Offshore can be a short rip out of the bay to jump some waves?...or getting to some destination across open water ?
Seems foolish at best, could become fatal at worst,... these boats are not designed to operate in ocean swells which can quickly go from calm 2 or 3 footers to many times that. Take one big one over the bow, and as the saying goes...your sunk.
I sailed for years, in boats specifically designed for ocean conditions, high decks, 3 ton lead keels to keep the shiny side up and still had the krap scared out of me on what started out as a calm sunny day...Maybe consider skateboarding off some roof top, onto a rusty pipe railing...seems a far safer, far less expensive way to get a thrill...
Of course this is JMHO, ....and yeah, I'm an old guy, but maybe one who got old by respecting mother nature and not trying to use things for purposes they were never intended for...
