Mark Coleman is the man:

He runs 28ft fast boats. It's about a 1 hour run
They have a discount rate for the hotel that is 100 feet from their boat.
Fish ice can be had 2-3 blocks down the road.
Never done it but fish are closer to shore in Oregon.
Here is a list of Oregon Tuna ports:

I have heard Depoe Bay & Newport are good.
I went on a Yellow Fin trip outta San Diego & had the most fun catching them on a knuckle bustser using a method called "fishing the slide":
When one or more troll rods hook-up, the boat will be put into neutral , coast to a stop so that live bait can be used. As soon as a troll rod hooks-up, let a "fish trap lure" slide back to where the troll lures were running & engage the reel. It is an immediate hook-up. You need to be standing at the stern with your fish trap ready to go as the slide only lasts 10-15 seconds. I also enjoyed casting a metal jig (3-4 oz) off the bow while the boat was stopped. You will want a very fast retrieve.
I used 20# spectra. The Tuna were 15-20. You probably need real Tuna gear for 40-50 pounders; probably won't get those up here; Morro Bay in October is the spot for the big one's.
A lot of guys on the forum seem to like catching Tuna; I find it a boring fight - they run like hell, tire-out & then flex their body while you pump them in. Mahi Mahi are much more fun, but that requires a plane trip. Raymond Biaz (boat name is Gold digger)out of Bud & Mary's Marina in the Florida Keys in June-July is the man for that - caught 15 from 15-30lb in about 5 hours. You troll dead bait with a spinning reel with the bail open & your finger holding the line. When the fish hits, release the line, wait 3-4 seconds, then engage. Raymond stops the boat, & while you fight the fish he casts from the bridge & hooks more fish, placing the rod in a rod holder til you are ready for it. On our last stop he hooked 3 fish this way for a total of 4 fish on that stop. When we got back to port we had more fish than the other 4 boats combined.
