When I did this air temp was prob in the upper 50s. So when it is summer and its 90+ does that mean it will repressurize ie cold air is more dense
actually, scientifically speaking, more air pressure inside the mast will decrease the buoyancy.
Hw does this work?
Buoyancy is a function of density (mass per unit volume). Air has mass. By increasing the pressure you are thus shoving more air into the same sized volume, increasing the density (more mass for same sized volume). As your density goes up, your buoancy will go down. This is such a small difference I don't think you would ever see a difference unless you are pumping 15,000psi into your mast.
