Heh, we used to go offshore when i was a kid with nothing but a compass. We never really went more than around 30 miles out, but we just checked what our bearing was heading out, and reversed it to come back. Never had a problem being off more than about a mile or so. I still think it is amazing that we used to go so far off shore in a 19ft Whaler, with little to no electronics, single engine, and have an absolute blast. Never fished bottom structure back then, usually either went out to the exxon rig, or found blue water, and trolled the rip for kings / dolphin / hoo....man i miss that stuff.
Now people freak out if you go out with anything less than 2 outboards, epirb, radar, chart plotters, and a 30ft boat. I dont see how people afford it these days.
