i prefer salt water fishing... well one because I'm surrounded by water so many kinds you can do here...
1. coastal fishing on the inside/just outside reefs
2. deep sea (you don't have to go very far out)
3. shorecasting
4. three prong for tako (octopus)
but ill say having a boat sucks at times... plus the fresh water ways have it a lot easier in terms of care... i spend half the time soaping and washing everything down from the ocean water than i do actually fishing in the ocean..... you sh#t last a lot longer in fresh water... boats in hawaii are expensive... if i lived near a lake or whatever i wouldn't need a monster boat... plus hawaiian waters get rough... so if your non commercial but serious most guys have id say 19-25.... id like to get myself a 17 footer doe.....
