dude, do you have a death wish? there are so many things that could go wrong. if none of you have any families and no one is going to miss you when you die then go for it. it sounds like you have a very limited understanding of the ocean. are you aware that there are currents that can move faster than you can swim? also, i think its impossible for you to carry adequate water to prevent dehydration. you need some more time with the ocean(a few years at least) before you will understand how crazy your idea is. anyway it sounds like your have a great adventurous spirit. i would hate to see that wasted by doing something stupid that gets you killed. my advice would be to start small. learn basic freediving techniques. work on dry static breatholds. get some entry level freedive gear and spear stuff. continue your other conditioning. do a bunch of shoredives(within a few hundred meters of shore), then maybe look into getting a fisherman to take you to some outer reefs. once you get acustom to the area you could rethink some sort of spearfishing marathon. also read about shallow water blackout.
