Re: *** rip it till u flip it??? ***
The sleeves are for loading small caliber ammo, they sell different calibers. A standard 12ga. shell would blow the gun. It would be illegal to shoot at another boat with a firearm in most cases,there are exceptions. White flares is what I carry next to me right next to the air horn. I keep one loaded and ready for action when I'm in idiot filled waters. A red flare used for that would be outright illegal, a white is designated for general alerting purposes and should be legal as long as nobody gets hit or burned by it. Even if you do 'accidentally' hit the boat or operator with one, it is arguable that you were preventing more serious danger--maritime law vs. regular law.
As for jack-*** maneuvers, to each their own. If you don't endanger any unwilling participants, enjoy! The problem lies in the unforeseeable; driver ejected, broken steering or throttle, etc. that could leave an uncontrollable boat to endanger someone else. Life jackets are your choice, a safety kill is your responsibility to all the others enjoying the water. Things happen: my last trip ended when a steering hose blew and we were slammed sideways into a big swell coming down from 55+MPH jumping; 'till then it was fun. A sudden stop from even 20MPH is more than most people will be able to brace for, and don't forget what they're holding onto also has to handle several hundred pounds of force in any direction. I can tell you that there's no bracing in the world that will keep you in place in some instances. No matter how much your passengers are on-board with fun, when someone gets hurt it will lie COMPLETELY ON YOU! That said, enjoy your boat!!! and the knowledge that you are willingly participating in potential population reduction. That boat -should- have full floatation so it shouldn't completely sink even tho it will possibly be damaged beyond feasible repair. Every hundred gallons of water will weigh about 800lbs. so you can do some rough math on what it'd take to make the boat an inoperable floatie. A high output bilge pump will help lessen the time it takes to pump out, but if it gets enough all at once to put any upper surface of the boat below water you're done. If you really want to prep for the sinking, add lots of floatation material in the right places, then you can run it like a jet ski and never sink.
