SeaDoo buddy, I understand your concern on jackets. Rfoster, i understand your concern on investment.
Like all seadoo boats of this hull, the deck is designed to drain once back up on plane. So the water is isolated to the floor unless you open the ski locker, or cannot get it back moving again. This one was bigger than anyone had expected. That being said, anyone that was not a capable swimmer, or was under age had jackets on. Everyone had a hold of an O'$hit bar and was prepared for the sub. Of course someone could have gotten tossed or knocked their head. Thanks, I will take your opinion with a grain of salt then.
My electronics/amp are mounted up under the pod storage, and my speakers are water resistant and/or on the towers. The Alpine Marine 6.5" are up high enough that they would not get hurt either, and can take a splash. DO NOT DO THIS if you have a sub near the floor. That's an obvious issue, or if you mount your amp in the ski locker. Since neither of those were an issue, this was a safe manuever in all aspects.
One further note, the engine compartment will not flood unless you drain the floor into the ski locker. And if you kill the engine, there is little to no chance of the water getting in the engine unless it reaches the airbox and the engine is running. Engine electronics should be kept dry at all times. Again, that's if the engine compartment gets any water at all anyway and reaches the top of the engine bay.
These moves are as safe as you make them, but doing them without your passengers knowledge is just plain stupid. This was our third of the afternoon. The first two just being small splashes.
I would say the extra weight in the bow may have made this one bigger than normal, but I am surprised at how easy it is to dip that bow on this long of a boat. You won't be seeing me post any more videos of one this big though. I agree that it was more than should be done. All is good to this day.
