What I've been told is they cancel when the waves are over 3'. My 1st attempt got cancelled, but they had an opening the following week that I got on. God smiles on fools & idiots I guess since that let me get there for the coral spawning. Corsair & Sea Wolf got cancelled 2 or 3 times last year. They did make it out with the rest of the Texas Swampers this year.
