im currently in a malibu mini-x its the smallest kayak i have taking offshore though i have been out there in about 6 different kayaks over the 5 years i have gone offshore kayaking, on calm days like that one its entirely possible to make it miles offshore and land fish just as big as boats can, you also are a ghost out there compared to power boats, i would way rather fish from a kayak that a boat with a noisy motor..i managed to land a massive stingray with a 7 foot wingspan from that little yak as well. part of the reason i fished the tournament was because there were two $1000 offshore kayaks that were prizes and i sure needed one of them, my buddy ended up with one of them though
the only real limitations i have found with that yak are speed(its not fast) and swells over 2.5 foot can wash over the top of the yak if you take a swell sideways, most offshore kayaks are 12-16 feet in lenght and you will get more speed out of them, i have been wanting a hobie revolution for years but they are expensive (but its the Ferrari of the yak world and i dont think any other kayak can keep up with it)
