I fished with Captian Mark with Fishy Booty Charters http://fishybooty.com/
last August out of Grayton Beach. If you are in Seaside then this is really the only place they launch. I was staying in Watercolor. Grayton Beach is a 10 minute drive from Water Color/Seaside. I think Mark and two other guys run small CC's out of grayton beach. They'll pick you up on the beach and drop you off there.
Wind was rough every day I was there but managed to get out and fish with him one day. Nice ride. We caught amberjack, trigger fish, a bunch of red snapper (it wasn't in season) and other various snapper that were pretty tasty.
Lots of pretty warm water with lots of sharks. We had to reel up as fast as we could to get our fish past all the bull and black tips.
Toward the end of the day we went near the beach and shark fished a little, they are really close up to the shore there and all over the place!
