Planning my first trip to the big island this wknd and next week. We plan on inshore fishing for spec's and reds, but if seas are favorable I'd like to take the BW offshore for some mangroves. I fish VB so we generally need to go offshore 20+ miles out in order to get into decent water depth to fish mangroves. Approx how far out of GI does one need to go out in order to get in mangrove territory? And what area is better, GI blocks or West Delta blocks?
As for inshore fishing: Is there any area's that I should know about that I should take extra caution (Shallow reefs, wrecks, under water danger). Thanks in advance for any advice and pointers you may feel like sharing.
