It’s the first week of March so it must be time for CYC’s Center Sound Series, one of our favorites. True, it’s not like the days of having 500 boats out there but with around 80 there will still be some great racing. Earlier this week it was looking a bit grim as in Crossfire taking 12 hours to complete the course. As they do in the Pacific Northwest, things change. Now it appears things might not be so bad. Some forecasts are calling for 15-18 from the NNW while others are saying 5-10 from the NNW. We’ll just see who shows up.
One thing we do know is that the tides will for sure be in play however even they won’t be too bad. There will be varying amounts of ebb from 0630 until slack at noon. I’ve included a chart to explain this oddity.
Tidal Current at West Point
0630 Ebb .32 knts
0912 Ebb .10 knts
1054 Ebb .15 knts
1206 Slack
1448 Flood .93 knts
1718 Slack
1900 Ebb .46 the knts
Looking at the charts, you’ll see a 996 MB low off the Oregon coast which will remain nearly stationary as it slowly weakens becoming a 1006MB by tomorrow morning. This low will dissipate late Sunday. Meanwhile, high pressure (1040MB) over British Columbia will drift slowly SSE resulting in weak offshore flow over the area through Saturday. This flow will become nearly flat on Sunday. How fast this moves our way will determine just how much wind we’ll have over the course. The best way to check this is to note barometric pressure at Bellingham(currently 1006.7), Portland(1006.6), and Astoria (1004.4). Then check the gradient tomorrow morning on VHF when you get to the boat and see how much this has changed. Generally speaking, if you take the difference in MB’s and between Bellingham and Portland and multiply times 5 that will give you the windspeed in knots. This is more accurate when the pressure is higher in the south. When it’s higher in the north it is less so.
Assuming it’s a northerly, the key to success tomorrow will be getting a clean start off the line and then watch your COG and SOG to make sure you are in the strongest ebb. You’ll hold starboard off the line staying in clear air, there should be slightly more wind in the center Sound. You’ll want to tack when you can lay the mark however you may want to tack early as there may be a lift on port as you work up the Sound. Tacking early will also give you time once you tack back to starboard to get the pole and gear setup which ideally you would have done at the dock. It should be a starboard tack set.
You’ll want to hold the starboard tack on the run. As you get over near the Bainbridge shore you’ll watch the true wind speed, when it starts to drop, that’s the time to gybe. You are better off to come into the Rock on starboard, just know where all the rocks are! You’ll have to do the drop and gybe immediately, then get set-up to drop the daffodils for Kelly.
On the beat back to West Point, it will be hold port tack from the Rock to Four Mile Rock under Magnolia. The flood may have started however there may still be some ebb along the shore from Four Mile to West Point, just don’t get into too close. At least in the flood, you shouldn’t be on for long.
From West Point to the finish, you’ll want to hold starboard off of West Point until you can tack and make the entrance buoys. Really pay attention to where the finish line is and don’t tack too many times but really maintain a clear air lane to the finish.
Good luck, be safe and have a great time.
Ed. Note: Thanks again, Bruce, for the insights. There are going to be some interesting tales to tell, from this, and all the other, Center Sound races. I’ll be looking for details from every part of the fleet – if you send me your insights I’ll work them into the race wrap. I’ll also be looking for video to include on the Wet Wednesday post. I’m not looking for the crew to drop the halyard to get some footage, but if you have some video, share it with me and I’ll share it with the sailish.com readers (even those not on Facebook….) Have a great time tomorrow!

He earned a Bachelor’s of Science from the University of Washington in Biological Oceanography and learned meteorology “to keep from getting kicked around on the race course.” Bruce spent nearly two decades as Associate Publisher for Northwest Yachting Magazine, retiring in mid-2015, and was the chairman of the board of trustees for the Northwest Marine Trade Association in 2014.
