from Galveston to Corpus Christi (that I remember), with daily rates. Galveston is tough, because of Ike:
Harborwalk (just past the I-45 bridge)
: Seaside is new, on the island side.
Matagorda - I've never been there, though
Port Lavaca - it's off the ICW
, but should have transient slips except on holidays
Port O'Connor - If you draw over 5' you will get the T head

Rockport - City Marina usually has room. Key Allegro can generally squeeze you in.
Port Aransas - as long as it's not a busy weekend, like Harvest Moon or a fishing
Corpus Christi - there's ALWAYS room here! Great marina, too.
