I'm looking for some feedback on the safety or lack thereof, of getting in the water far offshore. In the northeast US, we run approx. 80 miles offshore to get to bluewater for sportfishing. These waters are over the continental shelf/canyons, where it drops from 600feet to 6,000 feet. I am thinking about getting in the water to see species such as mahi, porpoise, tuna, ..... maybe near lobster buoys, or other flotsam. What I am concerned about is mainly dangerous critters. We have makos and bluesharks mainly, but there is the rare appearance of a tiger, white, ...... Also, what about any dangerous of going in the water with porpoise, which I think are Atlantic bottlenose.
