will tend to get lighter from noon on. The key to this race will be to finish early.

Running the polars for Crossfire, they should finish just after 1300 hours in a dying south-southeasterly followed closely by the TP-52’s. The rest of fleet may struggle a bit as the breeze will continue to drop. Other projected times are:

Beneteau First 40.7        1609

J-105                                          1648

Farr 1020                                1719

 

The tides will actually be a help. For Admiralty Inlet off Bush Point.

0712                                          Slack

1018      Max Ebb                 2.74 knots

1342                                          Slack

1612      Max Flood            1.75 knots

1842                                          Slack

 

This will be another race that will drive tacticians and navigators crazy as they struggle to keep their vessels in the best wind. The key here will be to keep your head out of the boat and watch which way the smart people are going. For the most part, on the way up to Scatchet Head, simply aim at the mark and sail your polars.

From Scatchet Head to Foulweather Bluff, you will want to stay in the ebb tide and stay out of Skunk Bay where it can get light in a southerly. With any kind of luck, you’ll get around FWB near slack water. Remember that the flood starts first coming down the west side of the Sound and around Point No Point, so watch your COG and SOG. Again, if you’re beating after the mark, stay out of Skunk Bay, there’s a reason why it’s called that….

From Pt No Pt to the finish, have your barber-haulers and light air sheets rigged and ready and aim for the finish. Given a choice between going due east or down the Sound on the west side, stay to the west. Just don’t overstand the finish and keep yourself between your competition and the finish line.

Remember, all of this presumes a long course. The committee has two other options if it looks like it’s going to be really light.

The rest of the weekend really looks OK with the only really breezy conditions being in the Straits. While we’ll tend to have a southerly over the Sound on Saturday, this will shift to a northerly on Sunday. In other words, Stay in Edmonds, enjoy the post-race activities and the sail home on Sunday.

Take a peek also at the surface chart for 10 October. If you were impressed with the 1040MB High, you’ll love the 1043MB monster that’s projected. It also shows another weak cold front coming over us. None of these will produce much rain however it will be getting cooler in the evenings.

Be Safe and enjoy the weekend.
