Colored boats require more upkeep than do white ones, generally speaking. And it looks like the blue one is in need of a "make over", as it is.
Also, the blue one has dead lights/ports in her topsies. Which are notorious for leaking.
That, plus her chainplates are directly afixed to the
hull. And such are more prone to
leaks than ones which penetrate the
deck, & attach to
interior structural elements.
I can't say with any certainty if the ones on the white
boat are mounted differently, but if they are, then that's another strike against the blue one.
