Thanks all. That answers my question. I'll probably be stopping in Neah Bay, Newport, Crescent City and Eureka. Good fuel and guest docks or anchorage in all those places.
Astoria is about 15 miles or so, 30+ total out of the way for a delivery cruise, but is a fun cruising destination; neat town and a great maritime museum you can spend the better part of the day in. Worth a special trip IMO.
Depending on the Columbia bar conditions....

What is the vessel's safe range and cruising speed? For many vessels Neah Bay to Bodega Bay, or further, is a nice delivery alternative. That way the bar crossings are negated with the weather windows now the issue.
If you want to sight see the bar crossings and weather windows can take a 4 or 5 day trip and double it, or more.
Your calculation should include at least 20% reserve off fuel capacity for that trip. There's nowhere to hide for a lot of the way if you guess wrong, have to run harder, or a bar is impassable. Try to get a very accurate consumption benchmark as you head up and out Puget Sound, run different speeds and fill up every chance you get. Always better to know than assume, if nothing else you get a good night's sleep.
It's mostly a delivery trip. Not sure about fuel and range as we havent actually measured it, but we have a week or so to figure that out. With 250 gallons at 5 per hour, makes 50 hours at 7 knots or 350 mile range. That's what I'm using g for plan I. Purposes at this point. We are planning to leave Olympia on the 14th of October and spend a few days in Anacortes and the San Juans. Leaving from there on the 20th-21st and heading south at Delivery pace with me (professional sailboat captain) one hired crew with thousands of ocean miles on Power and sailboats, and my girlfriend who gets seasick, but is incredibly willing to try hard under bad conditions.
Burn rate probably a good bit lower than 5gph at 7.5kts. Probably more like 3gph, but guessing.
Burn rate in the open ocean is higher than the protected waters of the San Juan islands. Then there are ocean currents and wind.
On this trip, he's going "downhill" with both wind and current. Personally, rather than try to calculate what that would add, range wise, I'd ignore it and to the extent it helped, that goes into padding the reserve allowance.
I somehow didn't pick up on the 250 gallons; "yikes" x2 ! If that is really true, make double sure the tank and fuel are clean, bring plenty of spare primary and secondary filters, and learn how to change them.
Guys....
He has 250 gallons of fuel.
