Effects of transit from SW to DW are due to change of water density:

1) Buoyant force of a vessel is in equilibrium with it's weight:

Fb = buoyant force
ρ = fluid density
g = gravitational acceleration constant
V = volume of displacement

Based on above formula, if density decreases (fresh water) volume of displacement must increase because weight and buoyant force remain same

2) KB = Draft / 2
As we saw above, volume of displacement (and draft) is greater in FW. Therefore, KB is increasing when moving from SW - DW

3) LCB and LCF are increasing because draft is increasing
