If she lives in Richmond, it might be an idea to find a place on one of the 3 arms of the Fraser River and arrange to pick her up in Richmond, Say Steveston, BC, a small settlement I believe on the middle arm of the Fraser River.
She can leave her car there, close to home, and you can pick her up from the fish
dock and return her easily.
Findinding anchorage in the downtown Vancouver area is difficult if not impossible and with all the marine
traffic and I would be prepared to spend all night up on anchor
watch if you do.
Cheers and good luck, Phil(former Vancouver native)
