The ocean level remains the same. Why? The ocean rises one spit because you keep it in your mouth on the boat. The boat displaces the ocean by that amount. You spit, it is now in the ocean raising the level of water in the ocean by that amount, however, the boat is lighter by one spit displaces one less spit. Thus the sum is the same, the ocean is the same height. There is however, one factor we have all forgotten. The immortal laws of newton and acelleration. If you spit vertically downward the action reaction forces apply so there is a momentary acceleration of the spit downward which makes you and the boat lighter by more than one spit. Further research is needed to calculate how much lighter. The ocean level is momentarilly and correspondingly higher initially then after the recoil is absorbed the boat stabalizes then the ocean is one spit higher while the spit is enroute. When the spit impacts the ocean a whole new set of laws apply, to which I plead ignorance as we are now into hydraulics. There is impact, splatter, viscosity and other things happening which need further discussion and clarification and to which I plead total ignorance but intense interest on the physics. I am sure you all agree that this is a very important topic which needs complete analysis and agreement before we dare spit into the ocean again. This is similar to the classic problem of 20 pigeons sitting on the floor of a C130 in flight. The total plane, useful load and pigeons weigh X. You startle the pigeons and they are all flying. Is the total weight the same or lighter? The answer is, the same (x) because the resultant forces of lift, weight of the birds is transferred to the air and ultimately from the air to the floor of the C130. Have fun.
