Hey Michael,
The onshore wind direction with a slight amount of north in it would work all the water pushed up into the bay by the 30-40 knots down the west shore line towards the point. It sounds like a side shore river set up along the south shore pulling all you guys parallel to the shore and downwind on the lee side
We used to launch off the boat ramp and then pinch hard upwind on the first reach to the south. After a quick tack or snap gybe you pinch hard upwind again towards the ferry.
In two or three tacks your upwind 500 meters off the west facing beach right into the big swell. We spent most of the time sailing along the shelf of the bay that the big swell breaks on about halfway to the ferry terminal North of the boat ramp. The water goes from 120 feet deep to 15 along that edge. There's no current to contend with and big conditions. If something happens you get pushed onshore.
You guys are crazy attempting to ride the point wave on a 4.0 westerly
The thought never even crossed my mind when I used to sail there on a westerly........way too scary! I was never great at pointing upwind and probably would have ended up in White Rock if I tried to launch off the south beach.
The west shore break is still smaller than JWSP at high tide without the logs to contend with. Try the boat launch the next Westerly and stay away from the lee side of the point. The swell breaking on the shelf to the north blows the point out of the water. However, the point is sweet on a SE direction
Here's a link to the tidal flow around Point Roberts. Pages 152-154 on the document show the tidal flow:
