The pressure will almost certainly drop once the boat is in the water due to the cooling effect of the water. Just attach your foot / hand pump and top-up the tubes and floor (if you have an air floor). On training courses I get the students to check and top-up the rib tubes if required at the start of day two.

With the boat in the water and being used it should be inflated to the correct pressure, so 0.25 bar for the tubes. When inflated and ashore most people drop the pressure a bit to allow for fluctuations in air pressure due to temperature variations. You can get big temperature increases without the cooling effect of the water on the tubes. An increase in temperature of 10 degrees Fahrenheit will increase the pressure by 1 psi or 0.07 bar.
If the pressure drops when the boat is on the water do you pump it up to the correct pressure? If so, how do you do that ?
