Dude,
I have never witnessed any wsb taken from the jetty. Almost all of our fish last night came from the channel. I got picked up once fishing the plastic parallel to the bait barge, but by the end of the night we all had our backs to the bait barge casting into the channel. If you're shorebound, my advice would be to fish the huge flat between the jetty and the base of the pier for halibut. There's a lot of flatties on that flat and you should get quite a few. (I even snagged a batray the other day...felt kinda like a halibut...) For halibut fish the rising tide, preferably afternoon rising. As for the transportation of float tubes, what you can do is keep it un-inflated until you get to where you're gonna fish and get one of these pumps that plug into the lighter and pump it up within 10 minutes. Hey, Paul from bass-n-tubes straps his pontoon boat to the top of his mustang. It can be done. Good Luck.
