The average halibut in the Straits is probably around 20-25 lbs. Every year I hear about or see pictures of fish running from 80 to 150 lbs. You just have to drop your gear in the right place.

Another item you might want to consider getting for your vessel is the Canada DFO Current Atlas for Juan de Fuca Strait. The chart book is a one time purchase - about $30. Then you buy the Washburne Table each year for about $7. The atlas/table will show you the prevailing surface currents in the east end of the Straits from about Low Point to Admiralty Inlet and up through the San Juans past Vancouver and up to Campbell River. I use it more than a tide table. It helps to set up your drifts or decide not to go out because the current is too strong.
